I was out for a equipment check ride and seem to have loss top end. I have the usual mods AIS,Flapper, Open airbox, FMF Power bomb and Q4 muffler, and FMF programmer set @ 3.3.(1.5).8.4.4. The engine check light came on for about 5 minutes and I seem to have no W.O.T. I have it geared @ 13/43 Stock and can barely get up to 70-71mph and 8500rpm max; I had it gear up to 13/47 and have had it up to mid 80's previously. I'm suspecting a problem with the FMF fuel programmer (only 2 months old).
Anyone have any ideas or a similar problem or post that was corrected.?
