GS1000 Master Cylinder Rebuild kit

[Duncan]

Humm. I might go and look at the 47810 parts again, but if the plunger is in a different position to the original it’s not going to cover/uncover the aperture to the reservoir in the right way – It could always be blocked, or the piston end may never pass the aperture and fluid is forced up into the reservoir rather than down to the callipers etc.

I’m going to mull it over, but I can see I might have to start a new thread along the lines of ‘What’s the cheapest replacement for a GS1000 master cylinder?’
