steve,
before you get to crazy with that dyno sheet, beaware that its the old bike and his mechanic had totally messed up the valve adjustment,(by as much as 6mm on one set of intakes), and the throttle bodies were way off,(one side of had the brass screw at a half turn and the other at 4 full turns). Plus he didn't check the battery and it died 12 hours later.
I was not happy

TonyJJ,
I agree that building a motor that doesn't last but a few miles is not worth it for the street.
But I feel a motor can be built with in the limits of the engine design to fit my posible needs. For example if different valves are placed don't go to big, be conservitave on the porting, don't over bore the cylindars and run to thin a sleeve.
Stuff like that.
This is looking very interesting.
