Should be 36 degrees BTDC full advance.
Do you have the number thats stamped into the dizzy body?
points gap is 15 thou, AAU range is 14 degrees. Pull the whole thing apart, give it a really good clean out and check for any play or bend in the shaft. you WILL need a strobe light to check timing "concurrence".
I posted a bit of stuff a while ago on 18D2, 3TA and checking timing on both cylinders for bikes fitted with a dizzy. Hopefully your 5TA has an inspection cover in the chaincase.
