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.
