i know i dont have much done to the bike yet but here is my stuff so far and my dyno numbers. Mild trail port, 4 mil, T-5's, K&N clamp ons, 35 pwks. my numbers were 44hp and 31ft lbs. i just got a pro design head for 70 bucks and i am going to get a chariot timing plate and v-force 3's as soon as my bank account allows it. and also i thought that those carbs were overkill but my builder recommended them.
