Well, until I posted them I didn't realize how good they were! Honestly, it's stock. Once I hit 1000 miles, I took it in for it's 1k service and did these 2 upgrades to it. That's it.

It's certain the rev limiter has been turned up.

The numbers are out of line with what a well tuned Stage I would be even with a Powervision

What is the normal increase after this on a Sporty? I've got nothing to compare it to.

im suprised they didnt do a before/after chart for you. thats generally more usefull than a 1 time record only run.

If they had, it would likely have also shown higher than normal numbers. The fact that the chart lacks all of the typical dyno setting information, like SAE vs STD, temperature, humidity, correction factor, smoothing, etc, make the resulting numbers very questionable.

It's real easy for a dyno operator to "blow smoke" up an owners *** just to put a smile on their face by giving them artificially high numbers.

Sorry, but there is no way in hell a stage 1 1200 pulled those numbers without the dyno being fudged. 87 ft/lbs of torque just ain't happening on a stage 1 1200.
