My friends Gen I runs fine in every way other than Rev limiter cuts in at 5k rpm. Any thoughts??? It was fine but just started doing this about 2 years ago. Approx 120K miles on it now.

Only mods are Air Box and PC 2

Already checked : Oil, Power commander, plugs, Throttle adjustment and positioner, air filter changed, fuel filter changed, all cylinders have correct compression... just hit rev limiter at 5K : pop-pop-pop-pop-pop ...

Thanks - Kento
 
Where's the idle set. If it's really low that could be your problem. Otherwise replace that fuel filter and run some seafoam thru her
 
I think he said he did change the fuel filter and emptied and cleaned the tank, I'll check, thanks guys.
