Good video. You did a great job at taking the high road and not insulting Jeff but provided a different opinion for your viewers. There needs to be more respect in You Tube in the riding community, we all sweat, break our bones and spend our hard earned money on motorcycling.

The extended reach plug is used due to combustion chamber shape, when going to a high compression head that shape is changed. Using the standard reach plug in a stock head does not change the timing, it changes the way the combustion flame front propagates. Yes with a stock head definitely use the recommended plug.

Well done Kyle, correctly spoken with your experiences, as you know people's opinions are based on their own experience and you have done the groundwork to back up your opinion. Keep up the good work

You do a great job! Great video and we are glad you do these videos. Always informative! Good to see you are back on the bikes also.

Wow! I would have to say you have some of the most respectful, knowledgeable and appreciative followers of your videos on the planet ! You did an excellent job on uncomplicating this spark plug situation without dissing Jeff ( who can come across a bit grumpy at times).Very well done ! I have the upmost respectful for both of you !

Thank you for mentioning the higher compression. I think a lot of people were confused and thought if you revved out the bike it was going to grenade.

Well done!!! This video was great! Stand up for logic, make people understand the time engineers put behind basic choices in a design.

Excellent vid mate! Hats off to you for challenging Slaven’s racing - precision in communications is so important, and I think he missed that opportunity. You did an excellent job in explaining that. I always agree with OEM, except for some very few circumstances. Keep up the great work.

Great video. I guess it just goes to show you that not everyone on the internet knows what they are talking about. I am glad you got that sorted out. Thanks for taking the time to check/verify your results. It looks like other people are experiencing the same results.

Kyle , impressive 👏 effort making your videos ! You humble yourself among the expert dirt bike mechanics world , but make no mistake that each and everyone of us that own a bike must learn basic mechanics to keep the beast running. I'm the guy age 65 that raced the Honda Elsinore 125 AMA AMATURE back when it was first unleashed in the Marty Smith days! And today I'm back on a 2019 KTM 500 EXCF after 46 years. I rode in Pa. Trail Riders 96 miles event last fall and what an eye opener. This all day ride first ever over washed out mountain roads and single track made me grateful I was wearing some of the best crash protection ROCKY MOUNTAIN has to offer. Now for the reason I'm commenting! I see a few videos for you to work up that are important subject matter for anyone looking to buy into the dirt bike world. Anyone that owns a bike MUST realize that you just don't buy a bike and ride without knowing you've just become a back yard mechanic at best. I have invested in ROCKY MOUNTAIN'S TUSK WHEEL BALANCER ,TIRE STAND , TIRE SPOONS , YAMALUBE TIRE LUBE , VALVE STEM TOOL, RIM LOCKS, SPOKE TORQUE WRENCH, WEIGHTS WEIGHTS ,the list goes on . My point here and this is only the tires and wheels of the bike. You need a video to make the point you just cannot expect to invest in a bike and the investment stops there 😉! Another video might explain the different protective gear that is available tailored for the type riding you choose. Make the point that money invested in the best gear to avert injury is money well spent. Again ROCKY MOUNTAIN ATV MC HAS IT ALL AND CHASE'S VIDEOS ALSO GET YOU THROUGH THE BUMPS IN BECOMING A MECHANIC! KEEP SMILING 😃 AND THROW THAT DAMN MASK AWAY ,LMAO ! WALT SPRENKLE

Thanks man. I was going to try the plugs but was really nervous about it. Iridium gap was much smaller than the stock plug. Seemed wrong. Gapping the new plug would put quite a bend on the plug. Thanks again.

I agree It’s an ignition timing issue for me, if you move the ignition point in the combustion chamber you also move the “wave front” of the explosion, effectively changing the ignition timing as described.

Honestly thank you for making this video. People talk out of their asses for views and people believe it. Cheers mate

Awesome video! I have a 300 tpi and i plan on running the stock plug as well.

