I have found that amsoil is easier to get than spectro if you can believe that. non of the bike shops carry the M1 and Wal-mart stoped selling it, so it kinda comes down to amsoil or spectro for me. Wich one do you think is the best? Im kinda goofy on the fact that i like to use the same brand in all three holes rather than differnt oil and trans and primary. you know, one stop shopping.
		
		
	 
OK.  So for almost "one-stop" shoppers, here is the layout (EVOs and TCs):
Amsoil:
Engine:  20W-50 Advanced Synthetic Motorcycle Oil Product Code: MCVQT-EA 
Tranny:  SEVERE GEAR® Synthetic Extreme Pressure (EP) Lubricant 75W-140 (SVO) or
             SEVERE GEAR® Synthetic Extreme Pressure (EP) Lubricant 75W-90 (SVG) depending on local temps
Primary: HD Formula Plus or Spectro Heavy Duty Primary Chaincase Oil
I DO NOT USE THIS, BUT IF I WERE GOING ONLY WITH AMSOIL ONLY, I WOULD TRY:
Primary:  Super Shift Racing Transmission Fluid SAE 10W Product Code: ARTQT-EA  
Mobil 1:
Engine:  Mobil 1 V-Twin 20W-50 
Tranny: Mobil 1 Synthetic Gear Lube LS 75W-140 or
            Mobil 1 Synthetic Gear Lube LS 75W-90 depending on local temps
Primary: HD Formula Plus or Spectro Heavy Duty Primary Chaincase Oil
Spectro:
Engine:  Heavy Duty Platinum Full Synthetic 20W-50
Tranny: Heavy Duty Platinum 6-speed Transmission Oil (6-spds, GL-5) or
            Heavy Duty Platinum Full Synthetic Transmission/Gear Oil (GL-1)
Primary: Spectro Heavy Duty Primary Chaincase Oil or HD Formula Plus
Redline:
Engine:  Synthetic Motor Oil 20W50
Tranny:  ShockProof® Gear Oil: V-Twin Transmission Oil with ShockProof
Primary:  Synthetic Gear Oils: V-Twin Primary Case Oil
You guys that use Mobil 1 in everything might have a suggestion for the Primary fluid.  I just have not tried an auto transmission fluid from them in the my primaries.
