Valve Check

I finally had a day off and decided to do a valve check. I assumed this was done at the place I purchased the bike since it had 9500 miles on it already. As you all know, never assume anything.....I'm thinking these have never been adjusted by looking at the exhaust clearances.
Below are my numbers and the shims "I think" I need to order.....if someone could give me a sanity check that would be great.

Left exhaust: .004 with 265 shim
Right exhaust: .003 with 260 shim
Left Intake: .005 with 260 shim
Right Intake: .005 with 260 shim

I "think" I need these:
Left exhaust: 252 to bring it to .009
Right exhaust: 245 to bring it to .009
Left Intake: 255 to bring it to .007
Right Intake: 255 to bring it to .007

Does this sound right?

Neither of my exhaust valves were in spec, but I don't see any signs of burning or scarring and my bike always fired right up....just glad I checked them now instead of putting it off again until Winter.

thanks for reading

AFAIK the valve shims are only in increments of .05mm in which you would need a 250 for the left exh. making the clearance .010 in.

Gray-haired riders donít get that way from pure luck.

Good reply flash!
For clarification each .05mm increment equals .002in change. The shims are only available in .05mm increments. You are better off with a tiny bit too much clearance than a tiny bit not enough!!

Actually .00196850394 in. But what's a few tenths between friends?

Seriously, why the U.S. doesn't embrace metrification is beyond me. Simple, if you can count to ten and do a little division / multiplication it's much simpler.

Is "simpler" even a word"? Spelling Nazi's fire at will......

Yeah, but it's much more simple to say simpler. I shall submit this to the Oxford.

We are, flash, we are.

Inch by inch, we're getting there.

p.s. Easy to remember that a millimeter is 40 thousandths of an inch (.04). It's actually 0.0393701", but even the Canadanians will cut us slack on the difference.
