I would start with the basics, like has it got a spark, also carbs may need a good clean. The starter jet in the float bowl is tiny and gets blocked real easy, bad part is you cant remove that jet to clean you have to do it in situ.

You might want to put some fuel in it.

I had a similar problem: my '86 was really cold blooded and then one day it just died on me for apparently no reason. For me, the problem was carb synchronization. Now it runs better than ever. I tried all that you did, with no result, so I found a dealership that would work on older bikes. Hope this helps.
