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.
