910 Guess the stock dyno

I just got the results for the dyno runs for my new 910. I had a base run done on the stock bike and then after the MV-SP headers and PCIII w/a custom map.

Guess what the stock 910 dyno'd @ ?
Come on, don't be shy.

Depend on the dyno but a DynoJet dyno would most likely see about 120hp stock and hopefully 128hp with the mods. (rear wheel)

This is using the SAE correction factor and about 12% driveline loss.

4th gear pulls also,(industry norm) 5th gear will give inflated numbers.

This is real world wheel horsepower, not some "happy" dyno numbers.

STD, uncorrected or DIN numbers will be higher.

What do I win?

John, is 12% driveline loss a nominal figure for most bikes?

Chain drive bikes average about 11-14 percent. Many conditions contribute and it is hard to put an exact figure on it.

Chain condition and tightness, tire pressure and size/weight, rear brake drag, bearing condition and even the oil used will change the numbers.

Shaft drives are usually in the 16-20% driveline loss.

No prizes.... 'cause Cynthia didn't guess. She would have won a bike date.

Nidan was closest. Stock= 113. Yes, that surprised me too.
After= 125.

I just put my f41000 on a dynojet dyno on tues night with rg3 and mid pipe and chip. It put out 130hp running no correction just straight rear wheel hp.
A ZX10r was running 127hp in comparison
