Personally, I'd try to get a pipe that isn't too hot to rejet because of. Be careful...just like adding a 4 barrel carb after 70,000 miles on a car, you may end up blowing the engine if the pipe is too hot. The Fuji 488ccF was a good engine, but change too much and you'll (almost) certainly have problems. That not withstanding, I'd consult (as I ALWAYS say) yea ol' Clymer's Guide to see what they say...
