08 M8 primary clutching

[kris.fancey]

I have a M8 with d&d head kit, y-pipe, monster pipe, mbrp can, & bdx intake. I'm wondering about primary weights. I have a orange spring & d&d magna force weights but dont know what kind of weight to run (grams) when riding around that 6000ft range. Let me know what kind of rpm i should be pulling at even would be a great help.

Thanks Kris

A set Cat weights in the 70 - 72 gram range should get you close, depending on what you are running in your secondary. Most single pipes on the M8's are looking for 8000-8100 RPM.
