i finally got around to dyno'ing my bike... whats done is basic stuff, it was jetted at the dealer for the SE AC and mufflers, so i don't know what jets it has... i have the baffles removed and just put on a Ness BS AC... i have no way to post the chart but i'll give a run down... it has 2 torque peaks, a small dip and needs a little fine tuning, but runs great otherwise, the dyno tech says it could be anything from bad gas to the ignition module (which is the SE unit)...

TQ peak at 3000rpm: 74 lb-ft
small dip at 4000rpm: 69 lb-ft
TQ peak at 5000rpm: 75 lb-ft
HP peak at 5900rpm: 79 hp
HP from 5500-6500: 75 hp
TQ from 2500-6000: 68 lb-ft

an 80 75 motor...beautiful...That used to cost a few bucks to get there. Go enjoy.
My 02 1200 had about 65hp and to get to what you have I had to get the heads ported.

His bike is 70 lbs heavier than yours. They would have probably been pretty
evenly matched on the street. Everybody turns green when the rubber
Guys dyno their XB motors and get those "Big for Stage One" numbers.
The MoCo parsed out the power to compensate for the extra weight.
I rode my buddy Kenny's stage one '03 1200C and trounced my other 2
friends, an '04 1200R and an '04 1200C. Not even close.
