a 48mill is not to big for a 650cc engine, especially if you want to feed the engine large quantities of ALKY (and maybe a tad bit or nitro[img]i/expressions/face-icon-small-wink.gif[/img] ). I ran dual 39mm mukunies with stock valves and I never had a problem with being too rich, and I was jetted as bout as fat as you could get.(10 passes and the tank was empty).
For drag racing on alky its almost impossible to choke these Rotax engines.
P.S> Jeff, i believe its the BIG BALLZ that gets you to the end first!

Bigger,
Thanks for the info. A lot of guys have been asking me how big is too big for the stock motor.
