Well i finally bought a NEW muffler for ol' Red. and Boy she sure is quiet now! You can hold a conversation, or talk on the phone with it idling. and much smoother sounding at full throttle. I like it! i finally found one on Rocky Mountain ATV for 165 with Tax. cheapest place i found. Of course not every project goes fine and dandy, the bottom bolt where the inlet to the exhaust bolts to the exhaust pipe (seen left hand side of picture) , the 10mm bolt rounded off... couldn't get my rounded bolt miracle socket too it, so i took my air hammer and put a chisel bit in it, chiseled a cross in it, and then chiseled up from the bottom, doing that broke the head off and the bolt knocked right out with a few light taps from a punch. I put anti seize on the new hardware.

Diesel engine may be better in his case for more torque, hauling 4 people plus any gear/load in the bed and hilly terrain.

I'd look into the Kawasaki 4010 trans or the Polaris Ranger Crew. I am biased towards Kawasaki for the build quality and availability of parts for years afterwards.

To find that out you really need to go to a dealer try them out... I would recommend looking at a Kawasaki 4010 Trans.

Most likely a low oil sensor saved your engine. If you know the unit is Full of oil, no harm in trying to restart it.

the issue with Massimo's, they've been made by at least two different manufacturers. Someone may have gotten a "X" made model, with no fuse box and was total junk, while you may have gotten a massimo made by "Y" made model which was built better mechanically and electrically.

Is this what your pump looks like? https://www.ebay.com/itm/402321304682

what Make UTV and what model?

Located in my post above yours

If it has seat belts, are they buckled? some of these have a limiter on speed when the belts aren't buckled.

Does it have a choke? if so i would be looking at a cable adjustment, to be sure it closes 100%.

This should be the correct manual,

I looked on the BBB, they aren't an accredited business, but they do have 1 review, Try this dealer locator https://www.hisunmotors.com/dealer/locator/

Welcome!

Did you ever get this worked out?

That's odd. When my grandad got his new Mule SX, the dealer said first service was 20 hours, that entailed engine oil change and filter and checking valve clearance, i'm capable of that so i did it for him. I think they quoted around the same. You could check and adjust the valve clearance if you were inclined to, but really don't need to check unless you encounter hard cranking or hear them ticking.

Hisun makes them for Lowe's.... read through the Hisun and Massimo forum. Honestly i don't think their products, nor there after sale services are very good. I doubt Lowe's would be any help if you needed a warranty claim, or tech help. I'd go with the Honda just for the fact of the unmatched reliable reputation they've built.

Mike at Pacific Eagle UTV should be able to fix you up. https://pacificeaglepowersports.com/kawasaki-pro-fxt-dxt-lexan-windshield/ If that's a little out of your $$ range, i'd have a look here https://www.sidebysidestuff.com/kawasaki-mule-pro-fxt-windshields-and-roofs.html

Hmmm. definitely a mystery. Are you able to run through a full tank of gas? i have on occasion seen the fuel pickup tube in the gas tank broken off/corroded. 610's don't have any low oil shutdown so that shouldn't be an issue.. Does it blow any (black or white) smoke out the tailpipe when it does this?

Yep, if you want electric, i'd go with a Club car or Yamaha golf car

If i cant find a USA part, i always look for Japan next. Denso etc...

Welcome! My Grandad purchased a Mule SX in 2020. Darn solid machine... but my ol' 550 keeps up with it just fine.

Yes, the website is still up, but the business is no longer in operation. I inquired about running boards for the 550, via email and phone, never got an email response and i get nothing when calling the phone number, finally i ran across someone on a hunting forum from Dallas who knew the owner, and said he had passed and the business is no longer operating.

just like you've had good experiences with a company, people have had bad experiences with the company, it happens all the time with different companies,
