Yamaha YR3 gearbox oil

[stresa]

Hi all,
a guy on a german Facebook site has bought a YR3 and is a bit struggling to find data for that bike. Very rare bike overhere.
How much gearbox oil to fill in that engine please?

I had the same problem with my YL1, no dip stick and no data on how much oil. I think they use a dip stick that is in the tool kit. Here is what it looks like for a YR3:  https://www.classicracing.nl/product/gauge-level-168-15361-00

Hi Uwe,
The R3 gearbox oil capacity is 1200cc
I also included some service data specs I found in my files that may be useful (sorry about the poor image quality)

Thanks @1976RD400C and @SoCal250
That will help. The YR1-3 range is very rare overhere. I doubt that more than 2 dozen bikes are on the road