Kyle, thanks for the ineresting video. I just bought myself a 2017 150 SX and wondered if the advantages you listed for the larger gap plug - better combustion efficiency etc. - can be translated to other engines as well, like the 150 in my case. Or would I just run into different problems? Running the stock head so far. I absolutely know that sticking to KTM's (or NGK's) recommendations is the primary way to go, but I'd really like to have your take on using larger gap plugs in different engines. Awesome channel and great videos, keep it up!

One thing to note is that Jeff Slavens always pushes his Slavens Mule packages on every Ktm and Husqvarna model - every year. It includes an S3 head which indeed is high compression. I have a friend who has a 250 TPI with the S3 head and his stock plug got destroyed. He was one of the customers Slavens cited. I think Jeff’s frame of reference is from a person with a modified bike - his type of customer. And you are so correct to point out that Ktm just might have an engineer or two who know a thing or two about combustion. Thanks for your video!

Just qurious the s3 head offers more compression so it runs hotter so i would and have in the past go 1 colder in plug range and plug chop the bike.

I am a motorcycle mechanic 35yrs. All my bikes are 2 strokes. Engines that run projected plugs have slightly different combustion chamber design to accommodate. RULE NO 98 - NEVER fit a PROJECTED PLUG in an engine that runs a short projected plug as STD! (Opposite to what ol mate did.) You WILL end up melting a hole in your piston!! Just use whats recommended pepps! If you want somthing special, just go irridium version of the RECCOMENDED SPARKPLUG. Projected plugs put the flame fronts ignition point closer to the top of the piston, more central in the chamber, std plugs start the flame front closer to the top of the combustion chamber. Generally, the profile of the piston top and combustion chamber shape are different in one way or another to accomodate different plugs and achive different ignition points and burning profiles of the fuel within the combustion chamber. The reason he melted the plugs earth electrode is likely due to other causes, i.e. high altitude, low octane fuel, engine overheating, air leak-lean mixture, timing too retarded, etc.

Thanks Kyle, I had watched Jeff's video and picked up on the compression comment as well but I purchased four BR7EIX plugs from Amazon anyway. None of the local shops carrying them should have been another clue. They are still new in the box and will remain that way Until I can determine if they can be used in our Son in laws 2000 250 EXC or my buddies high compression Lectron bikes ( I must agree with the high compression Lectron boys, their bikes rip compared to my injected bikes however rip has never been my friend in the deep dark woods). Tokyo off road next stop. I learned how to jet a carburetor from some old boys from Orofino Idaho and we never experienced any fouling after that, just elevation change jetting. I love my 300i better than my old 250i. I will not go back to a carburetor unless they make me. They can only get better.

Great film kyle,it's been worrying me about slavens advise,standard plug in standard bike,makes sense! Thanks for sharing.

Great video. I had a similar problem with my bike, saw this, and put the longer reach plug in my 300 tpi bike and she runs great. Thanks for the information.

I heard some folks talking in my local powersports shop that some people have been experience issues with the longer stock plugs where parts of the center electrode were chipping off and destroying their new motors. That was the biggest reason folks around here were recommending swapping out the stock plug immediately.

Another option may be the bpr7es that is also extended tip not as extended as the oem plug tho. May be worth a shot if someone is looking for a lower cost replacement.

A cheaper version of the projected plug is the BPR series from NGK. So in this application, the BPR7ES would be the cheaper alternative that will run well.

This may already be in the comments but it was my understanding that Slavens was recommending the old plugs when the bikes are combined with a high compression head and haven't been re-tuned. The newer style plugs are fine on a stock bike but can't handle higher temps with a high comp head due to leaner stock tuning, so once it's tuned you can then run the OEM plug again. You talk about this later in the video but plenty of people will probably comment on only the first 5min of the video.

Great stuff here. I also like both other vid guys you speak of in this tutorial. I am assuming you are only talking about the TPI or FI model bikes for this longer reach plug? Also what are your thoughts on running the BR8EIS plug? I have heard from others that the carb bikes run better. Not sure if you know or not. I'm going to try it. I have not added compression to my engine and while using the Lectron carb, the BR7ES plug is running very lean here in southern AZ at about 4000'. I've talked with Lectron until I was blue in the face and they actually did a rebuild on the carb for me.

