Will a stock chain work with 15/38?? I have searched all over and can't find the answer.

No. You will need a shorter or shorten the chain. (102 links) I would go with a 15/41. A 15-41 set up results roughly in 1000 rpm per 10 mph in 6th. The engine is doing about 5750 rpm at an indicated 60 mph and spinning at about 6900 at an indicated 70 mph. You just may need to spend a little more time in 5th than a stock bike if you live in hilly area or are riding in a stiff headwind at highway speeds. Passing can be done comfortably in 4th or 5th. 6th still has a little bit left depending on rpm speed.

You are right, after much measurement and calculations I conclude that the slot is not long enough for 15/38 with 106 links. I am running 15/41 at the moment and my measurements indicate that with 102 links the axle would be so far forward that it would be nigh on impossible to get the chain on! So I will have to go with 104; axle just a tad further forward than 15/41 with 106.
Have you any idea if one can shorten a stock chain, it's almost new, but where would one obtain a master link that fits??

The stock chain can be cut and riveted with the right tools. The stock chain is a EK520 SRO (at least mine is). You should be able to find the proper links if it is the same.
Here are a couple of places you can try;
