I got the tiny and very light weight new battery installed and she fired right up. http://www.batterystuff.com/powerspo...09A2-BS12.html
Amazing technology with those lithium batteries.

Took her out for a "high" speed run. At 75 MPH indicated (probably about 68 MPH real) she is turning (with my 38 tooth rear sprocket) about 7600 RPM in fifth.
Vibration is getting very uncomfortable at that RPM.
