I have beaten the crap out of my two engines, summer hairscrambles (12) races, practices, winter snow racing, studded ice racing, hauling the kids on our camp site, 2 years and not showing a hint of fatigue. I have everything stacked up for replacement but it just won't give !! 20 hours for me is just broken in.
That stands for 3 rings pistons, but if you happen to have a 2 ring piston, they are good for 20 hours, they are easy to spot, the engine puke oil trough all the seals lol
