Today I assembled the engine back together putting a new gasket between the cylinder and the crankcase. I used a thick one, applying a bit of red gasket maker on both sides of the gasket. I torqued it to 10 pounds and cleaned everything super nice with brake cleaner. Tomorrow is going back. Wanted to let. you know that I blew air through the intake with my mouth and the air does not go anywhere, meaning I guess, that the inner seal is still holding. I also convinced myself that somebody ported or did something on this bike to make it faster, the rod that moves the piston has a lot of steel removed on purpose. No wonder why this thing is much faster than my Ciao. Regards!!!
