Have manual--don't have access to it per the OP.  Looking through the online version that is stickied at the top of the forum now.

I'll assume the clutch plates are OK and just switch out the friction plates.

You're telling me to "look at the link provided."  This link ([url=http://www.vulcandrifterriders.com/clutchparts.html]http://www.vulcandrifterriders.com/clutchparts.html[/url]) says to use 92144-1394 clutch spring for my 1999 1500.  You used the "current" spring (92144-1295).

No, you don't want to use the original spring and holder... you want to UPGRADE  - use the parts listed at the top of that page. The original part has been superseded, so use the newest one. And, you use the TWO holders. This spring and holder combination should resolve the weak spring issue we had on all early 1500's.  The colored chart simply shows the evolution of the spring plate/holders for the 1500.

This page may be of more help. There is a section on Judge's washers... that was an upgrade before KAW re-engineered the spring and holders. Some people like that mod, I didn't think it necessary and didn't do it. Same with using a 2004 MS spring... not needed now, in my opinion.

You should always measure the clutch package after replacing the friction plates to ensure it is still within specs. Usually it will be, but best to check. If you have to, you replace a steel plate with an undersize or oversize plate depending upon the thickness you got.

I'd look in the Clymer manual but I lent it to my mechanic (cousin) who currently has my Drifter in pieces on the floor of his shop :-)

GET A MANUAL!

There is no substitute for a manual. Look at the link provided.
The current spring is what the Kaw engineers are putting in ALL 1500/1600 vulcans... and has been for a while. That is what I have in mine (with updated holders).
You can look up and review the various types of friction plates to determine which is best for you. I used the barnett friction plates and didn't need to change out the steel plates. The friction plates are the same size as far as I remember. The steel plates are all the same size, with one plate used to get the right package thickness... undersize, standard, and oversize.
Again, do yourself a favor and get a manual. They are usually about $40-50.

Are the cork-aluminum friction plates good? Are fiber ones better? What is the best?

How many clutch plates of 13089A/B do I need? One of each? Which thickness--looks like there are three options?

What about 92145-1243, of which Partzilla says I need 10 ea.?

Personally, I went with the current spring and upgraded to two holders. I replaced the FRICTION plates only. You need to measure the complete package to ensure it is within specs. You have the link to the parts listing and info.

Clutch problems with my 1999 1500 Drifter... torn down for fixin'. Could use your help--comments appreciated.

1. I see some use clutch spring 92144-1934 (early Mean Streaks), some 92144-1295 (2005+ Mean Streaks). Is one stronger?

2. Planning on upgrading to dual holders (13280-1306 and 13280-1307).

3. I understand there are 8 friction plates (13088)--are the cork-aluminum ones good? Are fiber ones better? What is the best?

4. How many clutch plates of 13089A/B do I need? One of each? Which thickness--looks like there are three options?

5. What about 92145-1243, of which Partzilla says I need 10 ea.?
