does anyone know of a big bore kit for a Rotax series III 800 twin motor???

we have a few spare...scored up cylinders sitting around and were wondering if there were any big bore kits or whatever for it.

Cudneyracing does a 830 kit & from what I have heard it works really good & very reliable. Check out www.cudneyracing.com for more info on it or send them an e-mail. Bill Cudney is a great guy to deal with. I have bought many things from him & had no problems
