Need advice on Massimo Buck 400 problems - issues

Recommended Posts

I bought this thing last September.  The farm store was extremely nice. 

But, forget asking for any advice like in the old days.  They only SELL them and tell you to call the Dallas tech person.  

During the week days - I don't have time.  

Oil change:  If there is someone who can tell me why the owner's manual (and the internet) says it holds 2 and 1/2 quarts of oil but, my mechanic could only get 1 and 1/2 quarts in it and there is NO oil filter.  

Please help.

If you have the same engine that I have in my T-boss 410, there is no oil filter. There's a strainer above the oil drain plug. It comes out, clean it (or replace if necessary). According to my owner's manual, it holds 1.4L of oil. The conversion to quarts is very close to the same measurement.

      Has anyone found aftermarket side mirrors that work with angled bars on the 800sx other than the super expensive factory ones?

      Hello All,
       I am trying to find a Scanner that is works for a 2016 MSU500. I found the Tiny Scan TS301 that looks like a decent Scanner but so far have not been able to get confirmation that this works on and older model. It has been stated that it works on the 2019 and newer but not sure about older models. It appears that the ECM/ECU/EFI modules are likely interchangeable between a 2016 and the newer 2019 and on but not sure of the Scanner. I am waiting for feedback from Hisun on this issue right now.
       If this unit is not usable for my model year has anyone found and a Diagnostic Scanner for the older machines, one that works and is Affordable?
      Thanks for reading my post and any information that you may have to share,

      What type and brands of insulation do you use in the cabin, floor and engine compartment of your Massimo and related 4 by 4 UtVs specially Massimo Buck 400s?

      So i have a 2011 EFI 700. the SxS will crank right up everytime without any issues. If i let it run or ride it for about 10 mins it will shut off and then it may turn on if i am lucky but most time i have to let it sit for like 3 hours and then it will run again. i have done the following
      -New fuel filter
      -New injector
      -New spark plug
      -New coil pack and plug wire
      -New air filter
      Also could i get a grizzly 660 engine and put in it or would it not work.

      Has anyone in this group installed power steering in a 2019 Kawasaki KAF400PKS. If so, please advise on what type of power steering and how it went. Thanks in advance.

      It has done this since day one that we purchased it from Tractor Supply. I contacted the service man that Tractor Supply recommended and he told us that there wasn't anything he do to help us with. Has anyone had this same problem and can offer suggestion on to correct this issue ? It would be greatly appreciated.

      I just bought a new buck 400x golf and just signed up to this forum. Lots of good info and glad to be here.
      I took off seat to see the engine and noticed a black circular pipe just sitting exposed  leading to the engine bay. As well as a rectangular pipe coming off crank case and possibly even an electrical harness or two with nothing obvious to plug them into?
      Does anyone have the buck 400x golf and take a picture or look in their engine bay and let me know if this is normal or if there is something missing on my cart.
      I reached out to massimo and let them know that it was unusable if this is actually an important missing part it probably shouldn't be driven, they said I should hear back in 3-5 days but that they are very busy. I figure if one of you has one you can take a look for me and I don't have to wait around on massimo to answer me on what a normal engine bay looks like.
      Thanks for your help,

      I was told by the Massimo dealership that I need to change the oil in my buck 400 side by side after the the first 25 miles as this is the break in period. I’m having a terrible time unloosing the drain plug 😩.. any suggestions?

      I purchased a Red Massimo Buck 400EFI recently from Massimo Motor.  It was very simple to purchase on line, it was quick and painless.  After placing my order, I got a call from the Massimo Motor Customer Service Department (Eddie).  He wanted to confirm my order and he let me know that they were building my UTV and gave me an estimated date of completing and delivery.  Upon completion of the unit, Eddie reached out to me to let me know that it would be shipping and that I should expect it within 7 business days of his call.  I actually received it 3 business days after his call.  The truck driver was very polite and helpful.  We got the UTV off the truck and away I went.  We have a small tree farm and we needed something that we could use to maintain our little farm with ease.  The Buck 400EFI performs as expected.  It runs really well; it looks good and the most important thing about it is that my wife loves it.
      A few days after receiving my UTV, Eddie from Massimo Customer Service called to make sure that we had received the UTV with no problems and to see if everything was OK with the unit.  He told me that if anything were to come up with the unit, to not hesitate to contact him and he would help us resolve any issue that may arise.
      I am very happy that I purchased this UTV from Massimo Motor and IF I had to do this again, I WOULD in a heartbeat.  Eddie at customer service is outstanding and because of him, I would recommend anyone who is interested in purchasing one of these UTV’s, to ask for him.  He will take good care of you.
      Very Happy Customer
