alright i have an o5 xb9r with a ti-force exhaust and a tfi techlusion. if i rap the throttle in reall hard like tying to go as fast as i can it will pull hard and then stumble almost like the fuel is cut and then it misses and shakes until i let of the throttle and then it is fine. If i roll in smooth onthe bottom and then punch it it pulls reall hard till just above 5000 rpms and then cuts again ..what the hell is wrong with my bike. i should be able to gun it no problem and that is way before the rev limit. help please.

i am thinking maybe the tfi is off and it needs to be dynoed and adjusted

Yellow,
first thing to do is put the 1st, 2nd, 3rd pots on the tfi to the 1'clock positions...turn them counterclockwise...put the 4th pot on 7.5 o'clock and ride the bike between 3 and 4000 rpm for a while and give it time to learn....let me know what you get after you have put several miles on the bike...don't get in a hurry, its easy to tune on the road....
