Tmx100 gearcase oil?

[mikefink]

This is my first antique two stroke and I was wondering what gear case oil you guys use? I have a 73 cb750 which I use 4 stroke 10w30 or 10w40, emphasis on the 4 stroke part! I already filled her up with 10w40 but I've only ridden two miles. I plan on keeping this bike for a long time!

Thanks!

I use 10w40 in my Bridgestone TMX works for me.
Thanks.
