so on a supermoto bike piston every hour or so and crank/lower end rebuild when?
I'm curious about this too. My bike ('11 YZF450) runs supermoto about 20% of the time and MX the other 80%. Just curious when I should be looking at doing a top end in it to prevent a catastrophe. I waited too long on my Husky 250 and it dropped a valve.
