  1. Polaris Trail Boss
    I have recently acquired a 1991 Trail Boss 350l 4x4 (w918139). I have had to break the piston free and clean the carb. I was wondering what are all the liquids that i should check before running the engine. Mainly, do i need to lubricate the gear case or no? Thanks, Kevin
