2020 Kawasaki Mule Pro DX Yanmar Diesel Too Loud


Recommended Posts

Just purchased a 2020 Pro DX  with Yanmar diesel. Had a 2007  3010 Trans Diesel I traded in. My problem is that the new machine is so much noisier  than my old one.

Has anyone had any luck in quieting down the noise? Sound proofing.?...changing the exhaust routing.?...the muffler? Any ideas or solutions would be appreciated.

My diesel mule is extremely, and uncomfortably loud. But it's really loud at the intake, more so than the exhaust. Of course that intake comes through the roll bar, which is right by my ear, but still...

My solution was a rear window, and lots of insulation beneath the seat. Now the noise is re-routed. And much more tolerable. 

Mine is a typical old style s×s, so that approach probably wouldn't work on one of those new style dune buggies. My point is that you might need to look at deflecting the intake as well.

I ended up getting  Dynamat used for carhood insulation and installed it under the bed. Also wrapped the exhaust pipe up to the muffler

with  exhaust heat wrap.  The intake is not my problem for it is mounted low near the right rear tire in a compartment . The noise is

 tolerable now but must shut down to carryon a conversation!

      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

      So I've got a Hisun 550 that I was doing some work on that required removing the CVT and it's housing. Upon attempting to reinstall the clutch, sheaves, etc, I found that the belt no longer fits - it's far too wide. None of the parts have been replaced, they're all OEM. Exactly the same parts as what I took off a few weeks ago.
      To be more specific, my belt is 1.25in wide, but the gap between the clutch and the primary sheave is only 7/8in wide. I'll include a few photos to explain.
      Has anyone ever experienced such a bizarre problem? Any help at all would be appreciated, I've been stuck on this for a month. I'm open to just about any suggestion.

      Have a Hisun 750 only 700hrs 21 model. Never had issues went to start it and there's a clicking sound under the seat I'm assuming it's the started relay. I for the life of me cannot find the starter, is there a way to test the relay. 
      Thank for any support

      Going down a 20 deg hill engine is holding UTV back. Then something releases like going into Neutral and makes a loud clacking noise. Have to use brake to slow UTV down. Then once level it shifts back into gear. Have done shift extension does not pop out of gear.

      2020 Massimo Buck 400 - Won't start. Can hear the starter spinning, but motor never turns. Relay? Starter? Worked fine one day and not the next. Thanks for any help you can provide.
