I wonder if anyone here has tried to make a gasket as opposed to using a pre-fab replacement or silicone? When I removed the cover that protects the variator & clutch, the gasket came off in pieces and forgot to buy a replacement with the new variator. After much consideration, I decided to make one using roofing felt paper (already had a new roll sitting in the corner going to waste). It was easy to cut out, punched out the bolt holes using an ink pen and the shape looks identical to a manufactured replacement. I've done this before on a lawn mower carburetor mount & the gasket out-lived the remaining life of the mower for the next 5 yrs.

I do make some gaskets myself, paper or a Felpro exhaust gasket material, or RTV...
But I have not bothered to replace the worn and broken CVT cover gasket.

I ran mine with out the gasket too. I have also made a lot of my own gaskets though I always use gasket material. I can see how roofing paper might be a poor material for gaskets though it might be ok...

The 50cc Kymco I just fixed had trouble starting until I put the thick rubber CVT cover gasket back on.
But, but my Chinese 50 and 150 did not miss their paper gaskets.

That gaskets is not important or necessary at all...If you need all the other gaskets I think you can get the whole set for the motor for like $12  |

I think that the dimension change would be the only consideration for replacing the CVT gasket. If nothing is binding without it then I wouldn't bother. (I didn't) It's not containing any fluids or pressure. The CVT cover is mostly just a dust cover though it does provide some support on the larger 125-150 motors.
If you're so inclined, your local auto parts store can provide you with rolls of gasket material, (thick, thin, fiber, or rubber) for about $5.

I have made numerous gaskets over the years. But it depends on where it is being used though. But for the variator/clutch cover, it doesn't need a gasket. No reason to bother with one there anyway. Actually the only reason to need a gasket on the cover is if you need that tiny bit of extra clearance to keep the cover from touching something that moves on the inside.

The CVT case gasket does offer some protection from oil drips from the airbox/purg tube from getting into the belt case and provides some extra margin of protection from rain getting inside the case. I have left them off too on the GY6.
I do make my own gaskets when I can where they do not require precision die cutting and such but always use the most appropriate material. Roofing paper may work for some items however with its relatively low melting point, non-existant resistance to gasoline/oil and in itself being flamable I would not use it on an engine part or near the exhaust system.

I have made my exhaust gasket out cardboard ( over 500 Klm and its still as good as new ) have used many other types of materials ...ie rtv, cork, leather ...in the past when I restored bikes in the 80-late  's . |