Hello have an 300 -18 tpi and experiens exactly the same thing as you kyle when i change the spark plug to ngk br7es. Change to standard and it runs perfect again Martin from sweden.

I Always stick with stock. Well done for trying and giving thorough feedback!

I put a hi-compression head (S-3) from Slaven’s on my 2019 KTM 300xcw TPI and you can definitely tell the difference from 0 rpm on up. It’s very linear and keeps pulling forever. Love it. Also use the stock plug (pricey) but so far it’s worked fine. Adage, don’t fix what ain’t broke IMHO. Thanks for the videos Kyle, really good stuff.

On my 2017 XC the only non-stock item is the lectron carburetor which performs well. On my 350 FX I have only the aftermarket fuel rail and 13t sprocket which does help with flameouts a bit. All the other “fixes” have either not changed performance Or made it worse, that’s just my experience, and I’ve spent A LOT of money. Like you said once before, the best upgrade is to just get out and ride and get better at it and understand how the motorcycle works.

Nice video as always Kyle 👍 i have noted that i am using more and more OEM parts. I can understand why people sometimes chose ATF-parts if it is a big price difference and you are shorte on cash. I think when it comes to engine parts, OEM is the right way.

Top Video!!! I would like to ask you a little question. What a spark plug reference would you advise me to put in my ktm 50 sx 2016? advise the model that the bike brings or is there a spark plug reference that works better?

Why one would actually believe with KTM’s vast pool of knowledge/experience, they would not know which spark plug to use? Also, where in AZ did you go riding?

Hi Kyle I have a 2020 Kim 300 tpi that comes stock with the br7es plug over here in England I haven't had any problems. Love your channel too

If a plug is too hot (#7 vs #8 etc) it can cause pre-ignition. Maybe the extended plug isn't the problem but rather the temperature of the plug. Conversely if a plug is too cold or too far away from the designated combustion area it could cause less than complete burn but less likely to affect ignition than too hot of a plug. While maintaining factory recommended plug length, it might be worth considering the plug temperature or plug gap to ensure complete compression and the optimal air-fuel mixture encompassing the plug spark before ignition. PS- By the way NGK plugs, the lower the number the hotter the plug and the higher the number the cooler. Seems silly but that's the way they are.

From the info I gathered the projected nose holds more heat at low rpm but will cool faster as air/fuel flow go up. Trials bike's run them.

Kyle, been a fan for awhile now. I understand it wasn’t your intent to call out Slavens on his spark plug scare but I’m glad you did! I agree he definitely has a ton of knowledge but he definitely does talk alot of smack in a very arrogant tone often as I experienced personally on a PM asking a very legitimate question regarding the Vortex ECU. Thanks again for your honest and humble opinions and making us all feel on your level. Cheers !!

Honestly Kyle I would just go with the plug that KTM recommends and owners manual because those guys went to school to become a engineer and went to work on these KTM Motors and are probably paid hundreds of thousands of dollars a year to make those Motors the best Motors they can so yes OEM is good. Great videos Kyle and keep them coming.

Informative as always

I did the same thing on my 250 and it ran like a carbed bike with the choke left on. I switched to the stock plug. Thanks for the confirmation Kyle.

@DirtBikeChannel

5 жыл бұрын

happy to help.

What you're saying makes sense in that the ignition point within the chamber is very time/position sensitive and placing it deeper in a standard chamber should give it the correct timing for max burn rather than incomplete burn. I know from my own experience that when I cut my head on my Husky's I had to experiment with a different temp range to get optimum burn. The same happened when I had a machinist reshape the head on my YZ 465's to give a better squish band to quench end gases.....it used to get as hot the the Sun when I pinned in the desert on air-cooled bike.....different conditions call for adjustments in timing/spark/jetting. I rigged by choke up on a cable so that when I was coming into a check I would thumb the choke until it blubbered....thus cooling the chamber with raw fuel before I'd let off to save my engine. You modern guys have it nice compared to us old farts. I found a lot of times the heat range would be in-between NGK numbers and then a Bosch would many times be my go-to plug. Bosch heat ranges slightly different....they still supply plugs? Keep the Faith, Tom Enjoy your videos...wish I was younger....still riding, tho.

