Hi.What kind of gear oil sould i use in my transmission? My local dealer recomends synthetic 20/50 H-D oil but i dont think it's right for my XB9.Thanks

thats right, it will work. I run royal purp 20/50 max cycle in both holes with great results. Heard the same about mobil 1 20/50 also. 20/50 is the right weight, when picking a synthetic make sure you read the bottle and make sure its compatible with wet clutches
