I have a 04 fz6 40k on clock, notice coolant levels drop after riding. At first I thought it was just the overflow tank coolant levels fluctuating due to usage warming up and cooling down engine. Until the coolant levels remained low, causing me to have to keep refilling it. I never let it drop below min mark before refilling it to max. I would say I have to refill every 2 full tanks of gas depending on how hard I'm riding it, so I'm slowly losing coolant (6oz of coolant if I had to guess). I did a coolant flush using engine ice about a month ago and removed radiator cap with engine running to remove any air bubbles and also to make sure it was not boiling over which is a sign of blown head gasket. Also, far as white smoke another sign of head gasket leak, there's is no clearly noticeable or obvious white smoke but it is starting to get cold out so slightly harder to indicate. Bike running strong, radiator cap looks healthy but still considering changing due to bikes age, no coolant drips on ground, although I could be possibly over looking a small leak around overflow tank due to tight space. just don't know where my coolant is going, any suggestions?
