is the primary oil the same as the oil in the swing arm
NO
Engine case has window passages cast into same. all XB-XL-XR castings principally operate the same. The Primary drive assembly and the transmission share ONE QUART of common fluid. It is NOT shared with the engine.
Primary/Trans refill with full one-hour drain is 1 US quart
Engine oil goes into the swingarm cavity via the dipstick/fill hole. capacity is 2.5 US quarts with full drain and filter replacement
READ your owners manual and/or the service manual for recommended lubricants and viscosity. this will avoid the dreaded "God Almighty not another idiotic oil thread" event so often seen on here.
I own FOUR Buells and FOUR XR1200's. i also service approx. 25 Buell XB's per annum.
My personal choices?
any quality 20W50 natural or synthetic for the engine. they're all excellent these days.
Mobil 1 V-twin 20W50....Amsoil 20W50 V-twin....for the primary/trans. both provide proven longevity....incredibly smooth clutch operation....well-balanced smooth shifting....fully STATOR/ROTOR compatible.
Avoid temptation to try ATF....gear-lube....Royal Purple in the primary/trans. why? many are NOT compatible with H-D stator/rotor assemblies and many are NOT JASO-MA/JASO-MA2 rated. an oil not rated as such typically causes "wet clutch" problems including slippage and welded-together plates in the pack. motorcycle oils marketed in the USA are NOT required to be SAE rated...but if specific designations on the container elude to "motorcycle usage"....they're typically JASO rated.
NOTE: the primary and swingarm drain plugs interchange. both require 5/8th socket or wrench to R&R. each has 1 sealing O-ring on same. closely check said O-ring doing initial service. probably never changed before and good idea to do same.
