Freddy, I've seen a Kawasaki KX250 run with .500" of play in the big end bearing! What a sound that made - you could hear the knocking echoing thru the shop. Made everyone come out of the front office to see WTF happened out there ... Takes quite a catastrophe to get them to NOT run - pretty amazing.
Yep that snowblower will put you out fast .... as in unconscious!
That 400 happen to be a Polaris Scrambler? Those are fun as hell - haven't ridden one in over 15 years. All 2-strokes are fun!
