Can you grease the pivot bolt on a Fxstc because when I bounce up and down on the seat something is squeeking and I think it is that long bolt that goes straight throuth?

 

Not with out taking it apart. It's probably the rubber pads under the seat. Pull the seat and wipe them off and put a touch of silicon rubber spray on them. If it stops you will know what it is. It will probably come back shortly however. My seat is not stock but I fitted the bushing so they all touched equally. Two of them needed shimmed by 1/4" Also could be the belt drive on the front pulley tighten up slightly. Get someone else to bounce while you listen . Sometime it take a stethoscope to pin point it.

 

Shock bushings?
