I had my latest gen1 (full monty fitted) dyno checked at rencullen at Mallory Park last year . I paid full price, the bike had several runs, the operator has to get used to the bike as much as anything. Even in the same session the bhp figures varied just by operator effect alone.As such I reckon this run is too small a sample to make solid recomendations.For the record, my best run was 137 max, thats with a race can with a db insert, so probably 139 would be achievable without it. However the tuner said my air fuel ratio was the best hes seen, and he would not be able to better it.Even more impressive was the flat torque curve, which is just how the bike feels on the road..with hard acceleration starting as low as 4k rpm in top , it does pull really hard. Just the power delivery characteristics I want , peak bhp aint so relevant for me.
My opinion is -
check air filter is not stock, that will skew all the figures, it should be bmc type
get the run done with a race can
make sure engine is serviced, carbs balance detc, so it is at optimum
pay for a full run, usually at least 15 to 20 mins, and get full analysis of the results.
as a comparison, my first gen1 as stock was 127 bhp, after dynojet stage 1 kit fitted was 133bhp peak. But the full monty is an improvement on this, especially in the mid range.
