I keep the jetting simple. At/Near sea level, I just pull the snorkel, install an extended idle-mix screw, and install an adjustable overseas DR650 or a KTM640 needle. The adjustability is the key, if you like the stock needle taper. I can remove the airbox door and/or tune the idle-mix screw at altitude, if needed. I DON'T cut the airbox. Move the crankcase vent away from the airbox opening to eliminate surging. The stock main jet and pilot jet work fine at sea level with a de-snorkeled, uncut airbox and a stock exhaust. The stock, unadjustable, USA needle is a bit lean, especially after de-snorkeling. It CAN be shimmed too, rather than replaced by an adjustable needle, if richening is needed. With stock exhaust, these simple changes in snorkel, needle, and idle-mix seem to run great. My fording depth didn't change much. MPG is similar. Wheelies are easy. A bigger main jet may be needed at sea level if you use aftermarket exhaust and/or a big-valve head. Some guys at high altitudes actually also use smaller main jets and pilot jets than stock, often with a lowered (leaner) needle setting. With snorkelectomies and free-flowing exhausts, they report sometimes topping 60MPG with the smaller jets and lowered needles.

Well going by your reactions I would say you have reached that sweet spot. I think I'll do exactly what you did when I'm ready. Thanks for a great vid.

Nice video Kyle, glad the tuning worked out the way you wanted it.

amazing video, thank you. you gave me the confidence and instructions on how to work on my DR. I did every mod possible, but I was scared to work on my carb. Now im not scared, but excited!

You only need a Stanley knife to cut holes in the top of your air box. Using hole saws creates a lot of shavings that get every where.

Great series on the DR! I have had my eye on a DR for a bit now and found your channel searching youtube for DR project bikes. Turns out we are neighbors, i live in central . I wand to turn a DR into an Adventure bike and hope you continue to mod your bike in that manner. I think the DR is made/geared for commuters and people who want to build an inexpensive adventure bike. Keep at it buddy, i'm waiting for you to replace the tank, faring, bars, pegs and pannier. great work!

Easy to understand description of carb adjustments. Thanks! I just picked up a 2001 DR and the previous owner appears to have done a lot of mods including the airbox and I need to see if he worked on the carb. Your video will be helpful. Kind regards from the other end of the country, Vancouver Island.🇨🇦

Watched the whole video as I’m picking up my first DR next weekend. Very informative thank you. The bike I’m picking up has been sitting for a few years so we’re going to rebuild the carb since it was stored dry. I also ordered that same pro cycle jet kit (although still impatiently waiting for it to arrive). I’ve read in a few places that if you cut that carb spring down to 100mm it’ll also improve the overall performance of all the mods you’ve done. I’m going to try that as well. Bike already has the GSXR pipe I just need to modify the air box as well. I think I’ll go youre route as I don’t want a big gaping hole in it

Awesome stuff again

kyle, I have a bone stock Suzuki Dr 650. No Mods. Great Bike. But I Did do i wheelie in first gear with half throttle for about 60 ft. with no problem. glad the mods worked for you.

Easy way to remember on what jet to start with and then try to get to the exact one on the main jet. The scale for them are a little hard to follow. A 155 is sea level. Most fuel for the most air. A 100 is on top of the highest mountain. Way less air less fuel. Unless your up in the mountains, most will be a 125 or less. Mountain being 5,000ft too 6,000ft and up. Again, less air less fuel. More air more fuel. Then changing the air box or air filter to give more air then means bigger jet or higher number on jet. One quick way to know if you are wright on or off is after warm up and just before move the throttle just a little. If it wants to bog out then you have your jet to open or need to drop to an smaller jet. To much fuel is going into the carburetor. Example. A 125 jet and I give it a little throttle and the engine bogs. Then I need to go to an 115. Not an 130. 130 will put more fuel into it. Higher number more fuel because of more air at altitude. A slight movement of the throttle will for most tell you if your on the right track. Instant response of power, your on the right jet. Take care.

