My input on the procedure which I did for the first time last week on my
2001 ...
>>>> Never had to remove the sprocket cover or even the cams even though
both shims on the intake were replaced (exhaust was okay). Both cam caps
were removed and then the cam was "tilted" up on the right side. This
provided sufficient access to the shim.
When machining shims, be very careful that the finish matches the original
which is probably lapped to about a 6 micron finish. You can't get this
through simple milling or even grinding. To be safe, I would put the
machined side down.

Subject: [DSN_klr650] 1st valve adjustment
Completed 1st valve adjustment (for bike & me, too) on A15 with 1100
miles. (I know it was supposed to be done at 500 miles).
before shim after shim
int-r .005 280 .006 275
int-l .003 275 .005 270
exh-r .005 280 .008 272*
exh-l .006 270 .008 262*
Don't have a service manual yet, so only had Eldon Carl's adjustment
guide to go by (many thanks, couldn't have done it without it). The
cam chain sprocket cover must be new for the A15 since it isn't
mentioned to be removed and has to come off to remove the cam (Had
everything but the gas tank back on before I realized I missed
putting the sprocket cover back on, it was well hidden behind the
bench vice. Didn't help the re-assembly time). Also found it useful
to make an indicator mark the cam chain and sprocket with wax pencil
to insure re-alignment on reassembly. Was able to re-use 2 shims in
other positions. *Neither of the 2 local bike shops stock KLR shims,
so rather than wait for delivery, I carried the two 280 shims to
local machine shop and had them machined to 262 and 272,
respectively, for $10 and about 30 minutes time. Useful note is
going from 280 (or 2.80 mm) to 275 is a change of .002 inches (I'm
sure an obvious fact for most, but useful for a novice such as
myself). Glad I did it myself, will be much easier next time.
