This is my attempt an a complete Zaskar Identification Algorithm:
1. Rounded endcap on top tube (ie where it sticks out behind the seat tube) => no; never a zaskar
2. 6061 stamp (usually on inside right rear dropout, may be missing) => yes, always a Zaskar (unless someone has added a false stamp! has anyone heard of this?)
You have now divided most zaskars and non-zaskars! The only bike that can now confuse you is a 92 or 92 Pantera - the only other GTs to have flat endcaps. (True???)
3 If bike has u-brake and is ball burnished => Zaskar (only the 92 version of Pantera had a U brake and it didn't come in bb finish)
4. Try using the serial number (look at inside left rear dropout - but some bikes don't have a serial number). Then:

Here is an email I got from an actual employee of GT:
If the bike frame was manufactured at the Santa Ana CA facility, the first three or four digits of the serial number should be letters abbreviating the model or size of the frame such as "XL", "XXL", CR24, or something like that The next part of the serial number is eight numeric digits. The first four numbers should be a two digit month followed by a two digit year. The last four digits are the serialization digits 0000 to 9999 depending on what number the frame was of the years production.
..But non-American frames have a different serial number style - it starts with a letter that codes the frame maker, and possibly uses another let to ocde assembly country, and then two letters to code date:
if your serial is KGCG2297 this one gets a little complicated. but still easy once you learn the code to it.
the first letter is who made the frame itself, in this case it would be "Kenisis", an overseas company.this could be replaced by another letter but at least we know what that one is there for.
next is the letter "G"..this isnt always there, but if so, this is where it was assembled, (ever notice the built in usa sticker on your gt or dyno?) this is what that letter is there for. it wasnt made here, but was built here.
next is the letter "C"..C is the 3rd letter in the alphabet, and march is the 3rd month, so march is the build month.
next is the letter "G" this is the year. G is the 7th letter in the alphabet, so this would be a 1987.
If the frame number is American style, then you have a Zaskar - because all Panteras were Taiwanese made. But if the serial number is Taiwanese style then ou MAY have a Zaskar - you need to work out the date from the code and see if it is after the date (2000???) that Zaskar frames started to be built in Taiwan. That's if you count Taiwanese Zaskars as the real thing - there's a change in tubing, at least in name.
5. If there is no serial number, the bike is probably a Zaskar, because no one has recorded a Pantera with no serial number (???)
Questions:
- Is there anywhere you can look for a 7001 stamp on a Pantera?
- Were Taiwanese Zaskars built of a proprietary (columbus?) tubing that would have had its own stamp instead of 6061?
- Do Taiwanese Zaskars count as Zaskars?
Notes:
- Spankys serial number = yes, 91 Zaskar!
