ive got the haynes manual wiring diagrams. just folow your wiring back and check your fuses. is your steering column switches working fine??
as for the fork, there is no bushings, just a ball the fork goes on, and gets grease. the slave just pushes a divot in the fork.
i cant find any pictures of the fork best one...
