Feeler Gauge for valve check

Hey guys... I'm doing the valve check on my 990 ADV and am trying to find the right feeler gauge for the job. Mainly trouble finding a metric gauge. Do you all just convert to mm?

A link to one online would be awesome !

Thanks and Happy Holidays !

0.10mm=(.004") inch is rounded off, mm is true
0.13mm=(.005") inch is rounded off, mm is true
0.15mm=(.006") inch is rounded off, mm is true
0.18mm=(.007") inch is rounded off, mm is true
0.20mm=(.008") inch is rounded off, mm is true
0.23mm=(.009") inch is rounded off, mm is true

Pulled this from somewhere long time ago for some reason, maybe helpful?
Dunno, can also find metric gauges at pepboys, Here
first place I looked, if non US, well I would check any auto repair place.

Thank you.. This helps.

I found this in the right sizes. Do you think the handles would help or hurt?

KTM offers a set of metric feeler gauges for a few bucks.

Luckily, the ktm cannot tell a difference between metric and standard valve lash.

Until recently, I used inch gauges and converted. The precision involved in valve clearance checks is not that high and you can certainly get acceptable results doing this. But you will get a little bit of extra precision with metrics - the worst-case roundoff error can conspire to be significant - I think I computed once it can be as much as 50% or the increment in shim sizes. So I got a metric set recently. They're surprisingly hard to find at US stores, so I bought online (perhaps on Ebay) - they're made by KD. But one thing I don't like is that they start out at 0.04mm with 0.01mm increments, but go to 0.05mm increments abruptly at 0.10mm. This means doing something common like 0.12mm (a typical intake valve spec) requires stacking two gauges.

Thank you all for the help. I have the feeler gauge issue worked out now.

I have everything apart and have checked the valves.

I have one intake on the front cylinder that is right at .10 (i can get the .004 feeler gauge in but not the .005) This being in spec but at the low end should I re-shim it to the other end of the spec?

Thanks again... This has only taken me a week to get this far.

You'll get lots of opinions on this... mine is that if a valve is within spec, then leave it alone, especially if it involves pulling cams that otherwise can remain undisturbed.

and it's worth about that much. Few blades so hard to nail down clearances with the possible combinations. DAMHIK

Google-up your local MAC or Snap-On Tools dealer and find out his schedule in your area so you can meet his truck somewhere. You can usually find them at all the major shops in town at least once a week depending on where you live.

They have feeler guage sets like you won't believe- and they don't cost as much as you'd think. There are metric sets that go down to very small thicknesses so adding blades to get a good read is easy. Get some with long tapered blades as they fit in between the cam bridges easily. Furthermore they actually sell replacement blades if you ever damage any in your set.
