Just waiting for mine to majorly break and warranty not cover it then either the Fuelmoto or a big Harley motor wet head.... so far the only go to 110 with the wet head on there website

 

I did the FM 107 CNC heads, woods 999 cams. Went from 78hp 97trq to 114.5hp 123.3trq. I have Fat Cat exhaust and FM air cleaner.. and the air was super humid in Little Chute, WI that day numbers will change automatically on the bike with better air (said nov-feb is when the best #'s are). Best bet is call Bob and discuss your options. But I will say I am happy with my results, and will eat 110's all day.
