still waiting on parts …. talked to 2 other shops, both now refuse to even work on Massimo products because parts take so long and if its warrenty, 4 months to get paid is ridiculous .. they wont touch one anymore .. its just sad … Talked to an ATV /UTV engine  Rebuider , he says he thinks one of his rebuilt  Rhino engine would work on it , if not, he would let me return it.. So if this pattern continues,  RHINO here I come

Not yet.  Just got off phone with the shop trying to get it in.   Im pretty sure it is same issue as you either a gasket or head.   Thing runs fine with no signs of a problem other than antifreeze disappearing and then overheat.  Sadly I love the machine just not the headaches.

well, when we get both fixed, maybe can go riding together .. for about 30 minutes till they break again ..lol  ….Its really sad, it runs great for 20 -30 minutes.. then overheats and will not cool down  .. also we   have bypassed the temp switch on radiator to make fan run continuously now when key is on .... maybe that will help some by keeping the temps down all the time .. You might consider it too

Waterpump appeared to work before but was weak after new head install.. Did it cause the head problem? who knows?  EVERYTHING is  replaced now.. Got it back this morning.. drove it for about 40 minutes around my yard, but that's only 2 acres.. did not run hot.  RAN PERFECTLY!  has more zip , maybe it was losing compression. .. NOW, with the fan running 100% , the engine seems much cooler and way less heat from behind seats ..  . Tomorrow I ll go to my camp at Whiskey Bay on Sherburne Refuge.. I ll put it to the test there, got about 15 miles of trails to ride for UTV ,ATVs …. HOPEFULLY  I can get another 300 miles out of it …   Any progress on yours?  I would check pump and bypass fan switch.. Good Luck

Well fellows, there JOY IN MUDDVILLE TONIGHT.. I ran it all day saturday and half of today.. it was 95* outside.. It ran perfectly, and NEVER OVERHEATED!!!  Finally after months of frustration, and trips to the shop, it is working properly  .. We do have the fan switch on radiator bypassed to run continuously when key is on.. Theres far less heat coming up behind the seats now.. It did develope a small exhaust leak, but I dont even care ..  cheers

Good Luck... btw, took mine out yesterday again to the trails at the River... ran absolutely perfectly .. never got hot at all with fan running 100% now.. and I dont have all that hot engine air coming up behind the seats now..  And it was brutally hot outside. in the swamp .... 96* with a 110* heat index.. ran at least 25 miles... My mechanic did a good job.. hopefully this will end my problems from a couple years ... NO THANKS TO THE "EXCELLANT" SERVICE DEPT AT MASSIMO RIPOFF MOTORS .... ps  I removed the winshield  completely ,,, MUCH BETTER FOR DRIVER

Grewt to hear!  I just dropped new head and water pump off at the mechanic.  He is swamped but hoping to get it back in a week.  He is going to get a Yamaha gasket and see if it will work in lieu of the Hisun.   Fingers crossed.  Did they figure what caused yours to go bad in the beginning?

Well, another weekend of fun in the sun.. right after Hurricane Laura theres lots of mud! and the damn thing did not run hot!!!  WOO HOOO  finally working properly and so far appears RELIABLY!  And once more I would like to give a great big  middle finger salute to the ahos at Massimo Motors Service Dept who refused to help me in any way...

I thought about that too, but its running so much cooler now I m not worried.. Even the heat that used to come up behind the seat is gone ,... Good Luck, and enjoy if it works.. They are a lot of fun when they run right

      Got a 2021 Axis 500.
      I'm needing the head bolt torque specs.
      Manual states 38nm.
      But saw a video Hisun put out on YT for a 550 stating 50nm + 45° turn of wrench. Didn't think they would be that much difference on a 500 and a 550.
      Seen another YT video on a 2013 500. He did 38nm.
      Really only want to do this job once and done. And done correct.
      Anybody got the answer?
      Going to start this rebuild in a few once this weather brakes. Flooding and then snow and cold here now. But spring is around the corner and the wife has to have this fixed or a Honda pioneer may be parked in driveway soon. She has to be able to ride.

      I just purchased a 2024 Bad Boy Bandit 750 but the owners manual is somewhat confusing , does anyone know what kind of oil I should use ? Manual say something about wet brake oil which I am totally unfamiliar with ! Any help will be greatly appreciated !

      Have a Coleman UTV 400 that cranks, runs, drives well until it gets warm and is put under load.  Light throttle or full throttle it doesn't bog, but it will cut out mid throttle if you move the pedal quicker than it seems to like for example when you're getting ready to go up a hill, but if you immediately floor it, it will do just fine and not cut out.  It's random if and when it's going to do it, but is consistent in that it happens only when hot/full operating temperature.  I've replaced the injector twice, same with the spark plug and tried different heat ranges (NGK 7,8 and 8 iridium), replaced the fuel pump, adjusted the valves, checked air filter which is like new, changed the oil, replaced the fuel filter.  No check engine light.  I don't have a code reader for this.  Initially I thought it might have a head or head gasket issue as when I got it, the oil was over full, very runny like water milky and it was smoking.  I've changed the oil since then twice to clear and clean everything out, and it seems to be good.  Coolant stays the same level and so does oil with no changes in consistency or need for adding more. Had I think 7-9 miles when I got it and now has about 77.  What should I try or consider next?

      Hi, 
      New to the forum. 
      Came here looking for some experienced UTV users who can enlighten me about which brand should I pick for my very first UTV or SXS. 
      I'm between 3 brands and 3 models: 
      *Kawasaki MULE PRO-FXR   1000.
      *Yamaha wolverine rmax2. 
      *Can am Commander XTP. 
      The use I'm willing to give it is mostly to go to the range with my wife, load steel targets and all our shooting gear, we shoot a lot, rifles, Shotguns and Handguns for practice, training and competition. (Range is about 10 miles from home) 
      But also I want something that I can take to the trails and have fun on dirt, mud, rocks, puddles or creeks. 
      Any objective information will be appreciated, specially which is more reliable and durable. 
      Thank you and happy 4th of July.
