I went at it for about 20 minutes with a hose and mud was coming out like crazy, but i thought i cleaned it well. I changed my coolant also, well i drained the plug on the radiator which isnt ALL the coolant and i WILL be adding some water wetter before i go through the relocation. I just got a Clymer manual and will drain all the coolant out and add water wetter and see what happens. I dont think the coolant is bad, the bike has 58 hours and hasnt been ridden in ~2 years!
