901 big bore am I the only one??

[ScottPruden]

Have a 2010 m8 with d and d big bore 163 usually ride 6-8000 feet. Sled finally running good looking for some clutch starting points. Cat gold primary spring, 36 stock helix , also tried a torsional 38/36. Thinking a 42/36 might be good to try what you think?

I tried a 42/36 with little luck but I have heard the 38/36 torsional set up works good. I currently run the 36 and the sled works like it should.What i found to help on mine is a softer secondary spring stock orange is 175/280 and i went to a 110/260 easier on belts and lower clutch temps you may have to run more weight than before though. I do not run a 901 big bore but a M1000. Hope this helps.
