If it has fine teeth on the drive shaft I think it will be a 3AJ 88/89
I think the front sprocket on the 3AJ has a shoulder on one side so if you have a flat sprocket some one may have tried to space it out.
The xt600 used different size sprockets
1986/87 15/40 104
1988 15/40 104
1989 15/45 106 This model uses the sprocket with fine splines
I have several XT600 micro fiches on cd but no 3AJ, my local bike shop had a micro fishe for the 3AJ but have since changed over to a computer system and dont have 3AJ on the system.
You could try looking in the Kedo catalouge for info on sprockets
Kedo should be able to tell you what engine you have and are very good for spare parts.
