valve clearance history - redux

[Spike55]

I'm shooting for 0.150-0.250mm on the exhausts and 0.100-0.200mm on the intakes. Again, this is on a 2006 KLR I've own from new. First clearance check was July 2, 2007 @ 5,047 miles: old-L-Ex 255mm shim w/ 0.178mm clearance - SAE feeler gauge new-L-Ex 250mm shim w/ 0.228mm clearance - not actually measured old-R-Ex 255mm shim w/ 0.178mm clearance - SAE feeler gauge new-R-Ex 250mm shim w/ 0.228mm clearance - not actually measures old-L-In 255mm shim w/ 0.102mm clearance - SAE feeler gauge new-L-In 245mm shim w/ 0.202mm clearance - not actually measured old-R-In 260mm shim w/ 0.102mm clearance - SAE feeler gauge new-R-In 250mm shim w/ 0.202mm clearance - not actually measured Second clearance check was March 22, 2008 @ 8,721 miles and I bought a metric feller gauge to check the final clearances (not initial clearances): old-L-Ex 250mm shim w/ 0.203mm clearance - SAE feeler gauge new-L-Ex 245mm shim w/ 0.220mm clearance - metric feeler gauge old-R-Ex 250mm shim w/ 0.229mm clearance - SAE feeler gauge new-R-Ex 250mm shim w/ 0.210mm clearance - metric feeler gauge old-L-In 245mm shim w/ 0.178mm clearance - SAE feeler gauge new-L-In 245mm shim w/ 0.170mm clearance - metric feeler gauge old-R-In 250mm shim w/ 0.203mm clearnace - SAE feeler gauge new-R-In 250mm shim w/ 0.170mm clearance - metric feeler gauge Third clearance check was August 9-10, 2009 @ 17,500+ miles: old-L-Ex 245mm shim w/ 0.220mm clearance - metric feeler gauge new-L-Ex 245mm shim w/ 0.230mm clearance - metric feeler gauge old-R-Ex 250mm shim w/ 0.200mm clearance - metric feeler gauge new-R-Ex 245mm shim w/ 0.250mm clearance - metric feeler gauge old-L-In 245mm shim w/ 0.190mm clearance - metric feeler gauge new-L-In 245mm shim w/ 0.200mm clearance - metric feeler gauge old-R-In 250mm shim w/ 0.190mm clearance - metric feeler gauge new-R-In 250mm shim w/ 0.200mm clearance - metric feeler gauge Not sure why some gaps 'grew' without changing shims. I'm using a KD Tool feeler (not junk) and tried all sorts of blade combos to verify the gap. In the end, it all seems to be in spec at the good end. I'll check it again around 30,000 miles.
