GRiSO 1200SE
Left it sitting for 2 months in the garage and came back to find almost no pressure in the hydraulic clutch.
Just re-fill it and re-prime or is it a sign of something truly nefarious?
Fluid is a decent colour
Thanks

Bleed it and see what happens. How often do you usually change the fluid? If ‘Not very often’ the master cylinder seals may of collapsed.

Will do. Will report back. Fluid gets changed when it starts to discolour which seems to be every 2 years I'd say.

All the CARC bikes are murder on clutch fluid. No idea why. Every year or every 10,000km is our routine.

Yes, seems like that's the concensus. Mine always seems to be a decent colour and I've never had any issues before now, maybe I'll try harder and be sure to flush it once a year in future or maybe I'll just sulk about the extra maintenance for a bit first.
