Massimo 500 utv


Myerry

Recommended Posts

We have a massimo 500 utv we have changed the fuel pump (but you can't hear it kick on) we put a new fuel injector on and a new plug the thing will turn over when trying to start it but it will never really start or run. Can poor gas right down the throttle body and it will run for just a second and stop please help. Not sure what else could be the cause of it not wanting to start and run

If your UTV will not start or if you prime the throttle body and get it to run most likely it is a fuel pressure problem (fuel pump).  This is a common problem with all (big brands from USA, Japan and China) go down to the store and buy a cheap Fuel Injection tester and you will find that there is not enough fuel pressure.  Before you go ahead a purchase a new fuel pump check the connections and the grounds.

      Does the transmission share the crank case oil with the engine or does it have its own oil seperate from the engine?

      I have a Massimo 400 Buck that overheats and the antifreeze blows out of the motor everywhere! I don’t have to be doing anything but just driving through the field.  It only has 26 miles on it.  I don’t think the fan is turning to cool the motor.  Any ideas how to fix this?

      Just bought a Bad Boy Bandit 750. Need to change the oil and filter. Any suggestions would be greatly appreciated. I'm pretty sure this a Hisun 750 Sector even though it says it's a Bad Boy. I'll include pics soon.

      I have a 2018 Massimo Buck 400 with 278 miles. 
      Having issues with my brakes. Took the buggy hunting and when I let my foot off the gas pedal it pulls without pressing on the brake. I looked and the pads on all 4 wheels are all toast. The E-Brake hasn’t been on since I have had it. I am guessing it may be a master cylinder issue because all 4 pads are gone. They all seem to have worn evenly that’s why I think the master cylinder. Just got the machine used from a older couple and they said it sat for some time in there pole barn. Possibly the brake lines? Calipers? I took one brake apart and when I depressed the caliper it didn’t stay. Any help is muck appreciated.

      Hey guys! Newbie here. I'm an old man who's better with plowing a mule (4-legged kind) than these newfangled beasts. I, and a friend of mine, just bought new Coleman sxs and are having to finish the assembly. I've been reading on this site and I'm falling on the mercy of you experts. The only way I'm an expert is that an "ex" is a has been, and a spurt is a drip under pressure. LOL First off, the 2 buggies have no ignition switches. They seem to mount on the dash, not the opening in the steering wheel shaft cover, so we ordered new ones that are supposed to fit. They are 8 inches long, and have a 4-wired white plugin which is slightly rectangled when looking at the end of the plug. The trouble is there's nothing to plug into. There is a three-wire grey plug close enough to reach the four-wire plug, but of course, they are not compatible. 
      Secondly, the blinker, light, ect. unit on steering wheel just spins around when touched. I see no way in heaven or earth to secure it. I've looked at a diagram on the Powersports site, but can't detect how it mounted. Fellows I'd be so grateful for any help with this. Me and my mule will even plow your garden for free, for your help. LOL
