Novarossi has a history of lasting long as well as RB (very similar engines most rb are nova based) O.S has a bad record of not lasting as well as Werks.
BUT engine life and performance also depends hugely on care you can take an amazing engine break it in poorly don't tune it well overheat it don't maintain it suck some dirt in there and all of a sudden.. your engine craps on you at 3 gallons. Were if you break it in properly tune it well maintain it and treat it good it will last for 8-9 gallons.

my 2cents.
