These clowns block the highway for a wheelie contest.

But, when you get to 4 stroke mx bikes, piston changes and the like are on a 12-15 hour schedule. Essentially, you're supposed to change out major engine components more often than you're supposed to change the oil on a street bike.

The racebikes, that I'm talking about, were 125 and 250 GP bikes running premix. You do a top-end on a GP bike roughly every 300 track miles, unless you notice that there's an issue before then. The tires last longer than that.
