Hi, hopefully someone can help. I usually run the bike every week until fan comes on throughout winter. Did the same today. Usual thing, revs go up to just over 2k and then slowly comes down to normal as temp bars rise to 3. Then let it run until fan came on. Just about to turn it off when I noticed coolant pouring out from under bike. Immediately turned off and as I did so noted that temp bar was right over to right side. Once turned off I could hear boiling noise for several minutes. Checked on here and having left the bike to cool I have stripped the plastic off but cannot find any sign of where the coolant has come from. The hoses under the air box look in good order and secure. Same with all the hoses from the radiator. I was unable to detect a split hose. On taking radiator cap off I found coolant topped to brim but no sign of overflow. The overflow reservoir looks in good order with no damage. It was at low mark, but may have been for some time possibly. I dare not start the bike up again in case I do damage. In fact will there be damage due to boiling noise? Any advice on what I should do will be greatly appreciated. The bike is 08 in excellent condition. Many thanks.
