What's your riding environment? ...cruising/touring/drags/roadracing -?

I've run the GSXR cams quite a bit in my 1216 Bandit... they run well anywhere in the 105/105 - 104i/106e - 102i/106e range; keep an eye on piston-to-valve clearance if you're going for an early intake opening.

-1157cc x 11:1, mild pocket cleanup on the stock B12 head/valves, 38mm CV's, GSXR intake cam/B12 exhaust cam @ 104i/106e, aftermarket 4:1 system- 135rwhp

-1216cc, 10.8:1 JE's, same head as above, RS38's, both GSXR cams @ 102i/106e- just over 150rwhp, torque around 86ft-lbs

Good grunty combinations for a heavy bike like the B12.

Oughta run great set up that way, with good power on top.

The 36mm CV's will have no problems feeding up to about 150 horses.
