I had my motor rebuilt on a 2006 Classic by a company in the mid west and got it back, installed it, got a break in map from fuelmoto (awesome guys to work with) then after break in had it dyno'd at my local Harley shop here in Salt Lake. Since I was doing a complete re build I had it punched out to a 95 cube, they also put bigger intake and exhaust valves in the heads along with longer valve springs and a set of gear drive Crane cams 1-3005's with a .619 lift. The problem I'm having now is that there is a quite noticeable stutter/miss with the throttle at the 10 to 15 % open position that can not be tuned out by the shop. I'm being told by my local shop that the cam is way to extreme and the builder is claiming that my problem is a tuning issue. I have a master tuner on the bike with Vance and Hines slip on's. Any ideas this stutter/miss is driving me crazy?
