Anyone notice more gear/chain noise w/ Amsoil 20-50 in their tranny? Runs fine, shifts better, just louder. Thanks.

 

From Experience with Amsoil in my other bike...Everything Is Better with Amsoil.

Tomorrow I am having my 1,000 mile service done and I am having Amsoil put in. So Ill let ya know.

 

I run Amsoil in my bike's trans an it sounds fine,,,have you adjusted your primary chain,,( 2003 883 w/1200 conversion and Andrews N4 cams )

 

From amsoils site....
20w-50oil may be used in all three - Engine, Transmission, and Primary Case as specified by the H-D Motor Company, however Harley Performance recommends using a heavier 75w-90 gear lube in the transmission. Both methods exceed the manufacture's and API specification and will not void any warranty.

 

Yes, Gear Oil is preferable over Motor Oil in the primary/tranny.
However, Gear Oil is measured on a different "viscosity" scale than the one used for Motor (Engine) Oil.
A 75-90 Gear Oil has roughly the same viscosity as a 20-50 Motor Oil.
