I have a 583 out of a 94 formula Z. It is a complete engine, the problem is that it was damaged where the recoil and flywheel is. That shroud was cracked and now the recoil doesn't fit. So if anybody needs a parts engine this one would be great. I have everything for it including the carbs and pipe. If anybody needs some parts or wants the whole things make me an offer. I have no use for this engine anymore so hopefully somebody else will.
