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!

Hi all, I own two Axis UTV's. Last year I purchased a 2022 Axis 500. I had a mechanical issue with the shifting forks after only 50 miles. I contacted Axis/Hisun warranty dept. That were very helpful and willing to send out a representative to see if it was a warranty issue that fell under coverage. Since I live in an area that does not have authorized repair facility within 300 miles. A really nice guy drove all the way from West Virginia which was 4 hours away. He determined that the console would not stay seated in position and while driving it, the console would jump forward and knock it into the wrong gear causing the shift forks to become bent. It was then picked up a few weeks latter to be repaired in Richmond, Virginia. It should arrive home soon.
Now to my question. After the 2022 Axis 500 was taken for repairs, I bought the 2024 550 Axis. I bought the first one to take my son who is disabled from an extremely rare disorder that requires daily care to get out of the house. There are two things that give him joy, music and going for rides. That is why I purchased the first one, However because it had bucket seats and the engine was between the two and was too loud even though I deaden the sound and put a quiet muffler on it.
I then decided to purchase the Axis 550 for the great updated features and the bench seat, I will be buying the complete enclosure ad on's offered by Hisun. Since it does not come with a heater (Axis 750 does) I was wondering if anyone knows what heater is part of the 750 edition. There was a photo that showed a Firestorm brand, however I can not find what variation it is. If anyone knows what a Inferno heater would be correct for the Axis 550. I would like to install it this Winter to take Justin riding on the farm. Any help would be greatly appreciated. Brent

Has anyone installed the magnum tuning chip? Is it worth it? Noticeable difference? I have a 2021 Axis 500.

2021 Hisun Axis 500 UTV (From Lowes)
Will NOT START
MY apologies if this is to much info just wanted to give yal the most information possible for help.
I'm a so called diyer. An Electrician by trade 21yrs. I got my S×S from my last job. The contractor purchased this S×S for this specific job brand new, from Lowes. They used it for hauling materials, tools, & a little bit of anything you can think of on an Industrial type job site.
I remember getting on the SxS one time & pushed the gas petal all the way to the floor & SxS had very little power.
So anyway ,when the job finished up back mid July this year (7/2024) , I asked the contractor what they was going to do with it. I was told to take it. Otherwise it would go to the contractors yard (storage yard) & most likely rust away.
Took it home washed it , it had a heavy coat of dust on it & in it dust was every where. My helper & I had to push it on the trailer to get it home. After washing it throughly I let it sit & dry out for a good day and half, maybe 2 days. Before trying to start it. NO START. Will turn over & try to start but thats it.
So here's what I've purchased & installed. New Air Filter, new spark plug, new air idle control valve (AICV), new throttle position sensor, new throttle body, new oxygen sensor, new digital dash speedometer/fuel gauge/clock.
Also drained the old oil & gas & replaced with new oil & 93oct. gas. I should probably mention that I've changed the AICV twice. The 1st time I changed the AICV I was able to get the SxS started & let idle for at least 10-15min. Drove out of the garage, with very little power, turned it around & barely got it back in the garage.That was the one & only time I've been able to start the SxS. I've also cleaned the Throttle Body and & intake with TB cleaner. So after that the AICV was making weird noise so I pulled it out & tried cleaning it, pretty sure I messed it up. So I purchased a Throttle Body that came with new AICV & TPS. Still NO START. I've checked the fuel pump & the fuel injector. I took the injector off still hooked up to wiring & turned the key over, the injector sprayed a lot of gas out kinda the size of a volleyball. I've also checked the clearance gap on the intake & exhaust valve. But today 11/2/2024 I'm going recheck spark plug gap & the valve gaps. And alot of other checking. Would the driver side seat belt have anything to do with it not starting?? I know the driver side seat belt has to be in gauged for full throttle "going fast". Thing is the drv. side seat belt will latch but feels like might be messed up inside of it. Tired opening it up but to no avail. I've never had a S×S or 4wheeler so I was really excited when I got the S×S,not so much anymore. I work on & fix my own vehicles usually no problems. But this SxS is kicking my ass.
So if possible & someone could help me with some ideas or tell me what Im doing wrong or did wrong, I would greatly appreciate it. Thank you for reading thus far.
