If you are a returning visitor to the forum and can't log in using your old forum name and password but used to be able to then chances are your account is deleted. Purges of the databases are done regularly. You will have to create a new forum account and you should be all set.

I think the normal philosophy around here is yes, 3-8 mm....for in and ex but its ok if the exhaust are a bit loose......but not required.
Download a free manual for you bike on Bass cliffs site.
The Suzuki manual is generally pretty clear on things.

I'v got some EX at 0.14, would you leave those alone ?

Strange indeed- make sure camlobes are orientated correctly, so an adjacent lobe doesn't give a false hign clearance on the one you are measuring.

I'm checking with the lobe facing forward on the EX at about 45 deg & the exact opposite for the IN.

Not sure that I understand how you are expressing this. As an example to check #1 exhaust, its cam lobe should be pointing forward , this also lets you check #2 exhaust at same time since neither of these lobes is pressing against a shim; and neither lobe is trying to push up on camshaft and distort reading
Did you read the Basscliff tutorial?

This procedure seems like you are measuring the clearance of only 1 valve at a time. As mentioned, this leads to improper position of cam lobes on adjacent cylinder, and could result in a larger reading.
Follow the correct OEM procedure as given in link above, and re-measure clearances.

OK checked again, some very slight differences, not enough to alter the replacement shim needed.
