I have a 09 m8 sp with sw y pipe, jaws can, v force reeds, 4" intake, cutler adj weights, rock rollers and shift assist. most of the riding I do will be at 5 - 8000ft. I was wondering if anyone had any advice on a good clutching setup. Should I add any weight to the toe or load it all in the heel? Also are the stock primary and secondary springs good to go or is it worth purchasing aftermarket ones and would I benefit from the 10.4 secondary sheaves. I should add that I do some riding around 3000 feet and was hoping to be able to just add weight in the primary to compensate. Thank you in advance for any help!
