Im runnin the stock 07 throttle body and it works fine.

Its been almost two years now with the stuff in my sig.and i just made an appointment with a well known tuner to have his way on the dyno with my bike,cant wait to hear what he says and the results.

 

The '07's have a 48mm throttle body. Those really respond well to porting.

 

This not a good combination. Your ccp will be too high. About 210 with the 10.5:1 pistons. I just took my 255 out of mine. Tuner explained the combination need to calculate out to be around 180 for the best tuning. Changed my 255 after lifter failed and put in Andrews 32 to match heads and pistons and got ccp down to 187. Real compression dropped from 245 lbs down to 208. Bik runs much smoother now
