Dyno Day.

Thanks Cutty. What is the secret? I figured copying the code from there would work.

130 hp at the rear wheel is very nice. Couldn't he take a tack reading off a spark plug wire?

Just to refresh everyone about engines: Engines make torque, not horsepower. The dyno measures torque and uses a formula to convert the torque to horsepower. Torque x engine speed/5,252 = HP. Therefore, torque and horsepower at 5,252 rpm are always equal. And an engine is most efficient near it's torque peak.

Yup. Have to tear off the whole airbox assembly to get at the front one.
Didn't realize (until tonight) how easy it is to get at the rear... just remove the seat.

Provided there is no rain, I'll run it tomorrow night.

so then how did they caculate the hp with out knowing the torque?!

D&D sucks. And the Saron looks like butt. Someone (DRUMMER!) needs to get one worked up that stays under the bike where it belongs.

The saron is under the bike, but could be better looking.

I'm waiting for drummer or special ops to get something done.

The dyno measures torque. You mean: How did they calculate hp without knowing the rpm? According to the formula, they have to know the engine's rpm in order to calculate the hp.
