1974 R75/5 oils and capacities...
I'll be acquiring a conversion bike in a few days. The engine in it is a 1974 R75/5.
I plan on using the Valvoline VR1 40 for the engine.
I want to double check with you all and confirm that it's okay to use the Sta-Lube Gear Oil SAE 85w90 for the transmission/drive shaft and rear drive?
It's API/Gl-4 oil.
I've got a Clymer's manual coming in the mail too.. but wanting to buy my oil ahead of time.
Thanks!
Rob

What are the capacities for the trans/ drive shaft/ rear drive?
I'm guessing to the bottom of the threads for trans and rear drive, but was kinda hoping for an amount so I can purchase the correct amount.
Thanks!

You can access an owner's manual in the knowledge base.
That'll give you oil recommendations and capacities.
Myself, I do use the Valvoline VR 1 engine oils, and the Sta-Lube in the drivetrain;
the Valvoline having a good amount of ZDDP and the GL-4 being hypothetically safe for yellow metals.
Both available off the Amazon.
Synthetics may be a slighty better oil but, (to me) not at the frequency of change with these bikes.
Best-

Re: 1974 R75/5 oils and capacities...
My only issue with GL-4 is a couple of things. First, I don't think there are yellow metals in the /5-on bikes. There was some talk that they are in the pre 1970 bikes, but honestly, I don't see the side of the road littered with broken down /2 bikes. Second, with the improvements in the helical gear sets, I think you're better served with a hypoid GL-5. It is designed for the newer style gears and meshing.

Fast. Neat. Average. Friendly. Good. Good.
