    I have a Clymer manual that lists .004 " for the intake and .004" for the exhaust.  If the exhaust is off by a couple thousandths, will that have any significant effect on performance?

Your valve clearances should be:
Intake .08-.12 mm (.003-.005 in)
Exhaust .12-.16 mm (.005-.006 in)
I usually start all gaps in the middle of given specs, then fine tune from there.
Hope this helps

NO! that is incorrect! it is not 8-12 or 12-16

All of the Honda VT500 shadow's and ascot's Valves are 0.10mm all the way around for exhaust and intake

FT mark is for front and Rt mark is for rear cylinders.

Torgue specs for the 2 nuts on rocker arm

I may be wrong but there is no Spec. It is a matter of tightening lower nut until the Valves run quiet then tighten the other as a Lock nut so the lower one doesn't loosen up.
Or if it's a solid Lifter setup, you need to gap the valve with the lower nut to the correct gap then tighten the Locknut above

Anyone can help me answer this how to measure ring gap!

The ring should be placed down in the cylinder bore squarely(use an inverted piston with only the bottom ring installed to get it even).Measure the gap in the ring with a set of feeler gauges.(an assembly manual should list the spec).It is important the gap is correct-too tight will cause the piston to seize in the bore when it reaches operating temperature.Too loose,and you will have excessive compression loss and oil consumption.A manual ring grinder is fairly inexpensive(if you can fabricate your own like I did,it is even cheaper).

Why does my 1983 honda shadow 500 leak fuel out top of carbs when starting it

It does not close the fuel intake in the carb, it is the valve with rubber on top of valve, this valve is attach to float. When this rubber is dirty or worn it doesn't close the fuel when the float is at max, so the fuel goes out through upper rubber pipe.
