Was back at NHMS again. Track was beautiful for 2 1/2 days and then right at the beginning of the time trial it starts raining hard. By the time I got out there it had stopped raining and a sort of dry line was forming. Was still pretty sketchy in places, and I had no wet practice sessions to relate to. Also attempted to blow the engine up by shifting from 3rd to 2nd at redline. Engine momentarily revved to about 9000 rpm and I caught it quickly before fully letting the clutch out. Ended up with 1st in the SPB class with a 1:22.2.
