I recently purchased a 2020 Massimo 400 EFI and began installing soundproofing to lower the overall body noise. The model I choose is the crew cab with rear facing seat and diamond plate bed.
the first phase involved removing the rear deck and applying Noico 80 mil sound deadening mat over the exposed diamond plate sections of the underside. This immediately removed the sound of vibrating metal plate!
Next phase is to continue this application to the interior of the plastic around the engine compartment and then any other plastic panel that has a "hollow" sound. It will add 2-3 pounds to the overall vehicle weight but it makes a huge difference in noise reduction. One question I have - there is a vent directly in front of the engine (behind a drivers leg about calf level) I am strongly thinking about covering this as the level of engine noise here is huge. The engine is water cooled so I don't think this is a problem as the air input is minimal - but i don't wish to overheat the engine.

Bought new in 2014 Renegade 1100. Life got in the way and only put 80 miles on it up till now. During that 5 year time the fuel would go bad and I would drain the tank and refill. Always used 100% gas [never ethanol]. It is garage kept and never spent a night outside.
Now that I have time to use it, I am having issues. It will start and run fine for about 10 minutes, and then it will start to miss and then eventually die. After letting it sit for about 30 minutes is will start back up, and start doing the same thing again.
I have put new plugs in it and have replaced the fuel filter.
Any suggestions on what this problem could be?
Thanks in advance for your help,
Hi, I just purchased a Massimo MU500 that we are going to use in the North Georgia mountains.
After the first couple of test drives it seems a) somewhat underpowered and loud as hell.
So wondering if I switched out the mud tires with something with smaller tread if that would maybe help?
Also I found a muffler replacement called the “silent rider atv silencer” and wonder if that would help with the noise without killing power.
