I have a 2006 YZ250F, and whenever I go to shift gears while riding sometimes I really have to kick it hard. Sometimes even twice cause the first one didn't do it. I fiddled with my clutch lever cable a bit but not much of a difference. Sometimes when it's cold if I hold the clutch all the way in, and put it in gear, it immediately stalls. Is my clutch lever still just out of rig or do I have a bigger problem with the actual clutch disk?
