I have a 2009 M1000 and I am going to put on an RKT head, just wondering what others are running? I ride 3-6K and was thinking about either the 13.6-1 or 14-1 head from Kelsey, I plan on running 20% C-12 with it. The sled also has a full D&D exhaust and a BDX intake with Boondocker box. Also just curious if anyone knows the stock compression ratio on these sleds?
