snowbyrd. i ride at 3000-6000' and i have the cutler secondary conversion kit on my 07 M8 snow pro with 73gm weights and it made me gain almost 300 rpm, 7950 from 7700 when i first tried it out. now i havent had any more time lately to mess with it. i have also messed with another guys clutch conversion kit from OVS it is more or less cloaser to the RKT kit. and in his situation he also has some excess rpm. now loosening the torsional pressure in the kit should bring the rpm down a bit however i am in the mids of throwing 75gm to my primary to see if my motor can pull it with this kit. i also have some SLP MTX adjustable weights on the way so i can load up the tip of the weight a bit to try and achieve a better final shift out. i would suggest adjustable weights for avid tuners they are usually about the cost of 2-3 sets of weights witch i think justifies the cost for the range of weight and tuneability. ill get back to you further once i get some mor play time. and if your putting a performance head on your going to gain rpm with the gain of power so you will have to throw more weight at the primary another good reason for the adjustable weights.
