Hey guys,

So I've been surfing/absorbing this forum from the shadows for about a year now, not sure why I never registered before but I'm here now!

Here's my winged stallion:

I picked up this beautiful machine in September of last year. The previous owner was a motorcycle tech and good friend of mine. Definitely one of the cleanest and strongest running air-cooled Buells I've ever come across, which is exactly why I just had to have it. The bike made 98.2 RWHP and 84.1 ft-lbs with the current setup on a Dynojet 250 SAE corrected.

Everyone take a moment to congratulate yourselves on having impeccable taste in motorcycles :up:
Cheers

Thank you kind Sirs. I was typing a response with more detail related to the hp figures but realized it got wayy too long winded so I'm going to post it in the dyno thread.. dang mechanical enthusiasm got me again.
 
Alright... I know I've seen a dyno results thread before but I've searched everything I can think of and found nothing. Is there one or was that another site?
 
I guess I'll just leave it here for now.. I've seen quite a few people on here discouraged because of low dyno numbers. Well cheer up fellas! Your disappointment is likely sourced from improper corrective variables on the dyno end rather than from performance of your machine. These bikes made just over 100hp at the crank when they rolled off the factory floor. If you have intake, exhaust, and improved ecm tuning of any kind, you should be sitting right around 110(average) - 115hp(exceptional) at the crank. Now, we all know a dyno measures WHP, but a lot of things can go wrong in that conversion. For example, the standard SAE correction value for mechanical efficiency is 85%. That number is pretty good for most cars that are turning heavy flywheels and putting power through large drive shafts and differentials. On a motorcycle, mechanical efficiency is actually somewhere around 90% or even above, due to more direct power delivery and smaller rotating parts. Your dyno operator can custom input these values to give a more accurate readout of what your machine is actually capable of. Consider this and many other factors that might be robbing power from your stationary bike and an improperly corrected dyno could have around a 12% error. 87RWHP x 1.12 = 97.44RWHP = 107.2 at the crank. Feel better?
