Well, I arrive home and notice a small pool of coolant under my stored 2005 RC51. I cleaned up the mess, took off the left fairing, and had a look around. It seemed like the coolant came from a hose near the reservoir, but l couldn't see too much with a flash light. So, the weather was about minus 40 degrees CELSIUS in December and the start of January, then warmed up to plus 6 celsius the past week. The engine block, etc wouldn't have cracked I would imagine, and the hoses look ok. Would this be a matter of a 50/50 mixture (regular coolant) and a deep freeze then thaw? Has anyone encountered this before?
