Saries: Please clarify on the HD drain plug. Are you refering to a plug that uses an rubber O-ring glued to the bolt? I would use 26-29 on an compressible washer or copper or alum. normally. I would think that that torque high of torque would be too much on an O-ring and make it un-servicable later. I currently have it installed on the FJ and it seams to be working and holding just fine.Let me eloaborate a little on this.
I have had two Buells both 1200cc. I checked the manual on the torque specs for the 2009 XB12R.
For the Primary (Trans):
1. Wipe any foreign material from the magnetic drain plug,
inspect/replace o-ring and apply LOCTITE 565 THREAD
SEALANT. Reinstall plug and tighten to 14-30 ft-lbs (19-
41 Nm).
For the Oil (In the swingarm):
1. Inspect drain plug O-ring for tears or damage. Replace if
required. Wipe any foreign material from drain plug.
2. Apply LOCTITE 565 THREAD SEALANT, reinstall plug
and tighten to 26-29 ft-lbs (35-39 Nm).
Both drain plugs were the same size and had replaceable o-rings. I replaced them every other oil change.
HTH
