What would explain the low dyno numbers? My stage 2 103 had True dual Rineharts, SERT, stage 1 air intake and my numbers were 105 ft/lbs torque and 89 hp. My new bike has a stage 4 in it and made 106 ft/lbs torque and 105hp. What could be the difference? Could it be break in mileage? Oil?

Does the gear have any relevance on dyno numbers? Hp/Tq at X rpm is the same in every gear right?

yes what gear it was run in does make a difference. A 6th gear run on a new bagger will show considerable higher number then will a 4th gear run and a 5th gear run will show more then a 4th gear and less then a 6th gear run too. on a 5sp bike same thing 4th will show less then 5th.

That's interesting, I would have thought the higher the gear, the less the number. 1st gear being the greatest torque multiplication and going down from there.
However, it's said doing a dyno run in the gear ratio closest to a 1:1 (5th or 6th if available) is supposedly the most accurate.

Basically I have a SE Stage 4 kit right out of the new catalog. That mean 10.5-1 pistons, 58 mm throttle boday, SE CNC Portal Factory Heads with HP valve springs, 259E cams, high flow injectors. In short this thing should scoot, I would think.
I had a friend tell me that the new build in combination with this kit and cam doesn't neccesarily yield high numbers. The cam is kinda mild.

Wow, after seeing what reserve's numbers are I'm not getting my hopes up too high today when I get my bike dyno'd!
I have 110 octane gas in it, always do in the winter, don't know if that will effect the numbers. I could put more aire in the rear tire!
we'll see!

It's best to have your bike tuned with the fuel tht you will be running in it the most. reserves numbers are pretty on par for his build without head work. I don't get why you would want to "cheat" the numbers with air pressure or whatever other things you conjure up. Unless you just wnat bragging rights.
