Is the smoke a white/blue in color? if so your most likely burning oil, and when the metal heats up its expanding and sealing the slow leak. This should be easily tracked by watching your oil level.
If that is the case you have a gasket gone bad some where in the mix, and its time to do a rebuild on the motor. Have no fear, its fun and not all that hard, just time consuming.

Could be oil physically dripping onto the exhaust, burns off as it heats up.

I read somewhere in the 650 centrals site that the valve seals get hard after 30 odd years and weeps oil down the valve. There is a tutorial on how to change the seal with the motor in the bike with a few home made tools(no top end tear down needed). Im thinking I,m going to have to do the same thing on my 81 as it smokes at start up and go's away after the engine warms.

can you post the link to the tutorial? i cant seem to find it online. Thanks in advance
Mostly likely the seals have hardened from old age,if you proceed to replace them,get your new seals off ebay from the guy who sells HP/Products for the XS ,they are a viton seal made to endure the heat cycling, prolonging the seals life

on 650 centrals web site go to the left side of the main page, at the bottom there is a list of small tidbits. all I can say is go through the list and you will find it.

I'm pretty sure Jack just vouched for them - and he knows his way around an engine...

He never said specifically that he had used them. I assume he had, just looking for verification.
