Stuttering between 130-140mph
I have a 2009 Yamaha R6s and i been having this same problem for about a year now and can’t seem to figure it out. When I’m riding sometimes it feel like my acceleration is not as quick and it should be and when i get to 130 in 5th gear it stops accelerating and starts stuttering at about 10,000-11 RPMs then i switch to 6th gear and it goes to about 140mph and does the same thing again it only stutters when my throttle is at 100% when i let go to about 95% it stops but still doesn’t accelerate. I’ve change the clutch, coils, spark plugs, and fuel pump and still having the same issue. Any idea of what it might be or has anyone came across this same issue?
