THE RIGHT WAY TO ADJUST YOUR PIT BIKE VALVES
HTML-код
- Опубликовано: 8 сен 2024
- In this video I work at troubleshooting a pit bike I bought starting with adjusting the valve tappet clearance.
This method applies to all horizontal engines for small dirt bikes and atv's.
Intake clearance should be .003
Exhaust clearance should be .005
For the best cheap feeler gauge : amzn.to/2UhgkQV

Nice you actually showed the valves on camera. Nice to actually see it and know where they put the feeler gauge. It hard to tell what they're actually adjusting on a lot of other videos cause they dont ever put the camera on it. Thanks for the video.
I know exactly what you mean. That’s why I made this video 🤣
Yo this is the first video I've seen where someone tells me how to take the cam gear cover bolt off haha top job brutha
Thanks man, glad to help
Thank you! After hours of messing with my carb I have finally got my bike running perfect. It was the valves all along 👌🏼
Awesome glad you got it fixed!
Have u ver set them to 00.3 - 00.4 ? For a yx 140?
Good luck with getting it started!😄
I finally got it. Head gasket! Turns out the transmission was shot too
that's funny I have never seen another monster Joe ... I have this exact bike and am always adjusting the valves
The little keeper key were the flywheel sits on the crank by were the starter is you can make one out of a nail
I had a 150 konker made that sound were carb went on was warped
Hi, not sure if you'll see this in time but I'm actually following your video right this minute, adjusting the valves on an Apollo dirt bike. But I'm at the part where I'm doing the exhaust and when I opened it oil started pouring out, and it's actually still pouring out, there's a lot of it and its continuously pouring out in a very thin steady stream. Is that normal?
Also Your video is very easy to follow, so thank you!!
Don’t worry! That’s normal on some of the Pitbike engines. The oil lubricates the top end and usually drains back in to the bottom end but on some models it will pool there. Make sure you check your oil level after you get it reassembled
I have a thumpstar 140 pitbike, bought it used. air filter is clean,good spark, good fuel,its getting fuel & will kick first start and idle and rev fine so I know carb is okay but after it warms up and u ride it for 30 secs it bogs out and shuts off and won't start till its cool again. Acts as if its suffocating for air or something.. Usually takes a few mins to start back up.. Do u think the valves are getting too tight once its warmed up and causing the issue? Hope its a simple fix. Plan on tearing into it later
Are you getting enough fuel flowing into your carb? Maybe your fill plug is clogged and not let fuel in fast enough. It doesn’t sound like a valve issue to me.
@@burnout_MEDIA it was the fuel filter. Easy cheap fix. Partially melted lol
Head gasket is actually a really easy fix on that motor. Should be straight forward the hardest part would be the timing I think
Yes it wasn’t bad at all!
Thanks very much
Glad to help. Please thumbs up and subscribe!
This was my bike at one point lol. The ripped seat blue gas cap messed up flywheel cover I have a video of it running if you wanted swear to God its my bike. I traded it for a atv from the guy your probably talking about that you got it from. Did you get it near or from lancaster pa
Yep this is it. I didn’t get it running and found out the transmission was blown too. Piece of junk. Wouldn’t deal with that guy again.
You got spark ? Yep ... you got fuel? Yep ..... do you have compression??? That should have been the first thing you checked. And that skweeking sound ? Probably your crank bearings.. I can’t say for sure but I’d put money on it Long story short,, The guy that sold you the bike well he got you. It’s an easy rebuild or Change out. Either way it’s better than junking the bike. Good luck to you
It was the headgasket
Hi I think my head gasket it leaking too where would I get a new one is there a link?
What size engine?
Jason Garber Chinese 125cc 4stroke
My kickstart is super hard to kick and it pushes back hard on a fail attempt, too much compression or bad valve timing? Thanks
Sounds like bad ignition timing
@@burnout_MEDIA If I keep starting it without fixing the ignition timing will it harm the engine or cause it to seize? thanks for the quick response.
@@chinosaki8067 does it actually start? If it starts and runs ok then it’s probably not your ignition timing. What kind of bike?
@@burnout_MEDIA it starts after a few kicks. Runs and idles smooth. I have the Apollo z20 max brand new 2 days old. Majority of the time it’s hard to kick at the top, I can put my full weight on the kickstart and it won’t go down. If I try again but with force it will move.
@@chinosaki8067 sounds like it just has a lot of compression which is a good thing. Kick it like a man!
So what causes the squeaking noise? I have the same problem
It turned out to be a blown head gasket
@@burnout_MEDIAdid you get it fixed?
U have intake leak
Does adjusting the valves give the engine more compression?
It shouldn’t, unless they are really really bad
Yes it will
U relaesd the inner dolphin 🐬
Lol what
Funny but makes no sense 🤣@@burnout_MEDIA
Did you ever get it going?
Yes. Replaced the head gasket and it ran like a champ!
did u fix it
Yes it was the headgasket
Looks to tight to me
