What was the serial number cutoff in the 1985 Model year where the second gear problem was fixed in production?

I have a line on an '85 and want to verify that it has the "improved" transmission components.

The serial number as per the service bulletin is
serial number 59J-000100~0001413 had the softer thrust washers as well as all 83 and 84 models.

The important part are the actual the ~001413 was the last one with the soft washers. They started at ~000100 numbering the 85 builds, so ~001061 was in the old soft washer build. Yamaha built the 83, 84 and early 85 Ventures with these soft thrust washers....then after that....installed a harder washer to remedy the issue.
If you don't flog the bike...the 2nd gear issue might not show up till the 50,000 mile + range. Its a gradual thing, not a yesterday it was fine, today it won't stay in 2nd thing.
