I agree, but, I also have replaced all my half rings (broken) every time. So I try to get closer to .000 to account for the break-in of the new ones. If I were ++$$$ I would go the MBP colet route, but that's neither here nor there. I may go that route whenever it is valve guide / engine re-paint time.

At my first adjustment at 7500 on my 1100 evo, I replaced the half rings with MBP. In nearly 50000 miles on my s2r, I never had an issue with them.

To give you an idea, I ran 10000 on my adjustment. So from 7500 to 18500. The closers did change a little (. 002" to .004 on the exhaust and only. 001ish beyond spec on the intakes.

I expect the bike was still breaking in. I wouldnt be surprised if this allows me to go fully to 12k for adjustments on the next iteration (in sync with a belt change). Less downtime means more fun.
