one of my buddies is selling his 400ex the only bad part is it leaks oil really bad and he doesebt know where it is coming from but he is selling it olfor 600 do yall think it is a good deal
BD7 by a hair.
@OP, what's the rest of the quad like? Could be base gasket, head gasket, valve cover gasket, seal leaking oil. Or as stated busted case. Look it over close, might be a deal or a clunker. Lotta work and money if it's a busted case X(
well i think he base gasket is the problem and i know it needs rings because it blue smokes
