Have just pulled my clutch slave cylinder off to rebuild and felt up where the push-rod comes out of the clutch housing and it feels like there is a seal there which seems like its gone really soft and spongy....is this caused by the brake fluid leaking into that area and damaging this seal.
i have a rebuild kit for both the master and slave cylinder due to losing fluid.
My question is should i replace this seal as well and how hard is it to do with the engine still in the bike.

any thoughts on this would be greatly appreciated.
