I spent a lot of today cursing whichever Yamaha designer thought it would be a good idea to put the FZ6-SA coolant expansion reservoir behind the downpipes and then cover it with a metal "shield" to protect it, so that was guaranteed to get corroded.
So what it meant was that one of the bolts that secures the cover was rusted and stuck, but because it attaches through a plastic bottle, you can't use a blow torch to free it up without melting the container!
This resulted in multiple repeated applications of Plusgas and WD40 trying to get the damn thing loose without bending the bracket or shearing the whole thing off.
Eventually I got it off, cleaned it up with a wire brush and painted on a load of Kurust before giving it a few coats of Hammerite.
At least on the S2 model they realised what a stupid piece of design this was and moved it up behind the engine, but that didn't help me
Still, the AIS is back on, the radiator is repainted and ready to be refitted, then I can put the coils back in place and get the airbox reinstalled.
Oh, and the header bolts loosened up nice and easily, so I cleaned them up and hopefully they'll come off as easily again if I never need to take the pipes off.
