Coolant leak

[Ollieclarkx64]

Hi, I bought a fzs600 for cheap planning on repairing it and have only recently actually been driving it on the road after having it for a year. I’ve attached some photos but sometimes after a long drive I notice coolant leaking from where the top end mates with the rest of the engine. There’s no white smoke coming from the exhaust and really no other symptoms but I’ve been thinking the headgasket could be failing? I would love to hear some of your opinions and advice hoping this could be an easy fix.

It does look like a head gasket issue. Check the oil filler cap for mayonnaise and do a sniff test on the coolant expansion tank.

It would be unusual to have a head gasket coolant leak on the 600, it is most likely from the pipes at the back of the cylinder head. Corrosion can damaged the O ring seat and deform the seal and coolant will like down like you show in the picture. The pipes are just the base of the cylinder head one left and one right.

I can’t always see coolant leaking but I had another look last night after a ride and it does look like it’s trailing down from somewhere higher up and I’ve never been so happy to see a leak before but I’ll inspect those pipes as soon as I get some free time. Looking at some diagrams it looks like there’s a single bolt holding the pipe in place is it as simple as taking the bolt out and sliding out the pipe after draining the coolant or is there something else I’m missing?
