Wondering if someone would be able to help me out with a detonation problem. Just put a 103" kit in a 2000 FLSTF. It had major detonation issues after the build and dealer recommended the Crane Hi-4TC so they could adjust it out. Bike has great seat of the pants power but it still pings when running at highway speeds in 5th gear and giving it 1/2 throttle or more (like when you want to pass). No problems at idle or lower RPM's only at higher RPM's and giving it 1/2 throttle or more and then only when you give it throttle from a steady speed like 70 MPH. If you are getting on it and rowing through all the gears it doesn't have a problem. Anybody have any suggestions on what I could do to the settings to get rid of it? I'm already running 91 octane and these are the current settings: Mode 0 Rear Cyl 0 Initial 0 Advance 1 I was thinking about taking the advance down to 0 and see what happens. It doesn't have a problem at lower RPM's and idle so I was thinking only going lower with the initial if moving the advance to 0 doesn't fix anything? I've had it back to the dealer twice and they say they can't get it to ping when they ride it so they can't make any adjustments.
