Well.. never felt a bike should have a radiator.
Found a use for em tho. I bought one off ebay for some kinda big honda I think.. mounted it in front of my main radiator in my chevy powered Healey and ran heater hoses to it.
Figure it't taking about a hunnert HP load off the main radiator so that the main only has to cool around 300 hp now. Healey's are a bear to cool but if some of you have Hot Rods that are similar with cooling problems....
