Harley Primary Oil

Which Schaeffer's oil products should I use For My  Harley Davidson's Primary Drive?

I have been using your Schaeffer #705 20W-50 racing oil in my primary drive for some time now in my olderSchaeffer primary oil Harley.  I have purchased a '07 Harley and want to continue using it but I am wondering if there is something better. What do you recommend I use in the transmission and the primary drive? I have no problem using the #705 SAE 20W-50 in the transmission, but what do you recommend for the primary drive? Any other information related to this would be greatly appreciated. Thank you too for your assistance.
