48 grunt level increase
 

Although I haven't posted much in awhile (too busy riding instead of posting), I still get many PMs about what is happening with my 48 (my PM box seems to stay full). Some have commented and righfully so that all I have done to my 48 has been cosmetic. Except for the breather, D&D exhaust, and the ThunderMax ECM, that is true. That wil soon change as I'm going to put a 1250 NRHS Stage II top end on the 48. Still deciding on the cam grind...but wil probably be either .536 or .551 lift...

Like to hear from others who have gone the NRHS route...thanks in advance
