- In this video i am rebuilding the top end of a 125cc pitbike. Iam installing a new piston. and iam shoeing you how to do it yourself! I also show you how to hone a cylinder. and how to rebuild a 125cc pitbike. the brand is YCF and the pitbike model is YCF 125cc lite. this is one of the cheapest pitbikes i ever bought.
Cool project i would love to have a pitbike
Great fun
how could you not see your fuel line is kinked
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
what size is that piston ? and won’t the compression change due to different depths of the piston ?
Nice bike and repair !!
where did you order the piston from?
Where did you get a piston for 10 euros??
What kind of oil did you use for the new cilinder? Just 4stroke oil?
10w40
Ik hoor gewoon dat deze man Nederlands is
Is this a dry or wet sump?
Wet sump
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?
You saw in the Video it was the cdi
What size are the bigger wheels and tires?
I think 14 inch in the back 17 in front not 100 sure
It’s bogging when you rev it wide open check the valves and clean the carb out
I had one jst gotnit
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
if you dont mind me asking how tall are you
He sounds Dutch, So probably pretty dang tall
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
