I'm having dramas with my Quickshifter. As soon as it gets up in the rev range its starts cutting out on the straights. That was on 85 sensitivity KT 60. So we lowered it in stages to try find a range it would work. Loom is fine and not touching the lever lol. We ran it at 10 sensitivity and it was fine, but obviously had to shut off to change gear. We ended up running it at 30 Sensitivity and that settled it down a bit, but still had to shift a little early so it would not cut. Have spoken to HM Australia and they have been great. But any help would be greatly appreciated.
