That "bent shifter fork" could easily turn in to a tranny repair costing $300-$800 if you do it your self.......
If the bike is in great condition otherwise might still be an OK deal if you can get it for $1500....Lot's of unknowns with the tranny until it comes apart for repair tho"
Some sucker is going to think he can readjust the shifter on its splines & "fix" that problem! Leave him your best offer & your cell #. Maybe if he gets tired of dealing with no-$ losers, he will call.
