Lubricants

 

Engine
         400 F and above SAE 20W/40, SE-SF
         400 F and below SAE 10W/30, SE-SF
         Brake Fluid DOT 3 or DOT 4 or DOT 5.1

Concerning Brake fluids.  Dot 3, 4 & 5.1 can be mixed together for they are all glycol-based.
Dot 5, however, is not compatible and can not be mixed with any of the above brake fluids for it is Silicone based and can not, repeat, cannot be mixed with any of the above brake fluids. It has a distinct color bluish-purplish color.  http://www.clearcoproducts.com/dot5-brake-fluid.html
The chart makes it look as though it can be mixed “DOT 3 or DOT 4 or DOT 5”.  If Dot 5 is to be used, the whole braking system will have to be purged of all of the glycol-based fluids and Vice Versa.
*Edit from ViragoJoe, He might have just saved a few brake systems from this added knowledge*

 

 

         Battery Refilling Distilled water
         Fork Oil SAE 10
         Cables & Pivot Points Yamaha chain and cable lube or
SAE 10W/30 motor oil – regular
         Fuel 87 Octane – unleaded

*NOTE*Also, Fuel Octane is 87 not 89 – unleaded.  Unless there are exceptions that are higher compression, but I believe the bulk of Virago’s are 87 Octane*

*Edit provided by ViragoJoe*

Final Gear Oil (SHAFT DRIVE)
         All Weather SAE 80W/90, GLA
         Above 400 F SAE 90, GLA
         Below 400 F SAE 80, GLA
Drive Chain (CHAIN DRIVE) Shell Alvania 1 or lithium-base EP-2 grease
