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.

      Snow Blade for Coleman Outfitter 550?
      By Alien10
      I'm thinking of buying a snow blade for my Coleman Outfitter 550 (Hisun with Coleman stickers).
      Has anyone purchased a snow blade that can offer the make and model they bought and any comments, pros  cons etc.?
      Not 100% sure I'm going to buy, as the selection of blades for this model seems a bit thin on line. 
      Thoughts and comments welcomed.
      Thanks in advance.

      Coleman UT 400 replacement decals graphics?
      By Homeowner A
      Have a bed decal that has never been right.  Contacted Coleman Powersports and they have no solution.  Anyone know of a place where I could get a replacement decal or complete decal or graphics kit?

      Coleman UT400 - 6v or 12v battery?
      By Rainman
      I want to put a charger/maintainer for my Coleman UT400 for the winter and need to know if it uses a 6v or 12v battery.
      One search online showed a 6v, but another stated 12v..
      I can look at the battery, but after taking the seat out you cannot see the top of the battery without also removing the top plate under the seat and at 8 degrees outside, I'd rather not be out there too long.
      Can anyone verify what volt (6 or 12) the batter is?
      Thanks in advance ...

      Kioti K9 too loud!
      By LeMay624
      Hey guys! Was wondering if anybody has had any experience in shutting up a Kioti K9 or Kioti Mechron.  I daily drive a K9 in an underground mine and between the engine noise and belt whine I can’t hear myself think while driving this thing! 2-5 hours a day. It’s a 2021 model with 180 hours on it. Belt and clutches are clean, machine is maintained to factory recommended schedule and then some. Has been like this since new. Before I start boxing in the engine with plywood and stuffing insulation under the seat I thought I would reach out and see if anybody has run into this before!
