I don't log hours, but I have 2 seasons (icluding ice racing) on the last set. A few Silver Lake rides, mostly short motos, but always at maximum throttle.
My post was more to Steve's assertation that a looser bore will lead to needing to go to the next size piston sooner than a tight set up. I realize that is affected by the number of hours on an engine, as well. The rings weren't always worn out, just changed as long as it was apart. The amount of hours on this size piston has been as long as any bore in my Pilot history, where , when I set them up tight, the damage caused sticking the piston required going to the next larger bore right away.
Lee, I have never done what you describe. If you set them up tight, that might be a good idea.
