[QUOTE="motometal, post: 664797, member: 24727"] 13/50 is my favorite also. I've wondered if 13/51 wouldn't be even better for tight tracks. But remember, 1 tooth is only 2% on the rear, so you really need to move it 2 teeth to make a significant change. If the bike doesn't seem to rev out properly, is the main jet lean enough? If you happen to have the stock main jet, you may try leaning it, but I recommend running at least 50% race fuel to be safe. [/QUOTE]
