i got a mark on the moveable sheave of the primary right at the top but it only goes about half way around the clutch which i thought was weird. and if it matters im running the stock yellow white primary spring, m8 orange sec. spring with shift assist and stock 36 helix.
as for the weights, i bought them when i was trying out some twins which required lighter weights so mine are the ones that range from 60 to 70 grams. i don't remember exactly which screws i have in them, im pretty sure the second to the longest and maybe the 1/2 inch one, i know between the two in the heel and the little one in the tip it was right around 66 grams.
i know this might sound light as stock the efi m7s run 68g but mine is the carbed version which comes from the factory with 67g plus my sled is geared down two sizes from stock and ive heard that sometimes requires lighter weight. motor wise my sleds stock with a RKT modified stock head and i ride 6-9000 ft.
im gonna try pullin the small .75 gram screw from the tip and throw the next size up one in and see what happens. i know with the current setup my sled will kill both the efi m7s in my group out of the whole and pulls like a whole different sled, i just gotta get the wide open thing figured out.
