Yeah it was running really well for me as well. The copper gasket and 93 octane fuel made a huge difference after i added the ngk iridium plug. That little thing is a powerhouse! Kind of makes me wish they made street legal 2 stroke sportbikes! imagine 250cc's with that kind of tuning and performance!
make sure you keep the cylinder head screws tight, we spent a couple hour one night a few weeks ago trying to figure out the carb isue we were having which turned out to be an air leak at the cylinder gasket. but youre a pro so you probably already knew that. =)
Let me know if you need a test pilot. ; )
