I've had several dyno runs and posted all the information here after each time. I will summerize:
790cc with Mikuni HSR42 carbs and modified stock pipes = hp ~62 Torque 49 (constantly breakin up, way too rich even with smallest jets and no accellerator pumps)
Same setup but added Thunderbike pipes, hp~65 Torque 50-51 still broke up badly though causing decrease in max torque and hp
Stock carbs, 790cc, freak, 160 mains, stock needles = hp 65.4, torque 51-53 ran excellent, gas/air nice and level around 13 in all rpm's.
No dyno yet after the big bore, coming one of these days.

A word to the wise is not necessary. It is the stupid ones who need the advice. Pat
