As Bradders said, his reading was 46bhp in SAE and when converted to DIN bhp it was 49bhp, and as maths is not my best subject i will leave it to you to work out the DIN bhp from your 53 & 55bhp, if that is they where not converted to DIN.

Well I would ignore that figure as its not the same power measurement
Based on the figure of 98.629% you would need a SAE of 48.33 bhp to arrive at a DIN figure of 49 bhp
I will hopefully be provided with all the figures so I can see what if any ammendments need to be made to our rule book
From what i can work out the Parkitt Dyno reads in NET SAE J1349 spec which then needs converting to GROSS DIN 6270 spec
This conversion seems to be roughly 7.5% so multiply the figure the Dyno reads in by 1.075
My bike read around 55.6 BHP (SAE) add 7.5% to this and you get 59.77 bhp (DIN) the DIN Dyno I had it on last Tuesday measured it as 61.1bhp
My Class B Monster measured 45.52 SAE which converts to 48.93 DIN
