Well done Dude!

Awesome Lawson the second! (again)

Wouldn't have happened without knowing you where up my arse so to speak.

So in effect it's your fault I won.

Smellory could be a whole different ball game.

Eh, well done lad!

Only one big slide which Kev Palmer will tell you all about.

Kev told me that only happened because you were trying to keep up with me through Clearways!

By the way, my tyre was looking a little like yours by the end of the second race... but my 58.2s lap came on lap 14 of the second race, so they seem to grip no matter how bad they look.

what was my fastest time last year Ron, on the worst tyres ever to grace a DD bike

I would put it up here, but I havn't got time to look right now mate.

I think my fastest lap was near the end, I took it easy for the last couple of laps but just before that was my fastest lap

There are two types of Dynometer, I am not up on how they work, but to say that the SAE dyno reads Lower than a DIN Dyno.


Horsepower is a measurement of the engine's ability to perform work. One SAE
horse is the ability to lift 33,000 lbs one foot in one minute. One DIN
horse is the ability to lift 450000 kg one cm in one minute. For the same
power the SAE measurement is thus 98.629% of the metric DIN measurement.

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
