2nd valve inspection 650R

07 650R
2nd Valve inspection @43+mls, 1st done @15.5Kmls
I'm in process of the valve inspection, and dont know what shims are in place. The service manual lists the Exhuast clearance @ .22-.31mm, and the intake clearance @ .15-.21mm. I'm just barely @spec w/ intake@.155mm and exhaust @.225mm. My question is: Should I try to find smaller shims to bring clearances closer to a middle spec setting or looser measure than present? This present measure is what I set on the 1st valve inspection @15.5k mls. Hasn'nt changed since then. Wouldn't be hard while open, but are shims made? According to manual chart, only much larger or smaller is made. Also since open @ this mileage, any other inspection or service should be done? Already replacing plugs and cleaning air filter.                                                                            Please Reply,

You'd have to pull the cams to see what shims are under the buckets.  You could then swap them out if you want to set them back to the middle of spec.  Your local shop may swap out sizes you need or charge a few bucks.  They will only get tighter if they move so you may as well bring them back to the middle since you're already in there.

If it were my bike, I would take the time to get it back to the middle of the spec.

What I did. I found the dealers shims to be off spec enough to measure and record each shim and install accordingly, and  also synced throttle bodies.
