I discovered that my bike (99 rm 125) stalls when i put it into 1st gear. Its strange because it never did this when i brought it home. I changed the oil and tried. Same thing. Tried adjusting the clutch cables but it would still stall. I can get the bike not to stall if i put it in gear while rolling down my driveway, but it is cause for concern because when i shift gears it is probably hard on the clutches if they truly are frozen. I've only ridden in once since this problem. Any help would be great.
