So there's a stretch of road here in CO called blue mesa reservoir which is long and traffic less and today I had my bike with it wide open in 6th gear and gaining speed, Here's the thing though, I know I didn't get out of my powerband but my bike started losing power untill I dropped rpms. It was like I'd gotten out of my powerband early 3000 rpms early and needed an extra gear Any ideas? I road it 60 more miles that day and the bike was fine. Overheating? Needs a tune up?
