Open heart surgery - Haugen - 14-06-12
Oh woe...
About three or four weeks ago my FZ1S gen2 dropped about 100 milliliter of coolant when I arrived at work. I called my mechanic who told me to keep a close eye on the level of coolant in the expansion reservoir. I did and all though the level fell a bit it wasn't much but it seemed that the colour changed to slightly brownish. Since I was planning to go to the Netherlands this week so I thought I'd better have a look at it just to be sure. I dipped a q-tip in the coolant and it came up blue. I had a look at the back of the oil filler cap, no mayonaise.
I'm not all that well versed in things mechanical so I went to see my mechanic. He told me to go for a ride and then keep an eye on the bottom of the engine. Apparently there is a hole which will leak coolant in case the ceramic gasket (Right term?) in the water pump had ruptured. I looked and there was a drop of coolant right where it shouldn't be.
I talked to my mechanic the next day. The verdict was open heart surgery... He will have to change the ceramic gasket, a 5-hour job, and not cheap either.
Have anyone else had this? I haven't read of it anywhere.

Hi there.
Yes, not a totally unknown failure although rare, thankfully. You are one of the unlucky ones.
Read all about it - with loads of photos - here: http://www.yamahafz1oa.com/forum/showthread.php?t=37957&highlight=water+pump
You can continue to ride with the mechanical seal weeping like that - that's why the drain hole is there - but it's something that is better fixed sooner rather than later.
