Third run with arrow headers, open pipe.... Note the Muffler insulation flying out of the pipe.... Most definitely breathing better....

Another update. Noticed another thing..... I find myself not opening the throttle as much. Dont get me wrong here...., but before it took a lot of throttle while riding..... I find myself not moving the throttle as much, but achieving the same ride. Same think happened on my big thumper. I was twisting like mad, during every day riding..... But as the fuel is now correct it simply takes less throttle. And... Fuel mileage you asked..... as of now... It is unchanged. Did I mention this thing is silly at low rpm...... I feel like I am on a stallion...... a very well behaved one, ready to go..... Ha ha.... funny thing... What comes into my mind, is the connect in avatar, between the rider and horse..... ... No exhaust popping anymore either. Simply fantastic. I will ride it a few more days, and if gas mileage remains unchanged..... then the handlebar switch, gets ripped off..... Eddie did mention this, while giggling....

50 mph.... 75-80 mpg.
60 mph.... 65-67 mpg.
70 mph.... 55-57 mpg.
By the computer over distance.... no wind...... I will say that I gained a few miles per gallon..... Time will tell.

Overall riding, I swear the noise is a bit quieter..... Might be wrong here, but it is at the very least a deeper, more pleasant tone. Note the high squeal with the dyno run and stock...... then the next video with my open pipe..... specially at high rpm, the stock was louder.....

And the votes are in...

Ok, here is what I get when I digitized your data and back-calculated the engine RPMs and torque.

NOTE:
1) This assumes that you did not change the stock gearing (no sprocket swaps)
2) That your tire is a Heidenau K60 150/70-17 with similar wear to mine
3) Estimated 5% slip included



##EDIT##

Thanks for the rendering...... I do feel like an idiot though..... as I forgot to tell you that I have an 18 inch on the rear, but with stock gearing......... Sorry.....

18" rear

No problem, the hard part (digitizing) is done and I just have to tweak my spreadsheet.

But first I'll need you to measure the circumference of your tire.
