I have a new Crossfire 800 and took it to the mountains. It only turned 7600 and have less than 200 miles on it. Only mods to it have been a D&D can and put 65 gram weights in primary. We were riding from 8-11K feet.

What changes do I make to increase rpm to the 7900-8000 range? Increase preload tension on secondary spring a couple of holes? Can the weight of the primary springs being too light...(65 vs 68) affect the rpm?

No clue on clutching as you can tell, thanks for help........
