I don't think gearing is the answer (stock is 13/48, and judging by the pickup out of tight turns I think mine needs a 49 or maybe even a 50). If you want more rev I think you're on the right track. You may want to rethink your statement that jetting is fine... I think there's room for improvement, to say the least. I just rode mine for the first time yesterday, and it is way rich on the bottom, to the point of blubbering a little. Maybe the main is fine, but I'd at least try juggling brass before I spent a bunch of money.
