Motorcycle Repair: transmission oil, mobil one, synthetic oils

Question
98 dana superglide all stock,18000 miles,i use mobil-1 20-50 synthetic in the engine,can i use this oil in the transmission and primary?Thanks

Answer
I havent used Mobil One so it going to be tough for me to comment on it. I would check with the manufacture or where you buy it to make sure it can be used. If not there are alot of other synthetic oils you can use. Belray is a good one.
Good luck and happy riding
