I finally built a tank out of aluminum. Works fairly well I did loose some capacity and I had to insulate it from the heat of the engine but, I'm not fighting the leaking petcock mount.

So I purchased a Beta Rev 50 for my grandson, he was on a TY80. Although the Beta is lacking in power the brakes, weight and suspension more than make up for it. I was wanting to big bore it just to help out the low end. Has anybody found a kit or a solution to the lack of low end on these bikes?

Can you replace the jug and piston to a 80cc? I would like to try and get a little more grunt out of my 2004 Rev 50 4 speed. Lowered the gear ration but now its too slow

I have a 2002 Sherco 50 and the fuel tank is leaking. I tried patching it with epoxy, fiberglass, fuel tank repair, and even plastic weld it and the best I could get was about 3 months use then it starts leaking again, I tried to buy a new gas tank here in the United States but no one has one, So I'm giving a shout to you folks in Europe to see if you can help, PLEASE Does anyone know where I can buy a fuel tank for a 2002 sherco50?
