A question on Amsoil for you. I saw a while back where you recommended 20w50 in the motor, 75w140 in the tranny, and Super shift ATF in the primary. I wasn't able to locate a Super shift that specified "ATF" do you have a product code for it?
Also, what kind of filter are you running for the oil. Just looking for a screw on replacement for a 03 night train
