I see this guys numbers, on his dyno, I also saw a 4th Gear Roll, or pull, I talked to real motorcycle gearheads, they tell me dyno numbers can be deceiving because they do a 5th gear Roll or pull rather than the 4th gear as outlined in the above dyno.
The gearheads stated this could be bragging rights from the bike owner, or deception of the dyno guy giving false numbers to the bike owner, leaving out the 4th Gear Roll.
I would like to see more software packages list the 4th gear Roll, to keep things on the up and up.
Reminds me of the butcher putting his thumb on the scale when weighing the meat!

Lots of shops will do one gear down because of the fact a WOT pull at 5k will have that rear tire flying, bad tires are dangerous on a dyno.
Top gear pulls give the truest results.

On a Dynojet Dyno, the industry standard, could be higher or lower. Numbers do NOT matter so much, anyways, I just wanted to point this out to you.
I love that bike and with all the proper stuff to make those TW6s work... I bet it is a Hoot to ride!

True numbers are only reported by a dyno if the bike is in 1:1 gear ratio. On a 5sp, this is 5th, on a 6sp, this is 6th.

My .drf file indicates a speed of 132 mph at a shut down of 5,800 rpm. I am not sure if that is calculated from drum speed or directly from the ECM/SEPST. Maybe someone with more DynoJet knowledge could chime in here. It would make the most sense that it was from the ECM/SEPST since actual speed with my tire size (200/50/17) and sprocket (30-T) is 105 mph at 5,888 rpm in 6th gear. The indicated 132 mph would be about right for an erroneous speedometer read with my tire size, sprocket and speedometer error.

2013 Road King Classic
Stock 103 (no head work, stock pistons, and stock valve springs)
Screaming Eagle Super Tuner
D&D Fat Cat wrapped perforated baffle
SE Extreme Billet A/C
Andrews 55HG Gear Drive Cams
31 tooth front sprocket
On the dyno it made 100.8 HP, and 109.1 TQ
:
I love the idle!
This thing rips, hauls *** from 2000 to 6200 RPM ( that's where I shift if on it hard, but it never stops pulling hard) it's ready to go right when you take off and never stops pulling all the way to redline, it really pulls on your arms. This thing is a hoot to ride; it will break the tire loose in first and second if you hit it too hard. I'm having a blast!

Wow. I'm curious now about what mine would do. If anyone knows of a good Dyne here on the island of Oahu please let me know.