Actually, after full warmup, a slight 1/8 to 3/4 blip of the throttle is coming onto the needle from the pilot jet. The main jet is used more from 3/4 throttle to WOT. If you have no vacuum leaks or fuelflow issues, and it bogs from throttling 1/8 to 3/4 throttle, your needle adjustment is likely off for your altitude, intake airflow, and/or exhaust airflow. Partially cover your airbox opening and blip throttle again. If it pulls smoother, your needle is adjusted too lean. If it worsens with the airbox opening partially covered, your needle adjustment is too rich. To check the main jet, accelerate WOT from lower-mid revs in 3rd gear. As it just starts to really pull, back off the throttle a hair. If it then pulls harder, your main jet is not quite right. Partially tape off the airbox opening and try again. If it pulls better at WOT, your main jet can go down a size or so. I once had a weird issue from a fuel tank vent that partially plugged. The engine was starving for fuelflow as I throttled up. IIRC, this is not exactly a rare issue with the locking plastic fuelcaps.

@@RKmndo when I put on my racing carburetor. I didn't have any problems. Except I needed more HP. No matter what I did to set the idle down. The engine was an runaway. Meaning my main jet was to big. I needed to loose fuel flow. After that my fuel bowl had to not enough fuel. Using the throttle it would die. Yet after research. Is where I found out the settings I said. Not having fuel tank problems or anything. Just putting on an new carburetor and adjusting it for altitude. Highest altitude. Main jet or center jet less. Outer jet more. Sea level. Center jet more and outer jet less. High altitude less fuel and more air. Sea level more fuel and less air. Just an easy way for me to remember. When my engine was new with the new carb and on that runaway. I almost lost my new engine. Your way also. Thanks.

My MZ660 was OK. I put a M4 exhaust on it and a stage 3 carb kit on it and it fn rips. 1st gear can make you black out. Great video bud.

I did your carb mod a few years ago. Great improvement. But wait until you get a tm40 pumper. Ps I have a extra high a boosa 1300 muffler. I bought two back when I changed out the stock. Had to buy the pair.

fun project.. thi 650 was going to be my first bike. same dealer had an ftr1200 and it won as I ride on pavement mostly and the occasional Bush road

I'd have liked a baseline for fuel consumption, zero to 100KPH, timed 500M and then same with the upgrades. The upgrades obviously (from the look on your face and your voice) made a huge difference. Excellent video.

Hey Kyle. Thanks for posting. Info for you. The old screws weren’t Philips, they were JIS. Good to buy a JIS driver before they stop making them.

Hey Kyle, love the mod, seems like you have way more power. Just have two questions. Can this mod be done with the stock exhaust system, and how does the mod effect gas mileage. Thanks

Nice.

Good video, creative thinking, good understanding of what is happening. But that sweater...😳

Not sure if you can get your hands on CCM spares where you are but the CCM 644 uses the dr650 motor BUT it has twin carbs so if you could get your hands on a CCM 644 the R30-(super moto version)- or the 644DS-(dual sport version) on my R30 it was up jetted and the air box lid was just removed and made a big difference.

I cut the top of my airbox off and man did I end regretting that. I tinkered with that dang carb for so long. I ended up going with a 145 main jet, 3d printing a new top that was identical to the stock snorkel hole and running it like that. Small improvement in power and bike runs like a top. I will say that I put the 155 main jet in the bike and WOT and jeezus the bike almost pulled my arms lol but it sputtered all the way up to high rpms and then just took off like a two stroke. I never could get it running smoothly messing the needle and air/fuel ratio.

There is a fine line to walk, but mine ran like a dream! Set-up is KEY. My Dad has one that had the work done before we purchased it. Their airbox work was too much for what the carb could mix fuel with. It was no good.

Hi Kyle great video mate. I have practically the same setup as you. Procycle jet kit, Barret pipe and mid, air box fully open and tried it partially closed. Main difference is I have 14/42 sprockets. Does that make a big difference? Can you tell me how many turns your mixture screw is out? I know you started with 2 like you’re supposed to but after the tuning what did you settle on. I still can’t get the front wheel up in first gear? Not sure if it’s just the gearing or the tuning? Thanks Kyle

poipe and boike. I thought I recognized that accent. NL licence plate!

