djm137 replied to Jimbo45's topic in Sport ATVI heard from somewhere they are balls used to help balance the tires and wheels since we don't use wheel weights like we do on cars. Just a thought
Hey guys this is my first post, I just found the site. Usually over on z400 central or trx450r.org. Anyway I can tell you first hand that the K&N let some dust in my engine. I bought some cams to install and while the engine was open the mechanic noticed that my nikasil coating had a bubble in it and the piston was all scraped up. I had a K&N on there and they sent pictures to Suzuki and suzuki concluded that dust was getting in the engine. Granted I probably didnt clean and oil the filter as much as I could have but now I have a UNI filter. I had to get a whole new cylinder and piston, but worked out good for me becuase Suzuki covered the cylinder and I bought a hi comp piston. I have heard many posts on other forums about the K&N doing the same thing. It is a great filter in terms of flow, but the difference between that and a UNI for example is not worth a new cylinder and piston again to me.
