Did you connect some disconnected lines under your hood? Sounds like your LSV connection. That is the LSV feature (low speed vehicle), for indoor use, training, youth, etc. Keep it unplugged for full speed. See picture. Red box on the LEFT.

Hey Mac66, Check out what I did to address that issue. Made a MAJOR difference. On most UTV's the noise is from the intake. No so much on the muffler. I had the same issues you described.

That looks aggressive! Ready to tear it up if needed.

Oh yea...looks good!

You can buy a dashcam at amazon under $50 and get some great trail riding footage. That's what I use.

Post some pics if you have'em! Like to see'em I will probably upgrade to 29" just for the fun of it. I'll let you know if I do. And see how it works out.

Hi Kalyla, I have a brand new BOSS BRT17SLR in the UNOPENED factory box. I will sell for $160.00 ($150 unit, 10 shipping) Good unit! I've owned one before. https://bossaudio.com/products/791489132046?variant=48798040129696&currency=USD&utm_medium=product_sync&utm_source=google&utm_content=sag_organic&utm_campaign=sag_organic&tw_source=google&tw_adid=&tw_campaign=20742584627&gad_source=1&gclid=EAIaIQobChMI7cXdsPH9hAMVNTfUAR1xfANdEAQYASABEgJzU_D_BwE I ended up going with the BOSS BRRF46A. It ROCKS! You can see it in my profile. -----Blair

My 2021 Massimo MSU 800 has never been on a trail. I live in Nashville and it's just a fun vehicle to cruise around all spring, summer and fall. Winter, it stays in the garage and gets cool upgrades. It's a just a cool hobby machine. I even drive it on the interstate sometimes. (cops in Nashville don't mess w you) It will cruise at 70MPH with the larger 29" street tires I put on it. It has almost 3000 miles with not a problem whatsoever. You will want to get some street tires. Those off road tires are NOT designed to travel at high speeds, they will sling apart if they get too hot. Plus street tires are SO much quieter. People stop me and take selfies/pictures all the time. The girls LOVE it and I love the girls. I named it TAZ and it has the Warner Brothers Tasmanian Devil decals/theme going on. Yep, it's just a FUN machine with a bumpin' stereo and the best underglow lighting. You'll see several of them cruising around in Nashville. Hope that helps Brother. I have identified life as a time to LIVE!

My Hisun came with 14" wheels and 26" tires. I upgraded up to TPI 15" wheels and 27" tires. Wider tires rear tires than the front. Runs and operates great. I'll be putting on even bigger tires this coming spring. You can see them on this link below.

Most of us complain about the ridiculous noise in the cabin. My wife likes to ride but the noise is a major downer. You can’t even have a conversation without shouting at each other. Well, I manage to reduce the cabin noise by approx 200%! I addressed the intake that is poorly placed right between the driver and passenger. First, I cut the air filter inlet pipe in half (pic 1). I then reinstalled it upside down (pic 2). I then attached a flexible intake tube (pic 3) and directed it behind the cabin (pic 4). Major difference. Then I covered the interior engine cover with Dynamat extreme and then 200 mil Chaogang sound deadener / heat shield mat on top of that (pic 5). Since I cut off the intake and redirected it, I completely closed off the intake (engine fence) so no engine noise can come thru (pic 6). It also reduced the heat approx 50%. I did leave on the heat mat that came stock on the engine cover, so it has 3 different mats. It was a snug fit. Major difference again. My wife rides all the time now since we can have a conversation when we ride. Major improvement to my riding experience. Thought you might like to check it out.

Did you plug in anything under the hood?

Just finishing up my street legal project. What do you all think? I'll be listing it this week.

Think I'll try it over spring/summer. I'll let you know if it has a negative effect. Thanks

Did you cover the vent? I want to do the same thing. How did that work out? Did it overheat? Thanks Blair

Yea, I kinda stalled out over here. It's been raining and turned a little too cool outside. Here is a adjustment point. The tiny red X is the nut I will be tightening. It's too cramped in my garage right now to do it. It was a challenge to get the picture. What do ya'll think?

When I see that weird name, I just look at it. I've never even tried to pronounce it. I didn't see any benefit from it.