Best video great job stright to the point

Hey Kyle great video and I know its 3 years old but I didnt catch what clip position you choose on the needle

the air box does not affect the fuel mixture...period ! it only does if the manufacturers got the hole size wrong, which for some reason is fairly common ! putting 2 large holes in the top of the air box should be more than adequate !.... do not re cover them for any reason. fine tuning the fuel air screw is the major improvement ! I recommend a portable RPM gauge that runs off the ignition, they are far more sensitive to air screw adjustments than your ears are. adjusting the RPM to peek RPM by the air screw, then reducing the idle screw and re adjusting the air screw again is my preferred method. also do a plug color check stock the plug color will be very light tan to almost white.... that is BAD for power and heat ! the closer you can get the plug color to chocolate brown the better off you are Plug color is a product of the main Jet... if your plug now runs black it is too large reduce the size by .5 , then re adjust the air screw for best mixture , use a new spark plug so you can quickly see the color it is running at then do a 15 min run the spark plug color tells you so many things ! your looking at the porcelain below the sparking tip of the electrode not the metal wall outside. a brown to dark brown color is best, this was a Major Killer of 2 strokes back in the day guys would run them too lean and melt pistons, todays 4 strokes benefit a great deal however by having the mixture at just the right amount for a bigger boom ........ always carry 3 new spark plugs with you.... it's a single cylinder, it must have good spark to run... it is common to have a spark plug die on you 1 in 4 are bad from the factory..... back in the 1970's I had as many as 6 out of 10 new spark plugs be bad right out of the box, their better now , but not by that much ! .... don't kill yourself !

Thanks Kyle. Very useful. I have gone through some of the other videos but yours seems to be the best. Some others have also drilled a third hole in the slide. The instructions that I received with the procycle kit dont mention drilling of this hole and I havent seen you doing it in your video as well. Just wanted to know if drilled that hole as well or went without it?

A few more details would be nice. I wanted to hear more of how much difference the pipe made...

Have you ever tried taking the header pipe off, then welding the header flange on the outside, then grinding all the weld out of the inside of the flange? The last DR I did that on, the amount of weld on the inside was staggering. It literally had 1/3 of the pipe blocked off. The welds are usually sloppy and over 1/4” high. So as you can imagine 1/4” tall weld all the way around a 1 1/2” pipe is a HUGE restriction.

@kyle_noseworthy

4 жыл бұрын

I removed the header and had a look. My inside weld was very clean, and moderate in bulk. I ground away probably 50% of the weld on the inside. Not enough to compromise the pipe, but enough to really open up the air flow. I'm happy with it.

Id like know what kind of knife you we're useing..looked pretty nice!??

Yea it's likely getting WAY too much fuel. If you only have a few small holes, I'd downsize to maybe a 150 main jet. A 175 is just silly. I believe a 155 is about the richest you'd want to run a DR650, to have smooth and reliable performance.

If you are holding the needle with the pointy end down, then is it 4th from top?

I would have liked to see you demonstrate the front end rising from throttle bursts on pavement.

What knife are you using in the vid? I need me one

This mod slightly increased my fuel consumption, nothing major but for some reason suddenly my rear tyre is wearing out very fast......., The extra response and power just makes you ride it harder. For the stock guys i would recommend taking out the needle putting it in a drill and tapering the stock needle on some sanding paper just a little, no major power gains but it smoothes out the power delivery a bit, think the stock needle is so crappy due to emissions BS they had to meet and they knew anyone could quickly fix it with a drill and sanding paper. I tapered mine from about halfway to a almost pointed tip, but i guess less is always better when in doubt. I also just drilled the stock jet out, put a 1mm drill bit in and wore it out as even as i could till i felt i had enough copper dust/shavings to justify a improvement, and i did it twice before i had the desired effect, i would guess I'm at around a 150 jet size as a 1.5mm drill bit barely doesn't fit, i actually think i can just drill through with the 1.5mm bit, but I'm happy with the power delivery as is so I'm not going to fix something that isn't broken. Oh i also drilled a 2nd hole in the slide but smaller than recommended by procycle. I basically did everything the complete procycle kit does but i did it only half way, and half the results are fantastic!!! Especially given that it was for free,.... I got a 2nd hand dr with a very loud pipe but nothing done to the carb, there was a lot of popping on deceleration and it was annoying and that was the reason i fiddled with the carb i did not need more power but i do appreciate the extra oomph, it still pops now and then but it is a lot better. My brother had a completely stock dr and before i fiddled with the carb on mine my dr had alot more power although it rode alot rougher and the popping was horrendous. His stock dr was extremely boring to ride in my "hillbilly wannabe" opinion
