  1. Polaris Trail Boss
    Hey so I was given a 1988 Polaris trailboss R/es. I got it running after cleaning the carb. So it was running but not very well. Seemed to have low power, so I thought about a air leak. I changed the crank seals and as I was trying to get the fly wheel off I accidentally touched the stator and...

    Was out this weekend and blew a tire, when it went I slammed a stump on my 96 trail boss 250. Noticed the steering frog on the stem is torqued so my tires face outward and my bars face the right. I was wondering if any other years steering columns would fit my year. Also curious if there’s any...

    Have a 93 350L 2x4 that is having issues starting and running. I had an issue with fuel leaking out of the carb overflow hoses. Determined that the float was stuck so I pulled the carb cleaned the bowl and it fired up and ran for about a day and a half. My son was riding it and then it died on...

    Hello all, I have a 2000 trail boss i rode for a year. it ran very rich (plug black and exhaust smelled of gasoline) once it got warmed up the engine would bogue down or hesitate after 1/2 throttle. It would shut it down on its own eventually and was unable to restart it again. i would wait a...
  9. Polaris Trail Boss
    My 250 2x4 runs great, but will not idle. In the past, once I drove it for a while it would seem to idle. But now, I can ride for 3 hours and when I stop it will shut off. It doesn't even need gas to stay running, as long as I just barely touch the throttle, it will stay running. I am...
  10. Polaris Trail Boss
    I am trying to restore to a good useable condition a 1991 Big Boss 6x6 250. I bought it without a seat, and it seams the seats are nearly impossible to find, even at salvage. Has anyone ran into this issue and tried to retrofit a TB seat onto the frame? I don't have exact measurements, but it...

    As nice as a 2 stroke gasoline trail boss is, It`s not for me, I have been working on diesels for the past 5 years and they have been shown to be superior to gasoline in every way EXCEPT speed. No a 4.7kw diesel will not beat 7000+rpm the Polaris engine puts out, but I would like something with...

    First time 2 stroke owner. Haven't had a quad in 12 years. Purchased this two days ago on a whim after seeing it for sale on the side of the road. It really nice shape. Sorted some carb issues with a good cleaning. Do you have to mix anything with gas? (Didn't think you did, but saw...

    Any recommendations on brand / model of battery for a 1994 Trail Boss? I had a Bike Master battery for about a year and it won't hold a charge, now. In reading the sticky thread about battery maintenance in this section of the forum, it's obvious I wasn't maintaining it properly. I'm not opposed...
