Got her dyno'd yesterday, sheet attached.
I went out to Sunnybrook bike stop yesterday cause they had the mobile dyno set up, got the bike dyno'd and came out with 76.33 HP & 77.85 Torque.
He said everything was down a bit as you can see on the dyno sheet the temp was 33c or about 92f but I was pretty happy with the numbers and he agreed that without cams & headwork that was a "real strong sportster".
He did say I would benefit from bumping up the red line to 6500 RPM.

Your loosing power in the mid range, way too rich. Your top end is lean also causing lose of power. There is more there if the fuel ratio and timing are corrected. You have the potential to get at least 80/80 out of your bike. With fuel changes you would also be able to take advantage of a higher red line. Your bike is strong but there is more there.

Yes he did say that with a full tune he could smooth out the air fuel and bump the redline with the PCV and probably pick up 2 to 3 HP, plus he figured at least one HP if it was a cooler day, that would put it right around the 80 mark.

That's a good idea, I loaded the program into the laptop when I got it but never messed with it because it ran so well and I didn't want to mess it up but I think I'll try that and see, I doubt it will make a noticable difference but I noticed a lot of guys there had gotten this guy to dyno theirs last year and he can print the graph with last years run and this years run so I will get it done agian in September when thay are out there again.

Make sure you save a copy of the existing map on your hard drive before making adjustments. I'd start small, +1 or +2 to add fuel (up top) and -1 or -2 to remove fuel(around 3500). I'd do it for the 90-100% throttle cells.
I agree that you may not notice a big difference but you've got the a/f print out so might as well take advantage of it. Post up if you don't feel comfortable doing it or don't fully understand what you're doing. There are many here running the Power Commanders that can help you out.
