i was wondering if this muffler and the air box mod where you remove the snorkel will need a fuel controller? Plus is stock clutching ok? Ten extra hp. Would be nice if the muffler isn't loud. I heard a clip of the Ulmer racing quiet muffler and it sounded good from ideal to WOT..thanks in advance for any input.

Allan can answer the fuel question, stock clutching will hit the rev limiter with those mods. You will need more weight or a clutch kit.

A fuel controller is not needed. You will need to do some clutching. Give me a call or email me and I can take care of you.