Great videos. I often share these useful stuffs to our Hungarian enduro Klub. Greetz.

Kyle, I have tune a lot of bikes for enduro guys in Puerto Rico unsing a Dyno. Both 4 and 2 strokes. And I used ktm tuning tool. Just by looking at those spark plugs I can tell is runing on the rich side. Just enough to foul those plugs. Ktm should fix it with a reflash. And this is common in new models. They will have to change the maps till it accommodates for better riding. A/f is still the same on any bike. And to complicate it a little is Open loop.

to be fair, my guy Kyle there could have just gone straight in the video and just basically told everyone that Jeff doesn't know what he is on about but he's such a nice guy that he was like nah lemme just be nice here and just offer up my opinion, this is how youtube should work, not just a load of youtubers beefing each other over nothing. Supporting DirtBikeChannel since Day 1.

You and Jeff both have good intentions. Video was great.

I can confirm what you said . I just had problem with my new KTM 250 2020 after 20 hours of running, my spark NGK ZGR7GI 13G not able to power on the engine and I had to change it temporary with a spare sparks BR7ES just mount it temporary . Seems that my bike running totally strange with this spark , and I feel that losing the power , even the sound is quite different ... So definitely I will change it with the stock one. Now I have difficulties to find a new ZGR7GI seems that there is nowhere on stock even deposit.

When you say that the high compression engines may need a different plug, that makes sense to me and I agree with that. Cuz KTM sells the bikes with the extended reach plug for a reason, and they have tuned the bike to work with that plug. So if you are going to change the overall tuning of the bike then you may need to Change plugs but other than that I'd say you oughta stick to what KTM says to use

Could be the different base gaskets ktm uses are different height , I believe there are 3 sizes for each model, this could be a issue, I'm not a professional mechanic but do full rebuilds .

Have to agree with the points you've made here with one caveat. I too watched that vid from Jeff and I was shocked to hear his comments on the situation. However like you I can't imagine KTM Engineers don't know what they are doing. That said Jeff is very intelligent when it comes to motors and tuning, likely knows as much about it as any of their Engineers. So my thought here is that while there may be an issue with those extended spark plugs the problem is not with the bike but in fact the problem is that NGK needs to maybe change the design of that plug or change the material so that it can't fall apart as Jeff has shown. Granted this issue really only affects those who want to bump their compression up........ Anyhow, love the vid, keep the good stuff coming.

KTM didn't release TPI after spending weekend in a garage. They did years of research and I'm glad that we have such company that it's pulling new things on market. Comparing to Japanese bikes there are tech the same for last couple of years. I'm not saying that they are bad but having TPI in 2 stroke is really big step. 10 years ago everybody would be laughing.

@Horgh totally agree but find me perfect bike. KTM should have better suspension OOTB like Kayaba but not have it. If Yamaha would be cheaper (or fully loaded) comparing to KTM/Husky I'd chooseYZ250FX (because WR250 can't be compared )instead of EXC-F 250. But looking in the future, it's better to buy KTM because it'll sell faster and price not going down. like you said 9/10, I think it's a good score but I'd give them 7/10.

The spark plug design is pretty integral to combustion chamber design which is probably significantly modified vs the carbureted version. Convincing arguments, Kyle, and tactfully presented.

The extended reach plug will work in a high compression engine... my bike is 12.0:1 compression (4t) and uses that style plug and so do other bikes that run 13.5:1 compression. The biggest factor is the reach (the head it’s designed for) and heat range of the plug which will effect the combustion of the fuel. Basically run the plugs recommended for the engine.....

