Hello I'm looking into purchasing a base model kodiak 450 in the spring. Is there anything I need to know as far as problems with the kodiak 450? Any engine problems? Does it have the air box problem that the grizzly's had a few years ago where the air box didn't seal right and dirt would get in your engine? I'm coming off of a 2000 yamaha grizzly 600 and have loved it from day one!! Very durable and reliable machine! Can I expect the same reliability from the kodiak?
