The forks were noticeably more plush.
after you had just done a strip down and clean? whodathunkit....
or did you mean they felt plusher than the last time you had freshly stripped and cleaned them?
How old are the forks, could they have bedded in a bit more,a dnt hen the clean and lube jsut made them nice and fresh again?
A little bit more Oil in the lowers will keep them lubed for longer and do no harm, but unlikely to make them feel noticeably plusher. Oil levels in other parts can be quite sensitive and you didn't mention whether you were talking about oil in the lowers or in the spring and damper assemblies.
