XS750 3 Oil Change - Final Drive, Mid Gear, Engine and Filter

Time to change all 3 oils on the 1978 Yamaha XS750S, and not a moment too soon. The Final Drive and Mid Gear oil were changed 3 years ago when I first started this project and have about 3600 miles on each. Let's just say the oil I chose didn't hold up like the original!!!

Oils and Filters Selected for this maintenance:
Oil Filter - K&N 146
Engine Oil - Spectro 20-W40
Mid Gear and Final Drive - Bel Ray Hypoid 80W90
