So I just recently bought a 79’ Yamaha XS750 as my first bike. Had to put a little work into it to get it running but now that it’s running, I’m on to the last part of my journey before she’s road ready. Since I’m new to bikes I have a very silly question. What type of oil do I use in the mid and final gear? Do I use the same oil as the engine oil or do I use gear oil? I’ve checked as many forums as I can and even looked at a pdf of the manual and I still don’t understand
