It's not that simple is it tho ?
A bike with 100 hp loses 15hp thro the transmission yet the same bike tuned with 140hp loses 21hp even tho the transmission is exactly the same ?
All you can get is educated guesses at crank horsepower. I don't know how the dyno shops that give sheets out with crank horsepower work it out when the reading is taken from the wheel ?
In fact I see no reason why they would estimate a crank reading other than trying to impress the owner with bigger figures.
Also comparing readings from different dyno's on different days is no good. All that actually matters is before and after on your own bike.
My TLR race bike had 139 at the rear wheel on one dyno and 134 on another with no changes to the bike.
