If you own a Beta and have any decent number of hours on it, please make sure you at least check your oil pump gears? Ideally change/replace them with new ones.
Here's the middle gear that has just come out of BluLu's 2013 Beta 498RR - less than a third of the gear teeth contact areas still making contact. I shudder to think how close this gear was to failing and resulting in a seized engine!
IMO the metal gears are the way to go for peace of mind.
