The moment of truth....

Today was dyno-run day.

Here are the results.
Almost 52 pound-feet, at 3500 RPM with 22 degrees total ignition advance (via restricted advance weight movement) and the cylinder head temp simply would not rise past 275 degrees Farenheit on the dyno.  This is with small valves, small carbs, stock everything except the combustion chamber mods.  The bike feels very similar to my K100RS 2V in the way it responds to throttle and is completely ping-free.  Oh yeah, everything between the head gaskets has 117,000 miles on it.

I think that the combustion chamber modification has been a successful experiment.  I will post fuel economy numbers once I get tired of playing and actually ride it responsibly.
