Dont forget its a Fuchs Dyno, not a DynoJet one. From what I hear the Fuchs is more accurate, so produces lower numbers.

Not necessarily more accurate, just that it works in a different way

Dyno's are funny old things anyway - there are different compensation factors that can be used, according to altitude, temperature and humidity, then (as Jamie pointed out) there are different ways of recording the power - EC, ISO, DIN, etc., so you really need to see what you are comapring before making to many sweeping judgements.

I've been looking for the readout of my bike from Dynomaps Dyno about 5yrs ago, where it showed about 124bhp at the rear wheel. The bike hasn't changed much since then, other than a few more miles on it, but if I remember right the graph is pretty similar

i had a best figure of 107.9 for the zx6.
Very happy with that

have a pc3 to go on it as the only downer was a bit of a dip in the torque between 5500 and 7000rpm.

Well thak you deej for peeing on my fire. I was happy untill now. Allthough I was a bit disappointed on how far out the speedo was. it was hitting the limiter of 186 (300kph) but only doing 179mph (286kph).
So I have come accross one of these, http://www.motorbikepartsdirect.co.uk/p ... ctor/4513/ but thought it would be a waste of money as I don't think I will ever be doing those speeds.

Found the original Dynojet graph now ..... and it was 119bhp rather than 124

still they make an interesting comparison ....

The Fuchs one looks more "aggressive" to me ...... and I ws thinking about this - Jamie had to put the gearing into the 'puter, and the unit measured both ignition firing and wheel speed (the reflective tape on the wheel), whereas if I recall correctly the Dynojet unit just measures speed off the drum - and I don't know if the non-stock gearing was accounted for in the first run .....hence if it thinks the bike is on longer gearing it'll show a flatter curve

Oh, and note that by 3500 rpm it's making more than Delvey's does in total ........

Glad to see you all had a great day, and even though i didn't bring my bike thanks for the sausage rolls Jamie and not forgetting the hour long talk about dogs Moose

Oh and the lift home Colin after i snapped my car key

One question i do have and sorry its not bike orientated, i didn't really get a proper answer on the day but FUNKY what was it with that white belt mate

Great seeing some of your ugly faces again

Haha, I knew you were coming and wanted to spank your naughty little bottom with it.
