Isn’t it worth putting a Japanese piston an rings in , I used to get bikes I had 4 Yamaha DT125R, an I was always told make sure you buy a Japanese piston , about 20 years ago I ended up buying 4 Yamaha DT125R, made one faster than a YZ
Hey man I have a similar pit bike, the kick start only goes down if the clutch is held in but has no compression when it dose kick down just goes straight down. If clutch not held in it doesn’t kick down just stuck, if you would know why like it needs a full rebuild or worth fixing would really appreciate it I can’t find any information on it. If u don’t know that’s okay man
Someof these little bikes will only kick with clutch out. When clutch is in it does not engage. If yours isn't turning it could be stuck or seized, can you roll it in gear?
So I took my dirtbike mudding and in the middle of the mud my dirtbike turned off and hasn’t started since I took my whole dirtbike apart dumped out all of the gas took my nibbi carburetor off cleaned it and I took my engine off and took the engine apart drain all the oil and then I put everything back together put new oil in it and new gas and it’s still not starting and now there’s something leaking out of my bike and idk what it is and it still won’t start and it has compression but not as good as it should do you know any reason why it wouldn’t be starting still or what would be leaking out of my engine?
Cool project i would love to have a pitbike

Is this a dry or wet sump?

You saw in the Video it was the cdi
how could you not see your fuel line is kinked
where did you order the piston from?
Aliexpress diameter was 52.4 mm i think
What if I don’t have a way to hone the barrel
Use 800 grid sand paper
Buy another one there like 20-30 quid
Where did you get a piston for 10 euros??
Aliexpress
if you dont mind me asking how tall are you
He sounds Dutch, So probably pretty dang tall
what size is that piston ? and won’t the compression change due to different depths of the piston ?
It’s bogging when you rev it wide open check the valves and clean the carb out
Ik hoor gewoon dat deze man Nederlands is
I had one jst gotnit
And it blew up after the second time riding it
I’m lowkey a bit pisses Idk what happend it was riding good until I shifted wrong then turned it off then it blew up
It's still chugging oil😂
he missed the oil ring on the cylinder
😂
You got the wrong piston they make a big and small valvle of those motors think you got the low comp piston
Might need new oil gide valves stop that smoking
