m7 only hitting 72-7500 rpm ??? any suggestions
heres the dealio, ive been playin with clutching a bit lately and heres what i have currently cat gold pri. spring, stock 67 gr. weights(carb model), 42/36 progressive helix with orange m8 spring and shift assist. i ride between 6-9000 ft, and sled is currently all stock with a SLP can. i love the low engagement of gold spring and the pull it has off the line with the 42/36 helix but im topping out at around 7500 rpms and have seen it run as low as 7200 on some climbs. however even though it is only turning those low rpms it is still pulling between 35-40 mph track speed when climbing and still hits over 75 mph on the trail and the clutches are fairly cool. i guess my question is what would be the easiest way to get the extra rpms without effecting my setup in a bad way. lighter weights? how much lighter would i need to go? maybe a spring with a stiffer finishing rate? i ran it with the stock yel/whi spring and it pulled 75-7600 rpms pretty consistantly, just no sweet sweet low engagement which if need be i can do without. im pretty sure its the steeper helix thats loosing the rpms but i like the way it feels. oh well, thanks for any suggestions.
