Up to 200 miles on the bike and every time I smile more with it.  It’s a blast to ride.  One shift rod bolt got loose and one switch came loose and that’s it for shaking her down.

Made it to the dyno to see how’s she is tuned.  I knew she was a little rich.  Baseline it had a hell of a dip when the cam was coming on.  We dropped the needles two positions and removed the baffle from the pipe and that smoothed it right out.  Next we went from 92 mains down to 90’s and it was amazing.  We gained right about 4 horse with those changes. 

We started off right about 35 hp and ended at 39.2 hp and 23.3 ft lbs with a great curve on the power.  We were cutting it off at 9500.  I’ll see if i can figure out how to load the video

"Of all tyrannies, a tyranny sincerely exercised for the good of it's victim may be the most oppressive. It may be better to live under robber barons than under omnipotent moral busybodies. The robber baron's cruelty may sometimes sleep, his cupidity may at some point be satiated, but those who torment us for our own good will torment us without end for they do so with the approval of their own conscience." - C.S. Lewis
