The “F” stands for front, so when installed in the engine, make sure the “F” on both pistons is facing the front of the engine. The “F” will line up with the exhaust valves on the front cylinder, and the intake valves on the rear cylinder.

 

thanks,

I am still unsure if i applied the gasket material correctly it does state apply to the outer edge of the crankcase and even has a diagram . but I'm not an expert and a little worried if i applied it right. there is mating surfaces inside the crankcase that I'm worried about.

Thanks again

 

if you applied it how the manual illustrates (shaded area) then the other area would probably seal with other assembly components.

 

True and that's the same thing i was thinking . however i can't find any gaskets for the other mating surfaces of the two cases .

Thanks,
For your help in advance
