Xr 80 1985 valve timing

Recommended Posts

Can anyone help. Xr80 1985.I put new wisco  piston with a rebore.   Would start with a push but not kick start and ran lumpy and would not idle.  I checked the timing on the points and they start opening at the f Mark. I checked the t Mark against the small cast triangle so should be Tdc. But checking the piston it was not Tdc?  Could the fly wheel be off a different bike.  Only problem Is when I thought I had solved the issue I changed the chain and sprocket position and I think the piston touched the inlet valve when the engine was turned over.  Does this mean the valve will be bent?  Any advice
