These Coleman 400's are LOUD, so loud I wear earplugs when cruising. With that in mind,I added a secondary Kolpin silencer to the stock muffler. It helped a bit but the thing that has helped the most is foam sound deadener. I added the foam deadener to the inside of the plastic front seat base,covering the whole surface. I also added a piece on the driver side plastic cover and the side of the gas tank facing the motor. I used standard acoustic foam known as eggcrate and contact cemented it in place. Very noticeable reduction in the noise from the engine and drivetrain. Much more enjoyable ride for just a few bucks.

      Considering buying a 2021 1500 coleman
      By Rusmis91
      I’ve never been around Coleman Utv machines. Do they have a good reputation, durable dependability. Could you compare them to yamaha rhinos or Polaris ranger
       
      thanks in advance

      Coleman UT400 rear shock height adjustment
      By mrpro
      I got the fronts adjusted.  I'm trying to raise the ride height in the rear, but my spanner wrench keeps slipping.  Is there an easier better way?  It's like there's too much pressure working against me to be able to twist the height adjusters.  How can I relieve that tension to make them easier to turn?

      Is Your HISUN Loud?
      By HISUN Sector 750 EPS Failu
      "Mrs. Smith" doesn't like how loud our Sector 750 is.  On a HISUN forum someone said the same thing about his 750.  I haven't given it much thought because I've been more focused on stuff that has broken.
      So, I used my decibel meter to check ours out.  4000 RPM, Low gear, under 20 MPH . . . . 97 decibels.  That's above most ordinances, even state boat noise limits.
      AI Overview Ninety-seven (97) decibels is considered very loud and dangerous to hearing with prolonged exposure, roughly equivalent to a newspaper press, a loud nightclub, or a snowmobile. At this level, damage can occur after just 30 minutes, necessitating hearing protection

      Hoping someone out there somewhere can help.....2019 Massimo Buck 400S
      By AaronD1982
      Onto the next problem, everything has been replaced in the charging system except the Flywheel Rotor, I have it torn apart all the way down to said rotor, but it is suggested that a specific puller is required, and a compatible rotor seems virtually impossible to find.  I can find many like it, but this one is mine scenario for those that get the reference.  For all I know I have the last Massimo Buck 400S on the planet and will never find another part again, but who knows.  Any ideas, help or otherwise that anyone might have would be greatly appreciated.

      Silent Rider Silencer Update
      By HighSon
      So for those of you who have dabbled in muffling your insanely loud Hisun, I just wanted to give an update on the Silent Rider Silencer project I reported on just short of 3 years ago. The silencer has failed from rust rot. So in the end, not a good investment. If I do a different one, pretty sure it will be stainless this time. 
      If others have tried other add-on mufflers or fixes beyond what’s already been reported, please post your experience.
