Mike, I haven't had the engine for about a year. I got back from Havazoo, Az last weekend. The Sack O Cats III is back on and at my shop. A new set of pistons, other stuff and a bunch of tweaking on the dyno. There were a few issues that were taken care of, like retarded timing and running pig rich at partial throttle.
I ran it on the lake a grand total of maybe 20 minutes, maybe 5 of those were above 2,000 rpm. One blip to 7,600. It'll take me a lot of seat time to get comfortable driving it again.
