I own a 2020 T-Boss410 I'm having problems with it over heating with it just idling for maybe 10 minutes, I have checked the fan and it works. I wired the fan up to a switch so it runs all the time and it still over heats within 10 minutes. Anyone have suggestions?

I would guess that there is air in the coolant. There are bleeder screws for this, and you have to raise the front end somewhat. I have a 2019 T-boss 410. Haven't had any trouble with it so far. You may also check the thermostat to see if it's working properly.

Well, I can't seem to locate that info. I had it, but now I can't find it.

There's a section here that has downloadable service manuals for the T-Boss 410. You can try there, but I don't know if there were any design changes from the 2019 to the 2020.

Is it a Linhai engine?

ahhh... the dreaded Massimo leaky head gasket syndrome ... I know it well .. Exhaust gas leaks into coolant blocking its flow with a big air pocket in the head .. Coolant does not circulate.. overheats.. .....when the hot indictor shows, is the radiator cold?

I wouldnt bet on that.. ITS MASSIMO! ...Is your radiator very hot when engine overheats?  If  your fan is running, and radiator is not as hot  as engine its either head gasket or Thermostat is stuck closed if it has one..   Just my experience with their engines

      2020 Tracker 800 sx front end noise
      By Karlibob
      I have a 2020 800 sx with about 16 hours on it.  From day one I have heard a clunking noise from the front end going over bumps.  Has anyone else experienced this?  Also this past weekend while out riding I heard a noise that sounded like the dump bed bounced three or four different times, again has anyone experienced anything like that.  Thanks, gary

      Hisun 700 won’t start due to Break switch

      the break pedal seems to not fully throw therefore it won’t engage the switch in order to start. 
      it throws enough to stop the UTV but not enough to engage the switch. 
      I used it this morning, started fine, did some work then shut it off to talk to a neighbour and it wouldn’t start after. I can hear the injectors working but the break pedal doesn’t seem to go all the way down.

      2021 Massimo MXU 1000 Runs Rich
      By ToughLuck
      I have a 2021 Massimo MXU 1000.  Last winter the front drive shaft sheared off inside the motor and it was cheaper to buy a new motor than to take it apart in order to remove the front drive shaft that was broken inside the case…
      Now it is running rich, seems to maybe be geared too high, does not accelerate well once you hit about 28mph.  I’ve replaced the O2 sensor.  MAF is next (I accidentally ordered the wrong one, but when I removed the old one you can clearly smell fuel).  
       I’m not a motorhead but I can turn a wrench.  Any ideas how to get this motor optimized?  The motor has about 300 miles on it.  I broke it in as recommended in the manual.

      Kubota RTV-XG850 Sidekick shifting into nuetral problems
      By Paul L
      When I am driving at 30 to 40 mph on the highway, the display will change from H (high) to R (reverse).  It does not actually shift into reverse, it seems to shift into neutral and starts losing speed and the gas pedal has no effect.  After the rpm/speed drops for 5 seconds or so, it changes back to H and runs fine for another minute or so.  You have to try to drive it at less than 5000 rpm or so, to try and keep this from happening.  Any ideas on what the problem might be?  It only happens at the higher speeds.
