Hey guys, I spend most of my time on the yz450f side, so please excuse my ignorance. My riding buddy has replaced the valves in his Honda for the last time, and now wants to get a YZ250 (or possibly a KX). So I told him I would 'ask the pros' if there was anything to watch out for. He wants a new bike, probably 07or08. So please let me know if they have any inherent problems(i.e. trannys, pistons, suspension failures, or anything else he should be cautious of), or are they as bullitproof as the 450f's. He is remembering the 'good ole' 2 stroke days when he rode a YZ, and got to ride it more than he worked on it, unlike his present situation.
