hey all, new to the forum but not new to riding or racing moto for what that matters, but im having a problem with my bike. in 5th gear my bike (2010 yz450f) starts to flutter out, almost like the RPMs are still riding but it wasnt catching gear. i ordered a new clutch which isnt here yet, but i ordered it thinking maybe my clutch was slipping since its the bikes stock clutch of two seasons now. after pulling the clutch, it doesnt appear that my clutch is toast. now im wondering if i have a flat 5th gear? has anyone else had a problem like this? Tyler.
