1985 Polaris Trail Boss Go Kart Project

Recommended Posts

hey guys my name is preston and i just joinned the fourm and so far i am glad i did so. that aside me and my frien jus aquired a 1985 polaris trail boss with a blown motor for $50 and we have a crazy plan for it.

we wanna take the existing frame ans strip it down to a rolling frame and then turn it into a go kart. Now the reason that we wish to do so is because we think its a moderatly easy way to build a Kart with both front and rear suspension.

i am wondering if anybody has tried this with similar quads or any input in general would be great.

i think it would be freaky cool ... its going to be a heavy "go-cart". are you keeping the wheels the same on it? what are you going to do for a motor? i would like to see the pics you post ... :yes:

Not sure how heavy it's gonna be... the plan is to shave as much unnecessary metal off as possible. For the wheels and tires im thinking keeping it stock and using a modified version of the CVT transmission. As far as the motor goes we are going to start small, like a 5hp Briggs as a starting spot to get the suspension and drive line fine tuned. Then we are probably going to drop in the biggest motor we can find or it will safely Handel.

Later today I will be posting pictures of the quad. Unfortunately we have determined that the 2 stroke 250cc engine that came with the trail boss is not salvageable. So no th only motor w have is a 5hp Briggs motor that we will half to run until we acquire a bite bike or atv motor.

As far as the build is concerned we have decided to remove the transmission and mount the motor there with a centrifugal clutch to start off just to get it moving. We plan on cutting the frame in half and extending it about 3 1/2 to 4 feet in length to add space for a seat and leg room. We are going to cut out the back bone of the frame so we have room for our heads and w will add supports running parallel to the bottom tubes of the frame. I realize the May be hard to visualize but I will post picture along with my best friend who will hopefully be joining the forums soon.

so I have finally decided to cut the quads frame. I just need to decide on a tube diameter and thickness to weld to the existing ATV frame.

      I have a 2000 Polaris Sportsman 500. A year or so ago we got it running after replacing the kill switch. It ran great but after some use for a couple months it got a flat tire and for some reason we just forgot about it and it sat for some time. Before it sat i replaced the gas cap, fuel filter, fuel pump, petcock, battery, starter relay, oil and oil filter. I recently went to start it and it started so quickly and without choke or throttle but the ATV wouldn't move till about 1/4 throttle and it wasn't really a smooth ride until 1/2 throttle. it also would bog out randomly after you came to a stop and sounded like it was getting too much fuel. I cleaned the carb and adjusted the air/fuel screw to 1 3/4 turns out.  I also messed with the idle and the throttle cable adjuster up on the handlebars. It's safe to say it now runs worse than when i started working on it 2 days ago. It takes more effort to get started and bogs out idling after about 30 seconds. I tried adjusting the idle but every time i do it'll get to a sweet spot but after driving it down the driveway and back the idle will go up and down to the point where i can't put it in gear because the gears will grind. Any thoughts or ideas would be greatly appreciated. Thanks

      So few months ago I acquired a 01 Explorer 4x4 (think its a 350 but not sure) 
      Anyway the owner said it started reving very high, shut the key off and still kept running 
      until finally he shut off fuel and it finally died. During the run away he said the exhaust got 
      red hot and has melted plastics to prove it. Said some thing flew out the tail pipe, I kinda figured
      it was the top of the piston. Anyway finally got around to looking at it (have a lot of other projects in the works)
      and checked the compression, Shows about 40 psi. Can hear air coming out the carb while rotating the motor over. 
      Gonna pull it apart eventually, don't hear any noises or binding in the stroke, You think the piston came apart? 
      any horror stories of these and is it worth my effort and money? Don't really have any money in it yet. Thoughts? Az

      Trying to figure motor size, says nothing on plastics, or the title, only numbers are EC25PFX 01 Which
      are on the cylinder. The vin code is 4XAAG25C312459874
      Tried vin search but still doesn't show motor size.

      Hi All,
      Want to show you one automotive show that I filmed in my town called Crazy Race. This was two day race in Qualifications round, Semifinals and Final. In this 4 parts I am showing best moments from all rounds and entertainment of the show.
      Crazy Race Part 2 contains a qualifying round where all riders race against each other, selected by lot and split by two. They are free to drive in any direction and to hit their opponent's car everywhere except at the driver's door. Anyone who intentionally hit the other car in the driver's door is disqualified. Winner of each race continue in the semifinal round. In this part I will present the best moments of the qualifying round! 
       
      Part 3 shows you the best moments from Day 2 - Semifinals and Final. Battles in the semifinals are among the winners of the first day races, but this time they are selected by lot and divided into 4 battles of 4-5 cars each. The rules in each battle are that they only have to drive in one direction and try to neutralize other opponents until there are only two players left. Then the battle between the two last drivers has the rule to drive in any direction until only one who has qualified for the final round is left. Again, anyone who intentionally hit the other car in the driver's door is disqualified.
      For the final round there were only two cars left, because the other two players who got the right to be there had problems with their car and could not participate.
       
      Part 4 containing entertainments between battles and winners rewarding.
      This event will have second round in 05-06 October 2019 and also will be filmed  For this new round I will filmed in many new angels and places. Will prepare a lot more videos and many new entertainments . This 4 videos was my first try so many things to wish for better filming in the future one.
      Hope you will like them and of course feel free to comment and to ask everything. Hope you will Subscribe to my channel and to be first to see my other content and of course new round of Crazy Race! Thanks!

      Looking for a download of a manual
    • By warkcol
      I am having an issue where it sounds like the gears are slipping if I hit the throttle really hard and also after letting off when the engine brake is applied. Also, the drive train that goes to the front also rides again the gear shift box. I will attach pictures and a video here shortly.
      Thanks in advance!

      Trying to change front wheel bearings. I removed the cotter pin and castle nut. Hub won't budge. Is there an additional retaining clip? Seems to be one of those push on type that barbs on the thread of the spindle. How do I remove it?
