I got some excellent advice on turn 2 and 9 and entry, and spent a while running around chasing some of the instructors. It was good fun. Just before lunch we had a mock 3-lap sprint race. This was totally unfair because my 70hp bike was gridded right next to 180hp 1000cc bikes, but I had advantage of more racing experience.
I got an *EXCELLENT* start, holding a 2-inch high wheelie for almost 200 hundred yards down to turn 1. (A small wheelie is as fast as you can possibly accelerate without pulling a stand-up wheelie and having to roll off the throttle) I was second into turn 1, and 3rd into turn two. 3 more riders got by me on the straights, but I totally held on to the front pack in the corners and finished 6th place right behind the top 5. I could have fought for 4th, but the two guys battling for 4th were getting a little sideways and running off the track and all that, so I decided to just roll in behind them and keep the bike upright. No plastic trophies for this mock race ;-)
I actually went out to the B-riders race as well, but started from dead last so I wouldn't interfere with their race. I passed 10 or so riders on the start, then 10 riders a lap until I was up to 8th place before I rolled off the throttle and let everyone pass me back so that I wouldn't end up taking a place away from anyone.
