I need a complete motor for a 2004 400 yamaha kodiak 4 wheel drive. Big bear motor will work, I think. Atv is in such good shape, hate to just part it out, but not worth 1600 bucks for rebuilt motor. Also, guy working on it says a customers e-bay motor he bought probably has to come apart for further work, so he doesn't trust that route. Probably has to less than a thousand bucks to come out on it. Thanks.
