Well I measured it on a granite block and I couldn't get a 0.001" gauge under so I think it's good. It would still be nice to know the max warpage though, if anyone knows, thanks.
I think I have my manual for my old 700 sx, should be the same. If I can find it I'll get you the specs. Sounds like you're in good shape though, A thousandth doesn't seam like a lot.
Not sure if you can see this attached picture or not. I can PM you a better picture if you wish. The Warpage Limit is 0.03mm or 0.0012 inches. I'd say you are good to go.
I see you live in uxbridge, I'm not far from you I live in Stouffville.
