I've read a couple people saying they found em out of spec from the factory. Just got my UTV recently and it's on my list here in the next couple weeks.

 

As far as tools should be easy: Allen wrench to pull the covers, 10mm box wrench for the lock nuts, a wrench for the adjuster, and a flat feeler gage set.

Pull the fan cover, pull the valve covers and spin it over check, and adjust as needed. The covers use an o-ring that should be reusable. Hardest part is going to be contorting my body to fit.

What size and make is you UTV? Also how many hours on it. Manual says check at 20 hours.

It's a coleman (hisun) 400. the engine/drivetrain & maine schedule seems to be identical to the 550/750s.

It's got a whole whopping 5 hrs on it. I had it for about 10 days before I had to go back to work on my ship. Be back home soon and planned on doing that and the first oil change in a couple more hours run time.

Makes total sense. It shouldn’t be a big deal to perform. I’m looking forward in doing it instead of having to trailer it to a dealer and renting a trailer. Not looking forward in being a contortionist to gain access and visually seeing the adjustment locations. A mirror will probably help.

      Massimo T-Boss 410 has lost all electrical power
      By robwork9
      Hopefully someone out there is a T-Boss 410 electrics expert or a Massimo mechanic is viewing this. I parked my 410 and it was working great. I came back a week later and attempted to crank it and nothing. Turned the key and no power. Figured it was a bad/low battery so I charged it. Still nothing. Attempted to jump start it and still nothing. Usually when I put the key in and turn it to the first position, the display comes on and I hear the ECU and other items boot. Now it is doing nothing. 
      I slowly went through the electrical system and found the main fuse attached to the starter relay, part 71602 (pic 1) blown. I figured replacing this fuse would fix my problem. It didn't. I then ordered a new starter relay thinking maybe that part had gone bad and caused the fuse to blow, but a new relay did not fix the problem. 
      I have found a work around for starting the machine. If I take one of the purple/black leads (pic 2) and insert one of them in the bottom right of the starter relay (pic 1 and 3) then the machine will get power even with the key in the off position.  I'm bypassing something but don't know what. I can use my right hand to hold the wire against the lower right of the starter relay, reach over and hold the brake with my foot, then take my left hand and turn the key and it will crank. As soon as I remove the wire from the relay the machine shuts down. I have even removed the power distributor box and it will still get power when I touch the wire to the relay. Of course this is not the way it should work but if I can't solve this problem somehow I may just have to rig a connector to the relay and bypass whatever is causing the electrical issue. Massimo has told me the purple/black wires on my model are not used.
      Any help in figuring what my problem may be or other items I can try?
      v/r,

      2022 Axis same as HS500 seat adjustment
      By Greg Kilgore
      Got a good deal from Lowe's on an Axis 500. Same as the Hisun HS500. So I've been told.
       
      Anyway the wife is 5ft nothing and has trouble reaching the break and gas pedals. I'm needing a solution for making an adjustable seat for her when she drives. But has to go all the way back for me. Or my knees will be in the steering wheel.
      Anybody got a solution. Also don't like the fact that the seats are held in by the plastic.

      Massimo T-Boss 750 hard starting
      By Byron Johnson
      Does anyone have a had time starting there utv.
      I have a T-Boss 750 and I have had to put 2 starters in and put heavier wire to the starter but it still has a problem starting. it will turn over and than die before it wil turn over again. could it be that there is to much compression that might cause this problem
       
      Thank you

      Kawasaki Mule First Service
      By rsar
      Just got quoted $770 for my Mule's first 50 hour service. Is it just me, or does this seem insanely excessive? I was expecting something in the $350 to $500 range and thinking that even $500 would be a little high. Is dealer service really necessary at 50 hours? At this price I think I'd like to shop around for a mechanic that could do it for half the price. I don't really have the option of shoping around for a cheaper Kawasaki dealer, as there is just this one dealer a reasonable distance away (30 min). The next closest olne is 3 hours away.
