I recently came across the problem that when I pull the clutch and put the bike in 1st gear, it will stall. You cannot puch the bike while in gear with the clutch in either, so the clutch isn't engaging. the bike is a 99 rm 125 and I rode it about a week ago but it has been sitting since, and it never had this issue during that ride. I was wondering what the problem might be. The cable tension in the clutch has never been adjusted so would it be something as simple as that?
