ok so i just bought in 03 cbr 600f4i, it rode great for about a month or so then second gear started skipping if u rode it out, now if i go over like 5 grand it neutral drops. my guess is a shift fork cuz i had the same problem with my dirt bike, im thinking about just doin myself but im not exactly sure what im getting into doing it on a street bike. if anyone has pics or tips or anything that can help that wil be great, thanks guys
