ALL HISUN ENGINES... even the Factory rep in Dallas told me they stopped using the HISUN engines.. in 2019 started using Lintao engines because the HISUN are junk and prone to problems .. and the Lintao does not have the overheating issues Hisun has.. So I asked what they were doing for those of us who bought their HISUN models... HE SAID... NOT MY PROBLEM .. I said you should repair or replace them.. he said NOT GONNA HAPPEN ... I recorded the phone call.... Massimo is a horrible company

mine only has speedometer, tachometer and fuel level gauge ..the rest is just warning lights .. temp...battery etc ... btw, when I picked mine up at shop, he had 3 others in there for overheating issues... this is a common problem with these machines

buy a cheap infrared thermometer and check it ..thats what I did

I hope the bugs are worked out finally .. But I thought that a couple times before, only to be disappointed on the trail .... There is no thermostat in mine, I m trying to keep the engine temps as low as I can.. NEW CYLINDER HEADS AND LABOR ARENT CHEAP and shops willing to work on these machines are very limited. .. . my original was cracked from all the overheating or it came cracked from Hisun.. .. We did have fun this weekend as it performed pretty well.. I do recomend you check the temps your fan is set to turn on/off, and if its high like mine. BYPASS THAT SWITCH to run 100%. I would hate to see you learn the hard way.. Mine is not the only one blowing head gaskets.. there are many .. Good Luck.. hope you get to enjoy it..

Yes fan was operating ...The fan would come on but was Factory set at 210* and would turn off at 190* at the switch on the radiator on the return side.. .. so how hot was the engine??? .. WAY TOO HOT... . New Head, new gasket, new waterpump , oil change .Repairs are now complete, .........And I ran it all weekend and was pleasantly surprised it had no issues except it now developed an exhaust leak.. It did not overheat AT ALL, with fan running 100% of the time.. The exhaust leak appears to be the exhaust pipe is cracking just a few inches from the head.. I put about 30 miles on it on trails on the RIVER . .. Also, I pulled a friends Kawasaki SXS out of a big mud hole on the trails with mine.. I made it thru, he got stuck

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

Hopefuly you wont have the same problems... I do HIGHLY RECOMMEND that you bypass the fan switch and make the fan run continuos with key.. It will keep the masive heat these things generate ,down and hopefully save you a head gasket repair.. Good Luck

haha.. no, the idiot bought the new Massimo 400 for $9900 anyway... .because, he said.. IT HAS A WARRENTY!! hahahahaha .....oh well, you cant fix stupid.. at least with mine, most of the problems have been remedied, as it currently is running perfectly!..and it was a cheap investment ... Going to the River this weekend, and its going to be upper 90s, so we shall see how it holds up... cheers

Well, I have managed to dissuade several prospective buyers at both Home Depot and Tractor Supply.. After telling them of the constant problems and pathetic NON-EXISTANT service from Massimo , they went off to look at Honda and Kawasaki .. So that gives me a small amount of satisfaction at least.. One guy simply did not believe me, so I offered to sell him my 2017 Massimo with 312 miles on it for $4900 .. THATS HOW BAD I WANT A HONDA .. He came and looked at it... Hes thinking it over .. It is running good at the moment ..

Has anyone tried using an external electric water pump on these machines? I watched a video on youtube of one installed on a 1000 cc side by side that had chronic overheating issues in hot weather.. He claimed that after installing a Prius electric automotive pump from junk yard, inline in the inlet hose and bypassing fan temp switch, that the engine never overheated again. .. I am considering trying it on mine...................... Anybody else done this? .................. He did not say if he removed the mechanical pump or not.. would it pump thru that pump?

Well, I got it back.. Its running fine, but it always ran fine ..TIL IT OVERHEATS ................. so far , one day and its still working... Maybe I can get more than 10 miles this time before it breaks again ...

Great job.. Hope it runs well, for a long time.... I wish I could work on mine, but 3 back surgeries prevent me from doing mechanical work anymore.. It kills me to have to wait weeks while the only shop in the state that will work on Massimo machines, slowly does the work... Still waiting on mine now..

This Saturday I will bring a camping chair and sit in front of the Massimo unit at Home Depot all day or til they run me off.. Hopefully I can save some prospective buyers the misery of owning these piles of s$#T .. Just my way of saying THANK YOU to the worst company I have ever dealt with

Welcome to the club of dissatisfied Massimo owners.. My 2017 only has 312 miles .. thats all I can get in between 6 trips to repair shops and waiting months for parts.. The Owner in Dallas admitted to me in email that the HISUN engines are junk, they dropped them and use Lintao motors now.. And btw..NO THEY WONT FIX THE HISUN JUNK under any conditions... .. I tried BBB , they are a joke.. Might as well leave a bad review on Tractor Supply.. [ They will delete it ] I did however manager to change several buyers minds at Home Depots and Tractor supplys .. After I told them of my experiences with HORRIBLE customer support, and how bad these units are, they all walked away from pursuing any purchase

On Massimo , the standard code spells out .....S U C K E R .... they are absolute junk ... mine is a 2017..and is in the shop for the 6th time since February of THIS year..

At least you got it to 1600 miles.. I have a 2017 Massimo I bought in march of 2018 BRAND NEW from TS.. it broke on the first day....it now has 312 miles.. and its in the shop for the 6th time since February of this year... THEY ARE ABSOLUTE CHINESE JUNK ... Dont buy one even if its 50% off ... YOU WILL REGRET IT .. I saved an email from the Factory Service REp admitting these engines are garbage , ...they had to source another Chinese engine maker and they are refusing to fix these ..

wow... looks like the diesel washed the oil off and thats the result? I am shocked the cylinder walls dont look like that too..

same thing it always does everytime I use it... same thing Massimo is world famous for....IT OVERHEATS … Dropped it off this morning.. I ll let you know what they find

well, theres no joy in MUDDVILLE tonight..it took about 5 miles on the trail , and BAMM .. we are back to square one... I am just disgusted with this pile of crap

any progress? have you tested fuel pressure/ The diesel may have damaged pump seal or filter material...

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

we[l, shop called, parts came in, installed running good, but now waterpump took a crap.. so here we go again

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

no, the shop doing the work ordered it.. I just called him, he says he got shipping confirmation finally... be here in 3 days... maybe .. any luck resolving your overheating problem yet?

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
