DS3604-0001, TRANSMISSION AND PRIMARY CHAIN OIL, XL Order Here
XL/XLH Sporster models require different driveline oil than the Big Twins. Drag XL oil is designed to be used only in the Sporster model and must be changed every other Engine oil change. The XL transmission, clutch and Primary chain are all lubricated with the same oil and collects a lot of metal particles. Not servicing these oils will cause premature bearing failure that can be very expensive.
