1.Primary Chain Tension:
- Verify the tension of the primary chain. If the chain is too tight or too loose, it can create a ticking sound as it moves. Adjust the chain tension according to the manufacturer's specifications.
2. Damaged Primary Chain:
- Inspect the primary chain for any damaged or worn links. A damaged chain can produce a ticking noise as it engages with the sprockets. If the chain is damaged, replace it with a new one.
3. Tensioner Issue:
- The tensioner is responsible for maintaining proper primary chain tension. Ensure the tensioner is functioning correctly and is not stuck or damaged. If the tensioner is faulty, replace it.
4. Starter Clutch Bearing:
- Check the starter clutch bearing for any wear or damage. A worn or damaged bearing can produce a ticking noise when the starter motor is engaged. If necessary, replace the starter clutch bearing.
5. Clutch Hub Bearing:
- Inspect the clutch hub bearing for any signs of wear or damage. A faulty bearing can cause a ticking sound when the clutch is disengaged. Replace the clutch hub bearing if needed.
6. Damaged Gear:
- Examine the gears inside the primary cover for any damage or wear. Damaged gears can produce a ticking noise as they mesh together. If any gear is damaged, replace it with a new one.
7. Excessive Clearance:
- Check for excessive clearance between the gears and the primary cover. Too much clearance can create a ticking noise as the gears rotate. If necessary, adjust the clearance according to the manufacturer's specifications.
8. Oil Level and Quality:
- Ensure that the primary has the proper oil level and that the oil is clean and in good condition. Low oil or dirty oil can cause various noises, including ticking sounds. Change the oil and filter if needed.
If the ticking noise persists after you have checked all of the above potential causes, it is advisable to consult with a qualified Harley-Davidson mechanic for further diagnosis and repair.
