Have never owned one or knew anyone who has one. I've ridden all my life and have 2 700 Raptors and a Yxz sitting in the shop. Am looking at buying this for my grandson. Am selling his Z250 and wanting to get him a 450 with efi, the z250 will be the last carb quad I ever own. Have found a nice clean 08 with a K&N and full exhaust. Just wondering if these are reliable quads, not looking to get into something that needs constant attention. I used to race KX motorcycles and have owned a few Tecate 3 wheelers, have always been a Kawi fan. So are these a good reliable quad? Any know problems or things I should pay attention to when I go to purchase?
