It's a little confusing to look at the results because of the chronology of events. Last things first, I finally put the record at 144.360. Here's how it went:
- 1st run (first time I ever rode the bike, to tell the truth) was 136.699. I discovered I didn't have high enough gearing...the bike went right straight to 10,000 RPM in 5th gear (about 147) and then did a series of snaps to the right, followed by big weaves. After I slowed down below 140 it was ok, and my measured mile was the speed shown.
- 2nd run (after deciding to realign the rear tire) this was my Monday morning return run in a little wind from the right. I ran through at a little under 10,000 RPM, using about 3/4 throttle, and went 145.384 with no handling problems. On this run I ran down the left edge of the course. I now had the record at 140.855, which was not acceptable.
- 3rd run (another qualifying run, but against my own new record) Believing the bike was ok and the left side of the couse was good, I tried to run a 10,000+ RPM pass. This time I was in trouble before I got to the 1 mile mark and nearly hit the sign. I tried to keep my speed through the weaves, but only ran 140.875. That was enough to allow another return run the next morning.
- 4th run (after deciding I must have had wind gusts on the 3rd run) I had a strong enough wind from the right, that the banners were fluttering at the start line. The bike hit the 2-mile line at over 146 and I went full throttle to see what would happen. It pulled cleanly to over 10,500 and was about 1/8th mile from the 3 mile (end of the measured mile) when it pitched right and began weaving again. I kept the throttle open, trying to preserve what I could, and got a 147.846 mile. This made the new record and I was done.
After the fact, I noticed that the front fender has rubber marks inside the left side, and the fender is not symmetrical (angled right on the forward edge). I'm confident the fender blows sideways at around 150 and kicks the front tire out of line. After that, it doesn't recover until below 140. Next time I'll just skips the front fender.
I'll make a shorter post to tell about the 500cc bike, with pics.
