Well, like the title says I just joined and bought a 400ex recently. It's completely stock except for a UNI filter. I've ridden 4-wheelers all my life, but never got the chance to own one. I'm wondering if there's any "common" knowns about the quad that people could fill me in on? The previous owner just changed the oil with Honda brand from the dealership. I was thinking of running Redline (as I run it in a few of my other toys) but i've had people tell me the Honda brand is fine. Any advice is welcome, thank you!
