These machines seem to have a lot of trouble with the one way bearing. Great video.

Just bought a Hisun Axis 500 UTV from Lowes yesterday. Build year is 2022. Great video's BTW. Is there a rebuild manual anywhere to buy? Thanks, Brent

I personally don't have one for the newer model. You might just try to contact Hisunmotors.com they should be able to sell you one.

What’s most common problem if the benniche 500 is smoking heavy then gets better after running a min is that the rings? And I just took it out last weekend and ran it for 10 mins and there was a weird fluttering sound and it died and would not start almost if there wasn’t any compression. I’m going do a compression test soon.

[@limitlesspowersportsservic3394]

Usually if it smokes on start up just for a few seconds that's an indication of bad valve guide seals but they are very well known for wearing the rings out & smoking too. I would also do a leak down test & that will tell you where the problem are. If it's rings are the vavles. I would also check the cam & Rocker arms for wear. Very common issue too

@@limitlesspowersportsservic3394 thank you for the response and taking the time. I’ll look into those

[@davidcasey6181]

They do not stock the diagnostic tool that I could find.

[@limitlesspowersportsservic3394]

Might have to call massimo directly to get it ordered.

A co-worker said I could have his 2012 yardsport ys 400 XLT 4X4 utility. Says it has reverse problems. It’s been sitting for 2 years. I’ve watched your videos on 500s or larger UTVs. Are the 400s close to the same or are they quite a bit different?

[@limitlesspowersportsservic3394]

They are different but not so much that you can't take some of the knowledge from the 500 & apply it to the 400. When you say it doesn't have reverse, does it even shift to reverse & does it shift to all the other gear ok? Alot of the time it's just a shift linkage adjustment.

@@limitlesspowersportsservic3394 I was told that it just ran really rough when it was put into reverse(engine wise). He said it drove just fine in forward gears. I don’t have it yet. Apparently it’s buried in a big snow drift and he hasn’t got it pulled out yet. Basically snow drifted over it where it’s at.

[@limitlesspowersportsservic3394]

There is a wire on the ecu that you can un hook that should clear up that problem. Shoot me an email at [e-mail] & I'll send over the schematic

@@limitlesspowersportsservic3394 I finally got the ys 400. Got rid of the 2 year old gas in the tank. Had to shorten some cracked gas hoses and replaced crumbling fuel filters. I’ve put gas in the tank and slapped in my riding mower battery. I can get it to run for about a minute, but then it dies and gas runs out of a hole near the top of the carburetor. Also the exhaust pipe gets supper hot(really red). I was wondering if you could share any thoughts.

[@limitlesspowersportsservic3394]

Well since yours is the carburetor modle, it sounds like the fuel needle has gone bad. You need to probably do a complete carb clean & rebuild. It's a good possibility the the reason your pipe is getting so hot really fast is due to unburned fuel but also some of those units have that issue too. So I would start by cleaning the carb & testing it then if is still over flows with fuel I would rebuild it are jist buy a new carburetor.
