2 weeks ago I was seeing 95mph on the digital readout (on a fairly short run) and now i'm only seeing about 85mph. The other night it was 77mph max.... no problem.... removed exhaust valve servo cover and reattached cables. Added small spacer to prevent this from happening again. The only thing that has changed is I had reverse installed , but I'm pretty sure i had this problem before reverse was installed. Loosened track, removed thick shim from secondary and reset chain tension. RPM is at about 83-8400 where it always has been. Going to try a new belt tonight and will switch back and forth between analog and digital readout to see if there is any differences, but if anyone can think of anything else I would appreciate it. Wouldn't be too concerned if i hadn't already seen 95mph on digital readout?
