Right. *rolls up sleeves*.... where do you want me to start????
I will happily pay for
ANY 620 to be dyno'd with
ANY 675 carbed bike on the same dyno, but you'll have to promise to re-imburse me if there isn't at least 7bhp difference. That's a modest 13% difference.
To give you an idea that has the equivalent effect on power/weight as removing 22kg from the bike!

the expected power outputs of a sorted big bore 583, standard 620 and big bore 620 are all around 62 -65 bhp

********. Try 51.5, 59 and 62.

however all this about different dyno figures is also very misleading as each dyno has a different reading to the other ...
|
but three different dynos delivered bhp figures within 0.5 bhp for three 675 bikes? "Very misleading"????

for what it is worth i believe changing the rules so quickly as a knee jerk reaction would be wrong ... it's just too soon ...

Couldn't disagree more. Sort it out now or you'll have an entire field of 675ie checkbook racers.

No we don't.

Andrew produced the ride of the weekend as far as I was concerned. I hardly think this thread has anything to do with rider ability. I'm sure CK & AK are biting their tongues on the whole BB issue. Where would Andrew have ranked with a 680ie???
I had an enormous amount of fun on the weekend, I have huge appreciation for the race committee, but that needs to be reciprocated back to those that have invested a huge portion of their savings/loans/time on getting on to the grid.
