.003 Closer shims

7500 miles and I just got my valve clearances measured. 3 openers are in spec, 1 is .005 and will get replaced. My problem is that all three of my closer shims I measured, and remeasured, are at .003. Here is my question:

I've heard that new half rings will add +.001 to the clearance. Should I try and replace just half rings and ride with .002, replace all 4 shims and NOT the half rings (anticipating the new ones will "break in" and increase the clearance again), or replace all 4 shims and half rings.

I don't constantly hit the rev limiter and ride this bike around town for 75% of the mileage. Perfect tolerance is less of a concern here but I want to do things right, not looking to save a dollar. I just think the half rings are suspect when my openers are generally in tolerance and my closers are generally out of tolerance by the exact same amount...

Any knowledge/experience is helpful

Get it exactly right, and to the old specs, not the new ones. Also, when I did mine, I did not experience the new half rings changing things a full .001.

Slightly off topic.I find the springs on my 1100 a LOT harder to compress when working on the closers.Is anyone using a tool of some kind to compress the rocker? And i don't mean the silly thing that looks like a nut driver.I use that to do the shims on my 944.It's easy to change them.
