After 9 runs on the dyno,I am running Truxston needles 2 shims.Bubs slashbacks,Freak box,K&N's,Nology IgnitonIridium plugs,Harley pitcock. The bike made 64.53HP & 49.41 LB.of Torque.Stock needles and 2 Or 3 shims I think would get the torque up in mid range..I just put a belt drive on it & I can't wait to get back to the dyno-the belt is 2lbs 11 ounces lighter than the chain.The difference on my bike is wild.It made the bike smooth and the control is a lot better...best money I spent. Just my .02 cents
