what weight is the harley tranny oil ???

 

They don't publicize that do they&nbsp\\;but it is heavier than the SE&nbsp\\;20 -50&nbsp\\;synthetic . I use Amsoil 75-40.&nbsp\\;

 

thanks gum i use amsoil too a great product 75-40 is heavy enough i was thinking
about using the severe gear oil which i think it&nbsp\\;is 85-110

Used oil analysis reports show it to be a 50w. With a very light additive package.
