Hello everyone! My name is Jim Schupp and I live in Indiana. I purchased a 1998 grizzly 600 this year and looking for a place to discuss issues with like minded yamaha fans. My griz has problems and I am looking for advice and help to get my mean machine running top notch. I am looking forward to reading/making posts. I will read already made posts to find my answers, but will be asking questions too. This is my first quad and I am proud to have it, despite the knocking noise going on.
