Nope, part of the conversion was to install the stock Renesis timing gear.  The problem has been fixed and the Renesis gear is still there.  Just in case you're wondering, the timing gear wasn't installed backwards nor was it clocked incorrectly.

Mark,
 Was the frequency of the teeth going by the wheel too high for the CAS?

Bob,

While good things to check, neither of these were the cause of my problem.  At Tracy's suggestion, I changed the air gap on the CAS to no avail.

Ed,
You are getting closer when you stated that it must be erratic ignition.  (I wish I had someone to give me hints).  Yes, the ignition timing was too far advanced, but retarding the timing didn't correct the problem.  The coils are LS1 units, 6 ea, so any individual coil isn't firing any more often than on a 2-rotor.  So, what's causing the erratic ingition?  That's the question.

  So it sounds like the problem was  indeed ignition - well, its almost always either fuel or spark causing a problem.  So if fuel is more or less ruled out it defaults to ignition.  It probably wouldn't be a rev limiter as they simply cut out above a certain rpm.  So either your ignition timing somehow was off at higher rpm (too much advance?)  or else your ignition was erratic in its firing (such as exceeding the capability of the coils to recharge between firings - unlikely in this case).
 
But, without a shop manual to give me more insight, I must say I'm out of ideas.

Now Rusty!!!  That's too obvious.  ;-)
 
OK, another hint... I got a hint of what might be causing my problem from the ignition section of the Renesis shop manual.

I've got it.  YOU were the problem :-)
