Man thanks Hover. I tried everything except new seals and of course that's where the leaks were. It idles now. Much appreciated, my dude.

Thanks Mr. Hover, that informative seal leak vid. really drove home the importance of all 2-strokes need for a leak-free crankcase. I've seen several YT small engine repair gurus using a vacuum gauge & hand pump to verify leak free status before reassembling the chainsaw, weed whacker, etc.. Now, I see the symptoms while you describe them in real time, & your leak check spray diagnostic tool! Auto mechanics "spray" 4 stroke manifolds, carb flanges, vacuum lines, etc. to find vacuum leaks wherever intake vacuum might be, listening for that rpm change. Great teaching!👍

Ive always been afraid tho change my own seal, ive bought new bottom ends because of this. But tonight i changed the seals on my yd100 after watching this video

@@LAHover Hey there Hover. I got myself a problem and can't seem to find what's causing it but I keep blowing crankseals! I'm now on my third crank seal magneto side. Maybe the seals I'm getting aren't good enough? I find that my seal is blown in half! That is, they split right up from their middle diameter, splitting into a outring and inner ring. Do you have any recommendations for fortifying seals?

I enjoy your enthusiasm I'm new to the sport but I must say is a little carried away.

My bike has been running lean for a while now like where it shuts off at idol and it runs away, rode it at least 30 miles, no damage. I checked every single seal including crank seals, no leaks. I think I'm gonna replace the crank seals. Anyways because they are very chewed up, maybe I just didn't spray it right. Thanks for the awesome video man!

Alex from motored life showed in on of his videos that they make a seal saver for motorized bikes. the high compression motors put a lot of pressure on the magnet side because it’s smaller. It’s a piece of metal that screws in under the magneto so it can’t pop out.

Great video bro!

I live at 4600 foot elevation. Mine was running to rich so I moved the clip up to the second notch from the top. It was then running perfect except at full throttle. So I ordered jets. I got the wrong jets, so I put the carb back together and back on the bike. Then it was running to rich again. Apparently I had an air leak at the carb mount that I fixed when I put it back on. I moved the clip to the top notch and it's only running rich at full throttle. Now it idles much better. The correct jets are on the way.

I took off my engine, because of a leak and blow out around the muffler or jog but can not tell but I will try the starting fluid

Do you have another link I could use or could I find this at my local auto parts store? I just want to make sure I get the right size, I'm pretty new to these engines and I have an air leak in the same spot. I have a Zeda 80 Firestorm.

I thought it was a leak in my 212cc bcuz it was only running with choke on so I changed to a bigger jet and it runs dope now💯✨✨✨✨✨✨

You know I was thinking about it and I think I might have the same issue thank you

@LAHover

Good luck on your build, easy fix. Just make sure you don't push the new seals in to far like I think I just did lol...

My bike does not idle or start well when it is not choked. If I get it a bit above full choke, it starts and idles properly. Does this mean the seals with the carburetor are the fault?

That's a good one, personally I use for the crank SKF 6202 TN9/C3 and for the clutch 6202 2RSH/C3 the crank seals the chinese ones...

I thought my idle didn't sound right. I was looking for examples of a correct idle on these motors and I think I finally found it here. My bike idles fairly high and soft and it takes ages for the rpms to drop. The revs drop somewhat faster if I unscrew the idle screw, but then the engine dies if I let go of the throttle of course. I got it to idle better at some point, but I feel like it's gotten worse again. Funny thing is I ran the bike for about 400-500 km already and it seems to run alright. I had the feeling it was running a bit rich though and I found a fairly good spot with the stock jet with the needle at the leanest setting. People tend to say the stock jet is fairly rich so maybe that compensates for whatever problem I have. I was also running very oil rich for maybe the first 200 km and I didn't exactly go soft on it during break in, so now the piston top is really black and it seems there's been blowby happening too cause there's smears under the rings, lol. Well, replacement isn't too expensive. I just hope the eventualy failure won't be catastrophic.

what oil did you use to lube the middle of the seal?

What exhaust is that it sounds crazy good

Whats the jets you ended up using on the pz20?

Where did you get the handlebars

Mine yesterday was running at a very high idle. So high infact that when comming to a stop I chose to not pull the clutch and let the engine slow me down. I know that doing that can fold the chain up but was scared the motor would over heat. Think that my head gasket isn't sealing all the way.

