just had a power run done to my bike at Steve Jordans out near boxhill, and was wondering what sort of bhp anyone else was getting out of the same model bike?
mine is fitted with a titanium akraprovic can and it dynod at 120.82bhp
it was running very rich so its going back on tuesday for a remap, which should squeeze out a couple more horsepower.
I had my K4 750 dyno’d twice, on different machines, but both were the latest Dynojet 250i machines. The first run was to map the power-commander and produced 137bhp at the rear-wheel, and the second was 134bhp a few months later. It had a stage-one tune, i.e. BMC race air filter, fully synthetic oil, power commander (custom map) and Akrapovic carbon exhaust. Additionally it was also running a 520 pitch chain and Supercorsa tyres. The second time it was just to check everything was still running well, and so it was, though it was down on power by 3bhp, but there’s always give between dyno’s, even corrected ones.
The engine was run in hard, but maintained more often than the service book required.
132 bhp on my k5 750 at PDQ. It is the same engine as the k4 though.
spec is Yoshi tri oval can, BMC filter, 520 chain and power commander. The custom made map only marginally improved the power about 1 to 2 HP through the rev range but more importantly cleaned up the power delivery when the throttle was opened, getting rid of most of the jerkiness. As Jay says the dynos do vary, but you should still be looking nearer the 130 mark Surprised yours was only showing 120 BHP, it didnt feel underpowered when i rode it.
