This little escapade today with my broken throttle arm turned out causing a lot more damage than I originally thought! About 3 gears were ground off the spur gear. The melted plastic from the spur gear solidified all over the clutch bell gear. My MIP 4N1 clutch melted and ruined the clutch bell and clutch bearing. Ain't it funny how one little broken part can cause all this collateral damage. Well, I guess it ain't that funny, this one's goona cost a bit of moola.
