I noticed that my TRX300 makes a slight engine noise…hard to explain. It kind of reminds me of a cross between a supercharger whine and a vacuum/air sucking sound. The noise isn’t loud…I’m thinking the 02 Rancher I bought new made the same noise. I’ve looked all over the Internet for one that makes the same sound and the only one that I found was a video that a guy made of a mint condition TRX300 4×4 in which he was just making a video of the cherry he bought. Just wanted to make sure that it was normal and that it doesn’t need serviced. It starts, idles, and runs fine.
