No sweat. I hope you get it figured out soon. Intermittent problems are the worst!

If the engine increases in speed (revs up), but the bike doesn't, there's something slipping between the engine and transmission. The only thing that can do that is the clutch. That's where I would start.
After Reaper's engine build was complete, if I got on the throttle hard, the clutch would slip due to the stock spring not being strong enough to hold the power. Upgraded to a heavy duty SE spring, and the problem was solved. In your friend's case, it could be that (I believe the pre-Twin Cams had a set of coil springs rather than the single diaphragm spring my bike has), the friction/steel clutch plates are worn out and need replacing, or it could just be really out of adjustment.
Cheers!
