Update on Erica's Ride

Here's an update on Erica's situation.
NRHS provided cylinders and pistons for Erica's bike. I think the compression ratio was reduced from the 10:1 value by using low-profile pistons. She now has 1235 cc displacement.
When looking at the carburator, Lee (Bussy) found a ruptured diaphragm which, he feels, is the "smoking gun" that explains the lean fuel mixture and subsequent detonation damage. Erica and Lee put the bike together over the past week. She installed a new ignition module and plans on dyno-tuning after the break-in.

As of today (4/30/07) she has put over 100mi on the bike without any hint of a problem.
Hopefully this will be the end of the matter.
