GZ 250 spewing oil and smoke.

SEGACDX · 09-04-2017, 08:26 AM

I bought a GZ 250 as a project for cheap used came with lots of extra parts, everything inside seems in good shape.

I recently re-did the top end with new gaskets and rtv thinking the problem was with bad leaking gaskets, it always smoked before I bought it hence why I got it for cheap. The amount of smoke is large and oil comes out the pipe black, the smoke is white, I've adjusted the tappets to .005-in they where all over the place before, I just wanted to redo them quick, I'll check my service manual and do them again very soon to the right clearances.

I am not sure what to try next, some say piston rings could be the problem but I'd like to hear what you all think could be the problem.
