I put my bike away for the winter back in late October and everything was fine. The bike sits in neutral on a rear stand. Today I squeezed the clutch lever (bike was off) and there was absolutely no clutch lever pressure. The lever just went all the way in with zero resistance. I suppose I can try putting it in gear when the bike is on to see what happens, but thought I'd ask first if this is likely to be a clutch slave cylinder leak issue? Something else?
