So i have a 2018 Hisun Sector 750 Crew and while driving the noise level is outrageous.  I want to find a way to decrease the decibel level, so does anyone have any ideas!!! i was thinking about installing foam on the roof enclosure and possibly putting something around the engine bay area.  I have not found any companies that makes a suppressor for the muffler...Any help would be appreciated.  thank you

I have a diesel mule that has the intake in the rops bar. It's loud also. A back window tamed the noise to a tolerable level. Since I'm not familiar with your machine, it might not be helpful. But insulating, and deflecting that noisemaker away from the cab would be the way to approach this.

Just a shot in the dark here. But I see those black truck bedliners, on the side of the road that've blown out of a truck. That stuff would be an excellent material to fabricate what you've described.

I used this for good effect - self sticking with aluminum foil on exposed side.

      Hello, All!  I've decided to replace the traction batteries in my 2018 Sector E1 with a 48V Lithium set. They may be expensive, but I figure the Discovery Dry Cell are, too. I am not looking for the max driving range, as I have never received near the brochured range to begin with, but a good mix of charge/ get work done/ charge is what I am expecting.
      I have settled on the 48V EAGL kit from bigbattery dot com. Each battery pack provides 30Ah. The kit ships with a charger, as well. The packs would be physically connected in parallel (using a busbar) to one another, maintaining the 48V voltage, but together would be able to provide the amp draw the buggy pulls when going up hill or towing a rake (rated 320 max continuous Amps). This is in comparison to the serial connection the eight 6V lead batteries. Each of the EAGL batteries looks to have its own BMS; am I correct in thinking I will have to use their included charger rather than (simply) changing the onboard charger to lithium mode? The chemistry of the pack is LiFe PO4, for what it's worth.  I haven't torn anything apart yet (to diagram), so  I am not sure how the dash will interpret the AMP draw, but the kit I am looking at includes a dash mounted charge indicator.
      If anyone has completed a similar conversion, do you have any tips? Specifically, how did you remove the original batteries, and how did you secure the new ones? I am guessing that almost any change from the stock batteries would involve at least some modifications. Any tips would be appreciated, especially things I may have failed to consider. Thanks!

      Maybe members can post where they have obtained parts and service for their Hisun produced UTVs and ATVs, including the Coleman lines.  Maybe post the model you have, what you bought,  and how the products were quality wise.  Also if you had any shop service done, where (city & state) and how it worked out for you.

      I own a 2017 Challenger 750 and had the key way snap at the flywheel. It was removed and cleaned up and then the  flywheel was put back on with a new keyway. It snapped a second time so the flywheel and keyway both were replaced. They both seem to fit nice and tight. Put it all back together and it snapped again. I have no idea why it is doing this.

      My buddy has a ut400 that the forward gear keeps popping out of gear. She only has like 400 miles on the odometer .the shift cable has been adjusted and the shift lever has been updated / modified. All other gears are good. Is there an internal detent cam or something that wears out or shift fork that can be replaced ? Or is there some other magic that I can perform ? Looks like the engine needs to be split.

      When we first heard the noise, we immediately stopped driving it...at first we thought it might be a linkage issue, but after further inspection looks like the sound/jolting is coming from the rear diff. Took a video below...
      Anyone know what is creating the diff to skip/jump like this? We drained the diff oil and didn't look terrible, no metal.
      Other info that may be useful:
      1400 miles on it
      Recently tightened the E brake
      P.s. never posted on this forum before, let me know if the video does not work
