Oh man, why would this happen?

alright, i we were all out riding... and i let my buddy take my shee for a rip... he said he couldnt get it into 4th.... i take it out the road, everything seemed just fine... went through all the gears... then when we were screaming down a back road, i couldnt upshift anymore and i could only go down one gear.... i think it was 4th and 5th... i limped it back home and ripped my side cover off.. i found the part of the shift dealy that grabs the studs on the shift star... you know which part i mean... i found it kinda wedged in sideways instead of up and down... idk how that happened? anyone have any idea as to how it coould happen? hard shift? needless to say, after looking around for oil/antifreeze/adjusting my clutch, we finally get to go ride... yep, you guessed it. rolled this bitch right over top of me... down a highwall. all it did was bend the lip on a wheel and turned my bars down, but i just loosened the bolts and slid it back up... what a day. fun though..

Those do wear out after about a million shifts. The part that grabs the pegs on the shift star gets play in it and makes it harder to shift and can even cause extreme conditions as in your case, not shifting at all. The whole shift shaft assembly is like $35 from any oem parts dealer.

instead of a stock one you could get a modded shift shaft from jeff at fast racing. they're supposed to shift smoother, you'd have to ask him.
