Re: Dyno following rebuild and mods
It does look a bit down on HP, a standard 929 should put out about 125 hp, and a Hindle system, with appropriate adjustments, should gain another 5-10. New bearings won't make the engine tight, how long has it run in for , and how did you run it in? did you do anything to the cylinder surfaces? I'd be very tempted to do a leakdown or compression test, maybe the rings haven't bedded in properly. First thing, check the airbox to see if oil/snot has been blowing in from the crankcase. I just rebored my 929 (to 954) and noticed signs of such snot from the crankcase when I checked it over after the first 30 miles. Now the rings are bedded in that doesn't happen. Did they give you a graphic of the air/fuel ratio? did you notice where it was at the interesting points? I presume you have a power commander fitted, if not that's your next step. And find another dyno operator.
