Just checking, too many use the wrong oil for the wrong reasons:s
got a 98 Fatboy, and have run 20-50 synthetic since I purchased. I don't run gear oil and never have in the primary. I don't get too wound up on name brand just the weight and synthetic. Try some good old Mobile 1 20-50 synthetic. If the clutch slips stay at the same weight and go with a dino oil. Good luck.