Slavens has some great videos, but I just don't get the "I know what I'm talking about so listen or shut up" attitude. In my experience the ones who have decided they are experts and no longer need to substantiate their claims are the ones who are starting to slip. This plug issue doesn't even affect my 2006 250 XC-W but it caught my interest (one day I'll own a new bike!) Whoever is right, your approach to testing, sharing your experience, and respectfully presenting it to the community is hands down the only way to operate. I like your videos a little more every day! Keep it up man!

Pluggate 2018. I'm just over here on my carb bike like braaaaap

My friend and I both just bought 22 ktm 300 xc’s one came with the Z extended reach plug and the other came with the standard br7es right from the factory

4 Years later with the TBI Bikes in now I have the TC125 Fouled the new Plug for putting on green map maybe I should consider getting a older spark plugs as they don’t have the current ones in stock yet 😪

Bravo. Well done.

Sounds like a high compression bike needs the stock style plug but a step cooler if it's having a plug issue, I'd also wonder if they need to be running race gas on high comp heads.

When the BR7EIX plug was used was it gapped according to the stock plug in the manual at .051" or gapped at .028" as recommended by Slavens? I know you stated "gapped according to spec" but want to be sure. I decided to try this plug in my 2018 250 TPI Husky and it runs fine. I did put in Jeff's idle screw and closed up my air screw. Is it possible the BR7EIX plug works fine because I am running a richer fuel mixture.

Just bought a 2020 model and now they come with the BR7ES plug. Is their a reason for the change or should I switch.

Good points. I still always carry an extra plug if I or a riding partner down a bike.

What spark plug do you think is best for a 300 xc

Kyle, do you have a video out yet commenting on the over heating problem on the new tpi bikes ?

My 2021 comes stock with a BR7ES. They did end up making the switch.

Hahahahahaha I typed my previous message like 1 minute into the video and indeed you know about Tokyo Off-road. Lol.

I have a ktm 250 xc 2015 what plug should i use..as wen im riding 1st gear seems to be abit spluttery

My 2022 GasGas EC300 says in the manual that the standard plug is the BR7ES. So maybe something has changed.

Ktm exc 200 motor 2th should we use any kind of spark plugs

Hi, little bit off the topic, what would be the best plug for a 2014 300?

I have a 2020 KTM EXC 300 TPI (European Version of the XCW). To my surprise, it came stock with an NGK ZGR7G1 (even though the manual says BR7ES). I installed a brand new BR7ES spark plug (after 36 hours) and the bike runs pretty bad compared with how it ran with the ZGR7G1. I am no expert but the difference is noticeable. I like it better with the ZGR7G1 it came with so I am going back to it. Thanks Kyle for this video and the reference to Tokyo off road's video.

It's probably a 2019 bike that was sold in 2020. Check the frame and engine numbers.

Hi Kyle. How does this all translate to the 2020 TPI bikes ? Run the stocker or BR7ES as per manual ? Dealer has told me to run BR7ES.

Well tks for this vid... yesterday after watching jeffs vid , i bought the iridium plug he said... now tomorrow im going back to the dealer again and change it for the oem plug... 😅

please suggest a plug for a old 2008 KTM 300 xcw. currently running BR7ES.

I think a lot of people just paid attention to the changing of plugs and not what he actually said in the video. Slavens specifically says potentially mistuned high compression engines. I think people are giving him unnecessary grief. No need to change the plug on a stock bike. I also expect the problem with the tpi bikes is that a lot of people who arent familiar with tuning a 2T are putting high compression heads on them and just riding them with no additional tuning. Depending on how and where you ride it may work but a lot of time it wont and youll get detonation. Its good to use an aftermarket ecu if you run a high compression head. Im using a GET ECU. Im running the BR7EIX with adjusted tuning.

