____ Perhaps being too-late for Doug now, I then of-course certainly regret submitting my-own response-post at this untimely point,, but the actual fault for the delay was beyond my-own control, as I had (once again) lost internet-access (for about 76-hours, this time) due-to a BAD-weather related occurrence which had happened nearly 2.5-hours before Doug posted this thread !
__ Anyhow, I'll
now rather springboard off-from Jordan's response-post.......

" You need to pull out the rocker spindles to remove and change shims. "
____ That valve-shim replacement-method is certainly true, but only for DESMO-heads !
There's really no need to go to all that extra troublesome effort for simply changing the shim-caps in
springer-heads...
All that normally needs to be done in order to drop the valve & shim-cap down & away from the rocker-arm far enough to create sufficient clearance so as to then be able to simply lift-out the cap (from between the valve-stem & rocker-tip),, is to use a fairly long screwdriver (which has a
square-shank - [and
not a std.type round-shaft] ),
by placing it's tip-end
fully-underneath the ledge that's located directly under the rocker-spindle, and with the flat-side of it's square-shank flatly resting against the spring-tie -(# 160), then press the screwdriver-handle downward until you create the required space-gap (to fit the cap through).
For rather rare instances where the valve, keepers, & spring-tie aren't all inclined to stay rather stuck together,, then in the (sometimes possible) event that the spring-tie tilts & compresses either valve-spring considerably unevenly, then simply rather try levering the spring-tie downward on the
other-side of the valve & cap.
__ And in the
extra RARE-event that the same excessively uneven spring-compression still occurs also on the
other-side as well,, then ya could rather use a pair of screw-drivers, (one on
each side), so as to then better control more evenly level spring-compressing.
And if this (USUALLY
unnecessary !) method is used, THEN it doesn't matter so much as to what the particular shape of the shank/shafts are (of the chosen pair of screwdrivers).
And also,, if ya happen to have large-boned fingers, then you'll possibly require needle-nose pliers to grab the shim-cap out from between the screwdriver-shafts.
