I installed the Boyesebn Quickshot last night, and I got one thing to say----DAMN!!! Now I had to drill the screw holes out a bit to get it to fit right, and I was a bit distrought about that. I couldn't test it out last night due to the fact that my wife and kids were asleep. So I kicked it over the first thing this morning. First kick and it started like usual. Once that big b*tch was warm, I rolled on to the throttle and waaaaaaaaah----no hesitiation at all. The first second you give it throttle, it responds like baaaaam. If you aren't holding on well when you roll onto the throttle now, you are gonna have to go find the bike when you're finished dusting your arse off. Yeah I was pissed when I had to drill the holes out a bit, but the result was worth it.
