I've got an x18 that I recently blew out a couple gaskets and was wondering if there is a manual or a how to, to taking apart this engine..

I'm basically wanting to take the head and cam out and start from there. I'm not sure how to go about doing it, cause looking at the cam, I would have to take off the cam gear but then the gear and chain would fall into the crankshaft.

If that made any sense. I'm basically looking for a general tear down steps guide.

if you can find a clymers manual for a 50cc all the way to a ct110 it should give you the info to do the job
i used this my first time
make sure you torque the head bolts to 10ftlbs

np, gl
if you take the piston out, i would do the ring gaps in 1/4s instead of the 1/3s they show

Good question, I'm thinking its coming from the middle gasket of the engine. Its really hard to tell. All the gaskets look to be shot too.

If it is between the black cyld and the head, the head gasket is blown.
If you take the head off put the engine on top dead center on the comp. stroke, and don't turn the engine over while you have the head off.
Take the cam out, hold tension on the timing chain, pull it over the block or whatever, and tie it off so it can't fall off, that why it will be timed when you put it back together.

Its the gasket in the middle of the crank case. not against the head. I can take a picture if you want.

So, it is your crank case gasket then, can you tell where its leaking??
Might be able to clean it and seal it with a sealer.
