Dyno Tuned

[Mother Goose]

Finally went and got my bike tuned on Friday afternoon. Took it down to Fay Myers since Clarkie was working out of their shop. He's moving to Vegas this week, so I had to get in before he left. I wouldn't give my bike to anyone else. Here's the results....



All numbers are at the wheel.
Started off @ 152.30hp / 71.81ft lbs.
After the tune 159.13hp / 77.03ft lbs. (almost 90 degrees for this run)

I'm really happy with how it came out. Figured I'd be around 160, but was really looking for a smoother power delivery, and I got it. The dip from the ex-up valve isn't quite as bad as stock, but the power and the throttle are smoooooth. I've only been able to ride twice since the tune, and both were in traffic, so I need to get some open areas and see how it feels to open it up now.

Cool, enjoy it!

A quick note on Clarkie: While he is going to Vegas for the winter he is coming back to Fay Myers next spring. Just have to wait a little to get your super dyno tune if you havn't already.

Nice.... That's a lot of power at this altitude.

It definitely moves when I ask it to.

The dynojet dyno will correct the horsepower based on air temperature, barometric pressure and humidity so that the results are the same regardless of location. The reality is there is about a 15-20% power loss at the elevation.

Cool - I didn't know they did that. Still, that is a lot of power for a street bike.

Couple good articles by a local guy-

So do you think I would be putting down roughly 183 at sea level (using 15% loss)? Seems like a lot! Then about 12% for drivetrain loss, I'd be looking at 205ish @ the crank.

I was checking different sites for calculations to factor in altitude, found one and it said the correction should be 1.602 for the temp/barometric/humidity for my last run. What was used was a factor of 1.24. Wonder if there's a calculation to use those 2 numbers and figure out what it would be @ sea level to get a more accurate number?

Lol no it's the other way around. You're probably putting down around 159 at sea level and 135 here.

Enough to make a dude move to sea level.....almost.

I tell you, I bought my '01 new in Cleveland, and MAN, that thing down there made scary power. I'm 215lb and at anything over 5k rpm down there, if I whacked the throttle open (no clutch needed) in 1st or 2nd, the front end shot straight up, almost hitting me in the helmet it came up so fast. It's a HUGE difference.
