i've read about a similar post about the stock grease. a handful of members said that this is the best grease out there and not to strip it off. they suggested to wipe excess with a clean rag and ride. apply your lube when necessary.
a few had experiences after stripping it off saying it sounded better with the stock on and lasted longer.
