Well, I got 169 out of mine, but that was exactly what I was expecting. Dual highmount HMF, pc3r, small airbox mod, K&N, tre. No super trick tricks, but when I did it the bike had;
clean/freshly waxed chain
fresh oil change
40 psi rear tire
clean air filter, no oil
So basically it was running in top condition, I always keep it running very well. For comparison's sake, same dyno same day, two 06 GSXR 1000's, both bone stock, both made 155 rwhp.
