I took my MT for a 50 mile ride last weekend. As the crushed rock roads were dusty I got out the electric pressure washer when I got home. Electric washer is not real high pressure and I was mindful of the radiator, but after parking in in the shed overnight, about half the water from the radiator was on the floor next morning. So the decision is whither to go with a repair or get an after market one. The local shop's tank test indicates a new core is needed and repair would be $300 to $400. A new aftermarket one can be on my doorstep for as little as $300, but most are in the same price range as the repair shop wants. Thoughts? Advice? Experience?
