Massimo Buck 400 First oil change


Recommended Posts

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?

Be sure you're turning it the correct way, counter clockwise to loosen it.

They are pretty tight from the factory!

One way I do is with my ratchet or wrench, and get A hammer and hit the end the end of The tool with it,that usually gets it done.

Can't help you with getting it loose.  But future oil changes would be much easier if you had a valve type drain.  I use the fumoto valve on all my vehicles when possible.  Makes oil changes extremely easy. No wrenches, just flip the lever.

Do you know what size to buy for the Buck 400?

Pull the existing drain plug, or an internet search will give you the size. Make sure there's clearance to install, for example, skid plate clearance. If extra length is needed to make the necessary clearance. Fumoto also has extension adapters. 

I prefer the short nipple version. Don't forget to also get the hose end, that connects to the nipple. Fumoto sells reasonably priced tubing also. But you can get that locally if you prefer.

      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,

      Does anyone have a had time starting there utv.
      I have a T-Boss 750 and I have had to put 2 starters in and put heavier wire to the starter but it still has a problem starting. it will turn over and than die before it wil turn over again. could it be that there is to much compression that might cause this problem
      Thank you

      Hello everyone.
      Here I am showing our Green Scout electric all-terrain vehicle.
      All-terrain vehicle 6 wheeled, electric, side-turning. Rides, jumps, dances, swims, but does not fly. The drive is permanent (but you can turn off any wheel arbitrarily through the controller). The power of each wheel is 3 kW at its peak, the total power is 18 kW. Speed up to 60 km / h. Since the all-terrain vehicle is electric, it starts from a place quickly, drives silently (well, of course, the sound from tires and shock absorbers does not disappear).
      The idea of creating such an all-terrain vehicle came after the experience of operating the Argo all-terrain vehicle. The main disadvantages of the wheeled side-turning all-terrain vehicle are low ground clearance, lack of suspension. To get high ground clearance and suspension, there are two outputs on mini all-terrain vehicles - either electric drive or hydraulic. The hydraulics had to be excluded, since at temperatures below -30C it does not work, plus it always flows. As a result, we settled on an electric transmission. Each wheel is a motor-wheel. Naturally, the motor-wheels were being finalized to be able to be installed on an all-terrain vehicle and to be able to swim. The battery is iron-phosphate, all information on the battery, the charge is displayed on the smartphone. Control of the all-terrain vehicle through the on-board computer. Bicycle handlebar controls. Braking either with the sides through a turn of the steering wheel, or with the gas pedal of all wheels at once.

      I have recently acquired a 2012 CFMOTO 500 CC side by side. The previous owner said that it ran great but had a gas leak by the throttle body that caught fire and ruined most of the parts on top. It also melted the cover and fan for the stator. Does anyone know of a good place to get all of these parts? I usually use Amazon for all my 2020 hisun parts, but can't really find the ones I need for this. If anyone has any ideas I would greatly appreciate it. Thanks in advance

      I acquired an older HISUN BIG BUCK 500 that hasn't run in years.  Little elbow grease and she's running.  I have a few more parts to switch out but when revving the engine over 4K the r light starts blinking.  After googling and seeing other people I replaced the rev limit switch under the air box and found the same issue.  I traced the green and white stripe wire back to the computer module and found no breaks in the wire and cleaned the connectors.  Still same issue.  I then cut the wire right at the plug and grounded it directly to the battery.  I can now rev over 4k rpm however the light still blinks and when in reverse the light no longer lights up.  Anyone else run into this?  Can R light blinking mean something else.....HELP, what am i missing?????

      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,
