Well after careful consideration on what oil for what holes here it is. Engine & Primary M1V-Twin 20-50. Trany Mobile syn 75-140. I know there are alot of gear heads out their, and alot guys that know their stuff. I did read alot of the self help & forums was alittle confused on all the different models and their requirements. Is this a tumbs up or down for my r 08 Electra Glide Classic 96ci.
