So I have been saving for an '06 SE 450 but i just went to Corral Canyon last weekend and really enjoyed it there. The bad news is they don't allow red stickered bikes (with the exception of DEC and JAN but I don't like to ride in mud or snow). I currently have a '97 CR250 and really want to switch over to a yzf but would also really prefer a green sticker. I know a WR is more suited to that type of riding but I spend a fair amount of time at Elsinore and would prefer sticking to a true motocross bike. If I understand correctly the '03 yzf450 is the last green sticker YZ. If so, is there anything I should watch out for if I decide to buy one used? Since I have other money sucking hobbies I can't justify two bikes to the wife-she lets me get away with a lot but I know where to draw the line... Any input would be great, thanks.
