So then, I have a 99 Honda CR125 mx'r in the garage that I have up for sale, money, a mate with a welder and the idea of putting a large thumper in it for motard racing. I think cc capacity is limited to 700cc (will have to dust of my MNZ rulebook). Question is what engine to use?? ideas? the bigger the better!:Punk:

Agreed. Nice and simple engine, which isn't gonna blow up on you and is still fast enough.

Yeah, the shocker has it.. Port the bejeezus out of it. Don't settle for anything less than 90hp..
