Re: Reasons for a low dyno reading
Seems like I was slightly mistaken with the dyno results (more like I was given mis-information). On the face of it now the bike doesn’t seem weak as I feared.
Comparing the results below the against my K8 for me shows that the bike is 13hp up on 2 fit & healthy current model stock CBR1000’s & a piped 2005 ZX10R. Seeing as the Akrapovic website dyno has both bikes reading within 3hp of each other stock that’s a good sign. More tellingly it’s 3ft/lb stronger in the midrange than the other literbikes which is a bigger indicator of how fit the motor is & a good indication of compression, parts wear etc. Am positive now with less oil in the sump, a well sealed exhaust, clean injectors, the bike strapped down to the dyno rig & the correct AFR tuned to the bike I would see another 5 or more ponies liberated which would put it into modern litrebike power – happy days
May get a dyno chart readout also – stay tuned. When I get the bike converted back fully to road spec I might take a trip to PTR for another dyno run.

From the above chart it shows that higher mileage bikes still make good power as long as they’re taken car of. Also BMW seem to underquote their power figures - just like their cars....
