So with seat belt on I can only get up to 20mph then it starts bucking until I get under 20 again. Diconnected the seatbelt and same thing. Reconnected seatbelt and unplugged speed sensor. Zoom..it flies. But now I have no speedometer. I have a new speedometer sensor on the way..any other ideas?

I have a 2021 Axis(Hisun) 700 from Lowes. Will not start. Checked starter, solenoid, spark plug and fuel pump. Everything seems to be fine. The motor turns over and will try to start but just will not. Battery is also good. Frustrated!

Can anyone please tell me or send a link as to how & where to hook up a code reader to my 2021 Hisun 500 Axis. I have a 6 pin to a 18 pin adaptor and the blue cord VAG KKL adaptor .Just not sure where or what to hook up to. Can I use your typical vehicle code reader or do I need to download something on a laptop or PC???

All mid 2008 through 2014 Polaris RZR 800 series have a big problem with the rear differential pinion nut backing off, allowing the pinion gear to shoot into the rear differential, destroying the rear differential. This has happened with machines with as little as less than 100 miles on them! Reports indicate that there are no problems, nor warnings, until the rear differential grenades, locking the rear axles solid! This requires the machine to be lifted onto a trailer, to be transported for rear differential replacement, as it destroys the case. After failure, rear differential replacement can be quite expensive: labor alone can run from $800-$1200 and a new OEM Spicer rear diff, if you can find one, can run from $1700-$2500! So, if you own any Polaris RZR 800 series between the years of 2008-2014, I recommend that you do this repair before further use of your machine. personally, I have grounded my machine until it can be done. Please check the online post for your own awareness.

Just received delivery of a 2024 AMP Pro. Thought I'd start a thread with my impressions as I use it and learn more. There doesn't seem to be a whole lot of real-world usage information out there on this model. Hope this will help others as they research.
Intended Use Cases
Fire mitigation / slash removal from a 5 acre forested and well-gamble-oaked property. The previous owners thought as much about fire mitigation as I do about fashion: not much. Snow removal Stump pulling General hauling (rock, lumber, etc.) Weimaraner energy depletion. Wasn't an original use case, but a nice added bonus. Experiences So Far
Wasn't impressed that two of the bumpers on the underside of the bed where it sits upon the frame were missing. The metal on metal contact has damaged the powder coating and the frame. I expect a little better QC.
I've only put a few hours on it, so not a ton to report on usage. It isn't quiet; it's silent. I can't even detect an electric note from the motor. I removed (and subsequently replaced) the motor cover noticed that the motor is German and made by Schambuller. The motor controller is Italian and made by Dana TM4. Given the operating specs of both I found on the web, I suspect both are higher quality than the previous Navitas (which is supposed to be decent). The motor is rated at 25 hp and 71.5 lb-ft of torque. It feels very powerful. All the torque is delivered instantly, if desired.
The bed is huge and has an electric dump as standard. Great feature but would like it to go up a bit more. Probably not feasible from an engineering perspective, but I want and I need ;).
Power steering is nice, but vague. Probably common to many UTVs, but I am accustomed to more direct results from input. Plan early and plan often.
In our first full day of usage, we hauled about 1/2 as much slash as the entire rest of the year when I was doing it by hand cart. I may get fatter, but I'll also get more done. After a few days of usage, the battery meter has gone down by 1/10th.
Until next time...
