bolt seals
 

So I have the Znen variant of the GY6-B motor that has two bolts thru the cam cover. Does anyone know a source for the seals that go around the bolts thru the cam cover? Not the type with 4 bolts around the outside.

I didn't find any, other than buying a whole valve cover/gasket set for 40 bucks. I'd do some measuring and go see what I could find in the plumbing dept at Lowes or go to an industrial supply and see what they have that close enough to work. You might have to work on whatever you get some to make it work but that's what I'd do. Neoprene is Neoprene. Make what you need if you can't find it.
