I'm running one. 36* helix with a green spring in the middle hole. M8 (57/63?) gearing in a 08 m1000. I like it it has got the job done. But if were to do it again I might go with the old m7 style that you could tighten without pulling the cover plate and wrestling the spring to get it back together. The back shift is good and it shifts up and holds RPMs.
