Hello everyone, any help/advice would be greatly appreciated. Helping my father with his 2018 massimo 500 4x4 side by side. He uses it to feed all the horses and cattle. As of now the only way I can get the dang thing to start is to take the fuel injector and hold it about a inch away from the head boot, start turning it over and as it starts up I just press the injector all the way in. I thought this was a air problem so I replaced the idle air valve. I also replaced the fuel injector, spark plug, and adjusted the valves not that long ago. I thru a new computer on it as we had a extra on hand. It is running pretty good just won't start without that trick. Does anyone have any ideals what the problem may be?

      2021 Axis 500 4 month Review
      By mac66
      I bought a used 2021 Axis 500 last April.  Low mileage and got it for considerably less than what they go for new.
      The first thing I did was change the oil/fluids and also put a new drive belt on it.  The only other thing I did to it was add a rear vinyl window that zips open and rolls up to keep the weather off.
      I used it on my 52 acre property to check trail cameras, service the food plots, haul fertilizer, seed etc etc. It's has a good size bed and is not too big or small.  It has worked well as a utility vehicle. 
      Other than using on the trails working around the property I haven't used it much off road...at least until last weekend when I went on 74 mile group ride around the county. In my state it's legal to ride on any road that's not a state or federal highway. The group started in town, rode about 30 miles on back roads to the state ORV trail system. Then did about 20 miles on the trails and then headed back via back roads to town.   
      It had rained for 2 days straight prior, so the trails were one mud hole after another.  It was very challenging.
      The good...
      -It worked fine, never had any kind of issue with it since I bought it.
      -It kept up with more expensive machines on the trails. I was the only one with a CCC (Cheap Chinese Crap) machine.
      -Fairly comfortable to drive.
      -The roof, windshield and rear window kept most of the rain off when it started raining in the afternoon.
      -Okay, I cheated. I peeled off the AXIS 500 stickers on each side. Everybody in the group assumed I had a Rhino. They didn't ask, I didn't tell.
      The not so good...
      -The horsepower rating on the 500-cc engine is 24 hp but it seemed underpowered. While I could go about 35 mph with the pedal to the metal on pavement and hard packed dirt roads the best I could do on loose packed roads was 27 mph. I had trouble keeping up with the others in the group.  It also bogs down on inclines in high gear.  On the other hand, in low gear and 4wd I didn't have any problems going through mud or sand or up hills.
      -It is LOUD! Had to wear shooting earmuffs to keep my ears from ringing while riding. Going to have to address that.
      Overall Impression...
      I was impressed with it on the trails, and it is a good utility vehicle for working around the property. Considering what I paid for it I am very happy with its performance.

      2015 Massimo 550 Throttle Position Sensor issue
      By TexAcoon
      I'm looking to purchase a 2015 Massimo 550 that might have an issue with it's throttle position sensor.   
      From the fella selling this UTV, he claims its to set the idle on fuel injection because the engine will not stay idle or when it starts sometimes it idles too high.
      My Question if anyone had any issues with their Massimo 550 and if it was actually the TPS or something else that would allow the machine to idle correctly.
      Thanks!

      Losing Fuel / Prime 500cc
      By Buddee
      2010 Hisun 500 - Carbed'.  She sat for about 3 weeks since last use.  Couldn't get it started.... has spark but plug was not wet.  Bought new plug, cleaned the carb, confirmed fuel pump (pulse type) is working.  Still nothing.  Put gas in the plug hole.... started right up and idled as normal and drove perfect.  Used it for the rest of the day without issue.  Tried to start again next morning.... same problem.  Poured gas in plug hole again.... started up and best kind again.
      Anyone have any insight to what's going on?
