I have a 1999 yz125 just had a full top end rebuild. Took it for a spin up and down the street and felt like it was bogging everytime I hit high rpm you reckon it could need a carby tune?
If it was bogging then it’s most likely a carb issue, especially on a older 125. It could also be an air leak but that’s less likely. Also a rare case but if you did the piston yourself you could have put the piston in backwards. If you rebuild the carb I suggest just getting entirely new jets that are best for your area. Thanks for the comment hopefully this helped!
You ran it so early it sounds like the top end is flooding with unburnt gasoline from the crankcase. Be more gentle and go through more gears for at least 4-5 pulls 1/4-2/4 throttle and then try it again. Although it would take the abuse its not good for the engine, I always wait for the cylinder to feel warm to the touch. You also cold foul plugs fast when trying to rev and the engine "barbles"(dont know the word in english :D )
It’s always been a large debate on if you should warm up a Two stroke, some say you do others say it gunks up the carbs on the older bikes that have them, either way it really just depends on if you got the time to do so. The clips shown are also shortened and doesn’t show me propping up the bike while it idles to adjust camera settings. I agree sometimes you need to warm up a bike more than other times. This bike also had plenty of issues not focused on in this video and could be cause for the sound you hear, especially with the jetting on this bike. Thanks for the comment however!
If it’s rattling I would first check to see if it’s just the engine mounts are loose and the engine is shaking or if something is just shaking loose. Now if it’s a actual ticking sound you probably have rod knock or piston slap. I have a video where I look at the top and bottom end on a two stroke. It’s called “ piston slap or rod knock “ as far as clutch making noise it can happen. Mostly in Kawasaki you’ll hear some noise from it but I saw your other comment and it’s not common for cr to make a noise from the clutch. If you know the noise is coming from the clutch case area and especially if your clutch is still gripping good and it only happens when you pull in the clutch lever it could be possibly you have worn or notched fingers on the basket.
@@tommatthews5195 Alright lobotomite clearly you didn’t watch shit in the video💀. Literally diagnosed the problem and fixed his bike. the clutch was slipping and guess what bud you gotta buy a clutch to fix a bad one 💀 we’ve been riding several times after this video was posted and the bike works great. Thanks for the engagement though really helps me in the algorithm!

@@ChaseAbbott45 Yes sir, thanks for the big reply :)
Could you fix my cr 125 2003
Could my clutch be making my engine sound like a time bomb it rattles like crazy

@@ChaseAbbott45 ok thank you very much I have a short on my page if you wanna hear the noise yourself
It runs rich, smaller main JET or clean the carb
Definitely needs it
This is the worst advice iv ever seen, bro please don’t work on anyone else’s bike. I hope no one watches this and wastes money on a new clutch
