What kind of oil did you use for the new cilinder? Just 4stroke oil?

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?
