Awesome. I use electronics cleaner on all sorts of electrical equipment, its great.

Like Kent said, replace the ECU..

StarTron, .I never buy non-ethanol! Another good thing about StarTron, you can’t over do it.

I have a 2021 Massimo T-Boss 410 and it needs the cv boots replaced.  Has anyone had to replace the boots on their T-Boss?  Does anyone know where to get replacement boots?  Are there boots for other ATV/UTVs that will fit?  The Massimo parts site only sells the entire axles.  Thanks

I have bought what few parts I have needed for my 2016 MSU 800  usually on AMAZON, EBay and here and there.  I would lik to say I have had very little need for parts in the 7 yrs I’ve owned it. Mostly items I consider wear items, I.E brake pads, axel bearings things like that. I did need an ECU onetime, very easy to find. I threw a quick search on google for Massamo cv boots and sure enough several jumped out at me on Amazon and eBay.among other places.hope this helps.   Oh, Benche probably fit also but a dealership will never admit it.

   Oh, don’t be surprised if you get a s.storm here about Massimo but mine has been great.

Sorry I missed your post.. I see you still arent smart enough to tell what sarcasm is.. and did you ever see me endorse.." SCHILL for ",  a specific brand ?  oh yeah, thats right you didnt.. but since you have no actual comeback with valid info, you do what democrats do and make something up, accusing others of doing what you do..  pathetic 

Oh so now you drag politics into it!!!  Oh, by the way buddy, I'm farrrr from being a Democrat!!!!  Talk pathetic!!!

Chris, thought I'd throw this out to will until more informed members help you out. There are some here that have more knowledge on these things than Myself. I own a 2016 MSU 800. In 7 yrs I have very few problems with mine. Mainly brake pads which I consider a wear item and wheels bearings a couple times. Mine has sealed wheel bearings as opposed to roller bearings that can be maintained, the only maintenance of sealed bearings is run them until they wear out and replace them!!

  On me machine if it gets to where it doesn't shift well it's usually the adjustment on the shifting linkage, which in my opinion is quite touchy, therefore it doesn't take much for it to get out of adjustment. 

Buy these things can be a handful. But as I learned a while back with Joe and others helping out and a little mechanical ability, which you obviously have it will work out!!  A great forum, so glad I found it and joined!!

Very interesting thread. Aefron88 and others have been a lifesaver to me, 2015 MSU 800. Just a comment, NONE of the UTV manufacturers give a rats bottom about the owner or mechanic...none of them. Friend has arctic cats, royal pain to work on OR get the right parts. Another friend had a Honda side by side, nice machine but weak front end assembly and again....pain to work on. Whenever we went hunting in the swamp he left his home and used mine because he said if he got tangled in downfalls (3-4" trees) he had broken several tie rod ends!!!  So like I said, he left his Honda home, which cost half again more than mine and we used the junk, Chinese Massimo!!! LOL

I have found Motor Cycle Doctor to be some of the best to work with..

all depends on the problem

Only if you have problems after it sits for a week or so.

if you run it for a hour or so a day like mine, no problems.

 Star Tron also does very well at preventing carbs from gumming etc.  I've cleaned too many carbs where the Sta Bil apparently fell out of suspension and gets sucked into the carburetor all at once.. doesn't run too well on only stabil.

 

 

 

Almost a yr later but I never buy Non-ethanol. But I do use Star-Tron. Your gas will NOT go bad if you add Star-Tron....unless you get water and water never did workload with gas. My portable generator has 2 yr old gas in it......with Star-Tron.  Started it a few weeks ago, ran it for half an hr, ran great.

Wife said UTV stopped running and cannot restart. I checked the battery, it was good. I checked the fuse box, no blown fuses. Whe I tried to start, the starter had a thump noise one time, and the starter relay wires were hot. I replaced the relay, nothing. I then replaced the starter and still the same symptoms. It won't start and relay wires hot.  Any ideas what to check next- perhaps ground strap of which I have no idea where it would be, or perhaps a new fuse box with new relays?

If it were my machine, (MSU 800) I'd take the screw cap off the end of the magneto, using the correct size Allen wrench make sure the engine isn't stuck, "froze". Can't say for sure on that 500 if that's how to check it. I'm sure there are some here that can tell you. Aefron88 for one.

I can’t imagine not wearing the seatbelt the way I drive

Thanks I’ll try that. Darn things smarter than I am. Of coarse that’s not saying much!!

No worries. Good luck getting her back together and let us know how it goes.

Had it back together several days now. Runs great, no leaks whatsoever. Only thing not quite right is sometimes when I stop it quits. Hit the key it runs perfect, probably some sensor not quite happy. Other than that it’s great. Going in the woods tomorrow, need to fill my feeder and clear a shooting lane on the lease. Thanks for all of your help.

I try to warn people of how Massimo treats customers.. many on here have had the same experience.. you tired of my posts.. ignore them.. simple click..   Massimo has sent schills to try to silence me before.. They will not succeed .. They are a rip off company and everyone should know BEFORE they buy one.. I wish someone had warned me.. I did not badmouth your machines.. I bad mouth MASSIMO.. not my fault you cant tell the difference 

Trust me Joe, I need and have no one sending me to do anything....I'm just tired of your sarcastic replies to questions I ask. Speaking of "schills" who sent you??

 My first post on this thread was simply  to suggest retorquing heads after cooling cycles, nothing about Massimo..   Or did you miss that?  I do not show up just to bash brands..  Obviously I praise HONDA and KAWASAKI because I see their quality.  if you cant see that, block me .. obviously you dont need my input and past experience with all the problems and solutions I have found on  these things .. But I ll bet others have benefited ..   BTW I dont need your permission to share my experiences. 

Well that's good Joe because I wouldn't give you permission! You say put YAMMAHA parts on my Massimo and it will be a better machine??  

Obviously Joe you're on an anti-HISUN mission. Just speaking for myself, I'm tired of your constant bad mouthing my machine!! You've made your point, get a life!

Thanks, I was thinking on doing that. Guess mine has a low appetite, 6 yrs old. You should retorque most any engine head after a few heat cycles.   Oh I know, Hisun is junk

Unfortunately there isn't a manual for that year on this site. 99% chance the spec is the same which is why I posted it.

Believe it or not all these hisuns are all very similar mechanically and have very few changes year to year.

Look thru the service manual and see if it looks like the same vehicle. If so you should be good to use it.

Oh I believe you are right and thanks for the help, I sincerely appreciate it!! Parts here today, we shall see how it goes.

No it’s a 2016

Changing head and head base gasket, rear cyl. Can anyone help with head bolt torque?  Thanks!

As you can tell. Sometimes (usually)I slip 2 - 3 hrs then wake up! Curse of growing old! Feel a little foolish, why not put the darn thing in gear, set the brake? Crack the nut, put back tdc and continue on??  Duh??  Be nice to know if it’s right or left though.  Thanks Joe.  

Remember, some people would complain if you hung them with a new rope!!
