After the D200 this really got my wheels turning. You have the top guys doing 180 MPH on SS legal R6's. My bike is no slouch, but the best I've ever seen on the GPS is 167. Top speed is free lap time at Daytona, and there's alot of it so tweaking things to get it right can pay big dividends. I recall @stangmx13 chiming in on another thread about shift points, and that got me thinking that maybe I need to put some more effort into getting this right. Yes, I'm bigger, 5'11" 190. Yes, they are getting a better drive. But with over a mile of track we are at terminal velocity. When I did the 200 in 2016 on my older R6, it was making 123 on MR-12 and I couldn't get more than 158 MPH. I was pretty new to the 4 cylinder thing and I think I was shifting at around 12-13K RPM. With this "short shift", the bike would fall into a range where it would not pull out of (below the torque peak?), thus I think my top speed and acceleration was hurt. Compounding that, the motor was very tired and although it made good peak HP, the midrange was weak. Fast forward to October- New engine build, same peak HP, but better midrange. I was winding it to death, sometimes not even using 6th if there was a headwind. She hangs around 15 or 15.5K RPM in 5th, so I assume I was geared correctly. Last weekend, I focused on tucking in tight, running the high line up by the wall, and winding it past 15K before shifting. Then I got the camera with the GPS speedometer and watched the footage. That showed something strange, past about 14.5 or 15K (can't see the tach in the video) the bike stops accelerating. Upshift and the acceleration starts again. So maybe my gearing is too short? Not sure how accurate the GPS in the camera is timewise. But it was within a MPH or so of the AIM SOLO for top speed. I spoke with @MELK-MAN on Saturday, and among other advice he's using taller gearing. We didn't discuss the top speed issue, just some infield stuff. I understand why he's using that gearing for the infield, but Greg, are you pulling 6th on the banking? I'm running 16/43 gearing and Dunlop 180 rear slick.
