It's not cutting out and backfiring or anything like that, it's like I am holding the throttle wide open in 2nd or 3rd gear, it is wound tight. I took the left side cover off last night and let it idle while I sat beside it and changed gears, I could hear it change each time I pushed the button. It's weird, I can hear it go into 1st and 2nd but as I going into 3rd, 4th and 5th it is harder to hear each gear change. It's like they get progressively quieter. (If that makes sense)
