Need advice from the brain trust. I purchased a 2004 200EXC that has been sitting a long time. It was last ridden in 2007. Cleaned carb and fuel system and figured I would warm it up and change fluids. It ran great and proceeded to overheat. Coolant was close to full however when I removed the cap I found what look like salt or mineral deposits around the filler neck. I decided to redo the cooling system and ordered two new radiators from Mylers. I was not sure about the cheap radiators found on ebay. Next question is where can I find a quality silicon hose kit for this? I find some cheap ones on ebay but they say sent from China may take weeks. Samco and most of the online shops do not list them for this year range. Last question is the silicon hoses seem to bypass the thermostat. Is this a good idea for trail riding? It would seem like the additional warm up time might not be a good idea on a 2 stroke. Thanks again all help appreciated.
