valve shims

I just checked my valves both intakes at .004 both exhaust at .006, tight
side of scale .
Should I change to next size smaller or wait a couple K to change them. As
next size down would give me .006 and .008 middle of range.
Thanks

I was thinking about one of my project bikes the other day (76 Z900) particularly about the fact that the valve shims from my A12 are identical. I know from second hand experience that the old Kawis could spit a shim at high rpm and destroy lots of good stuff, thus the move to 'shim-under' buckets.
I often ride my KLR up to redline but now I wonder if I risk spitting a shim. I am not aware of a rev limiter on the KLR (I have yet to reach its limit if it has one). Any thoughts out there on a sunny Friday?

so in preparation for moab, and with 6300 miles on my y2k, and with the
knowledge that one of my valves was right at the spec limit when i checked 2
months ago, i set about tearing my bike apart. much easier the second time,
at least as far as the valve checking goes. it only took me a minute or so
to get the valve cover out this time. it seems to help if i pull the rubber
gasket out of 1 side to clear the cam chain guide and stuff a little easier.
2 more valves had closed up 1 feeler size (.001), i think they were at 004,
005, (in) and 006, 007 (out). i figured i'd drop 2 sizes on all but the 005
and 007, to put them at the far end of spec, so i wouldn't have to muck with
them again for a long time. called the local kawi dealer, who usually has
good prices, and he wanted $9 each. WTF? i knew fred had em for way less,
and i know fred is a fairly small operation that gets fairly standard retail
margins, so i figured there had to be a better source. called the local
independent parts shop, they want $5, or $2.50 with trade-in. much better.
went in and got them (got a tire too, and some spare tubes) and discovered
they were yamaha shims. so that's the ticket. anyway, they look the same, so
no problem. got home, put them in, checked clearances. i had expected
clearances of 008, 007, 010 and 009, but instead i got 007, 007, 009 and
009.
so i was curious, do most people find that the new clearance is not quite
what they calculated? mine are pretty dang close, and they're exactly where
i would want them if i could choose, but i was wondering if anyone else had
noticed such a thing. maybe the new shims seat in microscopically after a
bit. maybe i had too much oil on them when i put them in. maybe yamaha shims
are ever so slightly different. maybe shim manufacturing tolerances account
for it. maybe i was measuring in inches and the shims are measured in mm. i
dunno. just curious anyway.

My local Kaw dealer parts dept. wanted $12/shim. I talked with the
guy who ran service, who BTW owns a KLR, afterwards. He told me to
come to the "back" door (service dept), and swapped them even - no
charge.
You might try to talk with the service guys.

Seems I remember reading a post where someone had purchased some sort
of valve shim package. Is there such a thing available? I'm getting
ready to do a long overdue valve check myself and would like to save
myself the time of waiting for the nearest dealership to order the
shims.

A lot of us have had luck trading shims at the local dealer. I think Kurt
has a shim bank available to those who can't trade with the dealer. I could
be wrong but at about $15 USD each, a package that would give a variety of
shim sizes would be a bit expensive. IMHO

Most good dealers will swap shims for free, but I bought about a
dozen from Fred for the convenience of having zero down time. The
problem is, after doing valve adjustments on my two bikes and for a
couple of friends, I'm left with a big pile of 260's and 270's! I
now have to go swap some with a local dealer to restore my size
assortment.

yep, kurt generously (how else, knowing kurt?) donated to me the remnants of
the "shim bank". he ran into lots of problems managing it previously, but
if there seems to be a big demand (i.e. lots of people who's local dealers
won't exchange shims, like mine), i might be willing to give it a shot.