My 2021 250Xc calls for a NGK BR 7 ES, thats what the 2021 manual says, the the parts guide for my year and model, I pulled the plug to look at it after a few hours riding and its indeed a NGK BR 7 ES. I asked parts for a spare and they gave me a NGK ZGR 7 GI , I'm taking it back next week when I go up to buy my front Tubliss Setup. By the way the NGK ZGR 7 GI part no 55439193000 was over $20 and the plug thats in my bike is only about $3. For what it's worth the service manual for a 2019 250 or 300 XC W calls for the NGK ZGR 7 GI that you are talking about , The 2021 XC W are calling for NGK BR 7 ES just like my 250 XC. There must have been some changes to the bikes this year. It runs super good with the plug it came with the NGK BR 7 ES. Getting a bit complicated when ya get KTM dealer parts people confused about the plug your KTM takes? Note: My Experience as a Mechanic, I've been a Mercedes Benz Technician since 1995

Man that blows my mind to hear you have never fouled a plug. I bought a used 97 suzuki 125 and im fouling plugs like crazy. If im running a track im fine i get into the trails and im fouling em. Bumped my fuel mix up to 40 to 1 but still fouling. Trying to chase the problem its a real hassle.

i have been thinking these cheap plugs were my problem,i just ordered the original iridium.from what i pick up in these vids also backs up my thoughts.

Great video Kyle, before Jeff recommends things like this I'd hope at least he would have some actual data to back up his recommendation,I'm happy you didn't just hop on the train and we're honest about your experience with the plug change,,,will the graphics kits be for all makes and models?like can you order them for your specific bike?

22 te300i's manual says BR7ES. Not sure what's in the bike from new yet.

Hey man, i watch your videos alot and and i put you in high regards, i need some assistance from you, can you please suggest me what spark plug can i use for my ktm85sx 2022? Since the stock ones are not availble here in the UAE, any other alternate? How about br9ecm or br9eix Please suggest

Did you try the extended plug in your XC? MY 2023 XC is fouling plugs and wondering if this might be a fix

My bike came with the NGKBR7ES in it, Brand new 2023 gas gas EC250, 0 hours 0 hours. Do I get rid of it for a longer plug., I think I'll stick with the stock plug.

Sooo... My 2022 300 xcw came factory with the BR7ES. Yesterday I went through a deep hole and fouled the plug. My dealer told me to use the ZGR7GI-13G. Will see how it runs today.

Some great facts stated there mate.

The 23 ktm xc-w came with br7es. Did ktm change something in the piston shape?

Please tell me what fuel you run in your tpi bikes it says 95 in the Manuel

Extended reach plugs run hotter than standard reach. With TPI the fuel ratios are pretty much spot on so the plug has to be able to ignite the charge from idle to wound out tight. A cold plug will not properly ignite the mixture. You don't notice it at low speed because you don't expect much power at those revs. You don't notice it at high speed because even though the motor might be down on power there is enough for you not to notice a 16/th of a turn on the throttle. However, in the mid range you are expecting a little power for a little twist and it is just not there. Run those cold plugs in that range for a long time and you will foul them. The other thing to do is to look for the milk chocolate coloration that is produced on a plug of proper heat range. I will be dollars to donuts the extended reach plugs come out milk chocolate color and the regular reach plugs will come out like dark chocolate, if not black and oily.

So, on my 300 my 2020, the manual says BR7ES, but the iridium is mounted stock, and the BR7ES comes with the bike as a powerpart...

Ran in exactly the same issue with my 2022 Te250i. Short old plug runs like garbage. Fouled in 30 hours. Stock plug - runs magically. I only regret I needed 30 hours to realize that, and to find this video :(

would that plug work in a older 300?

Did you tested extended plug in carbed bike? :)

I think you’ve made a very wise statement here. Jeff is no doubt a knowledgeable guy but that doesn’t mean he can’t be wrong. KTM motorcycles are not designed by idiots.

UMM.. My kickstarter broke around 10 hours., and I barely used it. KTM sent me a new one. I couldn't get the old one off. They used red locktite on the splines, and I needed to notch it out with a grinder. . So there could be idiots working at KTM.. All that said I love the bike.

When you were in AZ did you allow the bikes cpu to acclimate to the lower elevation to rule that out??? 60 hrs on my TPI 250 stock plug. No issue. Stock motor.
