I would get a PC. Right fuel map will make a big difference. Don't think you can download a fuel map for that exhaust. Last time I was at the dynojet website there was a 2 bros. and a akra map available. Hesitation is probably caused from running too lean when you get on it or certain rpms. I have the akra exhaust with a PC. I can't say I feel hesitation but sometimes it feels like it doesn't wind up quick enough in the low to mid rpm range. Once I get above it, smoother than stock exhaust. Maybe lowering front sprocket to a 16T would make a difference.
doood that's awesome, looks great!!! it also makes the bike look mean. I am having a hard time finding the seat cowel for that bike? tell me does the seat cowel just clip in like the rear seat does? and to pull it off you just use your key to unlock it right? I can't wait to get mine and the akra exhaust on my bike!
