Working on an electrical issue on my 97 Ural 650.. soon as I turn the key switch the top fuse blows.. I opened up the fuse box and it appears the top right screw is missing.. should there be a screw/wire there??

Also the wires on the right of the fuse box are a bit "burnt" looking... The headlight, running lights, instrument panel lights all work fine

edit:  Found this diagram online (appears to be to a 1992 Ural 650).. not sure if the diagram would be the same for a US model 98 650

Your electrical diagram shows why there is no screw in the upper-right hole:
That connection is made by a metal bar on the underside of the fuse block.  
The diagram shows that bar as a gray line.

A blowing fuse probably indicates worn insulation and a short to metal on those kill-switch and flasher circuits.
You should be able to trouble-shoot those with an Ohm meter.

The "burnt-looking" wires on the right side look like they got sprayed with black paint when someone did a little paint touch-up on the bike.
Let us know what you find to solve the fuse blowing.

To help debug the wires you can remove the blown fuse and then use alligator clips to fasten a test light in it's place. The short will just light up the bulb when you turn the key on, and you can start wiggling connections etc. and if the light suddenly dims or goes out you have found the short. Note that even when all is right the bulb will glow some due to the load on the circuit.

With the bulb in place this will prevent melting wires etc. while you trace.

UPDATE!!  Fuse box was correct, thanks for the info.

The short was caused by a frayed wire on the killswitch that was touching the handlebar.  I cut out the old wire and put in a new one.. Bike is up and running again :)
