Hi- recently experienced what appears to be an engine coolant loss, about 300 ml over 1000 miles of riding; no "fudge" in the crankcase oil or in oil sight glass (so im hoping this is not a seal/head gasket breach), no puddles, leaks, drips or staining that I can find (looked all over bike, garage floor, and fairing areas.) Bike running temp unchanged, and bike runs well. its a 2002 w/ about 15k miles, and the coolant is new this year (I changed/flushed the coolant in May @7000 miles). I had recently (prior to the 1000 miles of riding) added coolant when the bike was on its center stand, cold, to bring resevoir from min. line up to max line, and now its back to min. line again. Any ideas? thanks in advance.
