davemhughes said:On my last 95 build for my fatboy (not current one) I had it dyno'd and I had 104hp / 105T. I wanted the bike to be a little quicker off the line so I pulled the 32T front pulley off and put a 30T front pulley on. I then re-dyno'd the bike and had 101hp/103T. The dyno kid that did it said lower gearing or changes like a 30T front pulley result in lower dyno numbers on a dyno using rear wheel measurements. My question is: is this true???

3 hp/tq are within the tolerance of a dyno anyway
