I am building a cr500af. The engine is from a 93 and I have a chassis from a 99 cr250. I need to know which radiators I can use to hook up to the 500 engine. Right now the radiator I have for the 250 doesn't hook up because it only has 2 hoses that go into the engine. I need some radiators that have 3 hoses. Two for the cylinder head and 1 for the water pump. Also the radiator on the 250 frame is 1 square radiator that sits horizontal. Can I mount normal radiators on this frame?
