Performance isn't cheap, anyway you look at it!

Well, either way I was going to rebuild the engine no matter wich one I picked up so I am not to worried about that. I am not shure if water actualy got down there or just moisture from sitting so long. It has the air cleaner on and everything and even covered with a tarp. It has just sitting out behind a barn for a number of years. It ran when he cut the frame its just that it was to rusty to save. Also, it was rebuild before the guy got it so with the frame being rusty and all I am not shure how many km where put on it. I was thinking you could save the pistons if it wasnt to bad. just go with new rings, seals and bearings all around. Then just put a new cross hatch on.