All tuning should be done on a 'normal operating temp engine' Cold means nothing you don't spend most time riding on a cold motor. These carbs have no auto choke and/or no choke at all so it should not idle well if at all when the engine is cold.

what kind of starter fluid should i get

Hey guys, My carburetor is leaking gas from the cover area which i think is called a float. Its the NT carburetor with the red cover. I checked my donut it has no holes and it wasn't stuck. Any advice?

hi i get mine started by poping the clutch but then it dies after 10 seconds like the engine doesnt start burning gas or maybe no spark but also the engine never clicks to be able to start it why doesn it click?

You have to modify the pipe to get it to fit?

Here before 100 views!

I had a marine bike everything was good until I hit a pothole breaking my seat post after that my engine started to destroy itself because of so much vibration the drive sprocket loosened and the chain keeps popping out.

Thank you.

Could you please remind me what bottom end are you using? Is it a PK80? If so, may need to buy some. I have a brand new PK80 Zeda FS, and she was leaking. Tested for leaks, but not the seals. Too late though. Seat stay bolt snapped, and I botched the repair. Happens when you’re over tired and think you are able to get the job done. Lol. Will need to replace right half, and might as well change the seals while at it. Attempting to JB weld and tap a new 8mm thread…for science sake. Lol. Thanks for the videos as always.

That's great that you got it fixed.So we all aren't 'searching' for hours,what grease did you use in the seals that won't harm rubber?I used Molybdenum on all the steel parts,including cables before putting them in sleeves,and spray Silicone on rubber,but haven't considered a grease for the seals.Thanks in advance.

awesome vid man!!

I wish I could figure out as to whether or not my bike can even idle because the second I come to a complete stop the engine is or has been completely turned off way before then maybe my clutch isn’t tight enough or perhaps I’m nowhere near done the buildbecause everyone talks about the two-stroke being able to just idle and sit there to heat up which I would love but mine does not really do that. It’s either move at full speed which is a 20 to 25 miles an hour or nothing which makes turning around or doing a quick U-turn in a small space very difficult, because I have to return it on every single time.😂 One issue that I think would help fix it is having an actual level intake because mine is at quite an angle right now working angle, but not correct angle light level, for example😢

Man I just put mine together I just had to order a new CDI when I take the spark plug out it sounds like it's doing what it's supposed to when I put the spark plug in it barely making any sound at all

Exhaust pipe link?

i think my yd100 needs a new seal. it is consuming too much gas and it's kind of weak

Start by swapping out a new carb. For the price keep a spare ready. If that works, you've wacked off half your variables. More. Then see what kind of tuning you have available. To keep from recurring get the ethanol out of your gas (easy) - and switch to a full synthetic oil and lighten up on the lube - max of 40:1 per the label. The ethanol is more trouble than it's worth - and cheap carbs corrode into aluminized jelly within hours - completely a non-starter no pun intended. If the new carb doesn't work - you're up.

Will those seals you linked fit a YD100?

I have exactliest this same McProblem on my mystery engine. I built me a trike a couple of years ago from a Schwinn stingray chopper, and a Heastrom 24" trike. And I've been fighting everything ever since it seems. Until now it just flat won't start at all! I've had to replace the CDI from a stage II and a coil off of a little 4 wheeler to a mystery coil. Then to the stock CDI coil combo. Had the headgasket leaking so I built one out of copper. Got so frustrated with the whole deal. I pulled the engine and decided to go 4 stroke. So after cutting half of my frame out to mount the 4stroke over the axle. It sucks. I hate it. Can't keep the (mouth full of cuss words ) chain lined up. Turned my whole build into An abortion and now I've given up hope and I don't even care anymore. I quit!!!!!!!!

That intake is definitely effecting the performance.

And for the phantom owners beware the heads suck they never sent me Emmanuel with my kit and the break-in I guess it's supposed to be 20 to 1:00 and then whatever comes after 20 to 1:00 you're supposed to be running them at now my phantom yesterday blew up cuz I was running 35 to one for breaking and then went to 40 to 1:00 soon as I went to 40 to 1:00 the nickel plated came off a chunk of the aluminum busted and destroyed and I mean destroyed the the piston and the cylinder
