I just had handle bars put on by bike and the mechanic had a few choices for trans. oil. I opted for Amsoil since I had heard good things about it here. I think it was 75/140 Gear oil, but will check tonight for you. Anyway... Wow! What a major change. As soon as I popped it in gear I could tell something was different, in a good way. Feels like a different bike now... very smoothe. I'll be staying with that in my trans.

I have been using Mobil 1 GEAR OIL 75/90 or 85/140 for the last 50,000 miles.
Excellent smooth results!

Mobil 1 V-twin in the engine and Mobil 1 gear oil in the tranny.
Motor oil in the motor and gear oil in the gears.

Then there are some of us who swears by Redline Shockproof Heavy. What ever brand you use, Just use GEAR OIL ! My $.00001 after Stock Market decline.
