I have an 08 grizzly with clutch kit is all. I have found when comparing it to others that mine sounds a bit noisier, not running ruff or anything like that, it idles good and runs good just seems to have more of a rattle coming from the engine and just a plain ruff sound (It is Noisy). I was hoping it was in the clutch but pulled it a part and seems to be good. Is it possible that the valves need set after only 700km? Any good knowledge appreciated. Thanks
