Briefly put, the one time I ran at EM was in November '03 and I got in three runs that (two-day) event -- all from the rookie line. I was running as a guest. I wasn't trying for top speed, although I sure would have liked to do so -- but rather just getting some experience driving that fast on a dirt road. My fastest run was a 175 or so, but it might have been faster if wind hadn't stirred up dust and dropped visibility to about 50 during part of the ride. I didn't have handling issues, though -- just seeing issues. I remember thinking, as the dust dropped back down, that I was headed right towards a timing light and that Glen (the timer) would be really cranky with me if I hit the light, so I backed out a bit and turned right and then got back into full pin.
At Bonneville on the ZX14R this past year we were running just about bone stock, with as much as 250 miles on the bike. About the only "performance" modification was to put a data logger on the bike -- but I don't think we ever got around to juggling with the mixture before we called it quits for the week. Top speed was Todd's run of 188+. I made a few runs and they were in the 182-185 range, and Nancy's best was a 187+. During my runs - a good bunch of which were on the long course -- the bike had plenty of room to run -- there just wasn't anything more to get out of the motor. I was running stock gearing and the motor couldn't pull 6th past about 10,700. Knowing that I might get a bit more if I spun it faster I made a run where I stayed in 5th for the first mile and worked on my tuck during the mile -- then hit 6th for the last mile. Fifth was indeed, slower than sixth -- but still not in the rev limiter. There you have it -- bone stock ZX14R, 2008 model, wouldn't go over 188 at Bonneville. Four riders rode the bike -- none of us could get the speed over that.
We'll be back in '09 with a properly-broken in engine. Maybe with the little 250 turbo, too, and even the 12R nitrous bike -- if all goes as hoped-for.
Best of luck with the narco-guys. Be careful.
