I have leaked oil on the front of the main cylinder head and from what I can determine, it is coming from under the cylinder head cover, more from the left side.
I assumed there would be a gasket between the head cover and cylinder head, but evidently there is not??...does this mean the cover has warped and needs to be replaced?

My bike is a RYCA kit re-build, so the chrome top covers were removed, with the long bolt on the left front cover was cut off. That bolt does not appear to tighten the head cover down, just used for fastening the top cover. Correct?

Any help will be greatly appreciated!!

With a bolt every few inches, I doubt it was intended that the cover would be stiff enough to warp and cause a leak.  That said, a missing bolt could cause a leak... replace it with a shorter one.  While there's no gasket, there's RTV.  It was probably thought to be to complicated to seal properly.

But, 1st things 1st, clean, go for a ride and confirm where it's leaking to avoid doing unnecessary repairs or doing it twice.

Thanks NJ Gary & verslagen1.

re: RTV...recommend a brand?

thanks Dave...and appreciate the link!

Rubber gloves that stuff sticks to everything and skin !
If you are going to reseal head cover don't forget to do the head plug while cover is off , buy one from Versy

Thanks guys...
