I recently had my leaking rad checked out by a rad shop, they wanted way too much money to repair and recore it. So I called up Cruiserparts.net and bought what I was told was a very nice 60 rad for $150. I figured that was worth it, as the cheapest new I could find was about 275. I just tore into the used rad box, to find leaves and seeds stuffed in the tubes. I started flushing the rad with a garden hose into every inlet and outlet, backflowed etc. I got out a considerable amount of debris. My guess is a small critter made a nest in both tanks. I've flushed it out the best I could, but I obviously can't see inside. So, quesion is do I risk running it or not? Opinions needed. Oh, and this rad also has two male threaded ports on the bottom tank, what are these for? The old one didn't have these.
