So I got a 03 R6 with around 29k miles( a little less because it’s geared down). I had the stock rearsets on the bike and i noticed that whenever I’m hard on the throttle the bike will sometimes “miss” a gear at above 10k rpm. Basically I pull in the clutch, pull the shifter up in which I feel a vibration from the shifter let out the clutch and it’s as if I didn’t do anything. If anyone has experienced a gear lockout in a car it’s the same thing. Now when I got aftermarket rearsets, it doesn’t happen as often but still occasionally. I tried adjusting the shifter lower, adjusting the clutch cable, even changing oil weight. All those improve it but still it misses a gear every once and a while. I’m pretty clueless as to what is the problem or if there even is a problem.
