How do you replace the primary chain on a sportster?

To replace the primary chain on a Sportster, first, remove the primary cover by unscrewing the bolts and detaching any attached components like the derby cover or clutch cable. Next, remove the old primary chain by loosening the adjuster and taking off the clutch assembly if necessary. Install the new primary chain, ensuring proper alignment and tension, then reassemble the components in reverse order, checking for correct operation before closing the primary cover. Always refer to the service manual for specific torque specifications and procedures.
