My husband has a 2005 new-to-him 1800R and it has a radiator leak. He just put on Cobra Fatty bars last night and no trouble before this. He thought he had a loose hose because there was a coolant leak dripping from the hose location. Tightened the hose clamp last night. The drip appeared to stop. This morning, started the bike and let it warm up, and noticed a small puddle of coolant underneath the hose. Took the car to work. Tonight he loosened the clamp, reseated the clamp and tightened it again. Started the bike, still getting the leak. Took the left and right hand covers off the radiator and removed the lower cover, dried up everything with a rag, started the bike to see where the leak was coming from. It appears the leak is coming from right side bracket that's soldered onto the bottom of the radiator. It's a slow leak but he is concerned nonetheless. Can the radiator be repaired? Is it brass/copper or aluminum for the tanks? Sugggestions?
