Material Needed

  • Socket set

Step 1 – Inspect the covers

They might be loose.

Check all the outside covers and trim. As we mentioned above, the Harley vibrates aggressively, so overtime the parts attached to it might get loose and cause a bit of a rattle. Check the engine cover by wiggling it with your hands. Check the plastic trim holding the tail lights in place. Check the mirrors and the switches. Then, check the floor boards to make sure they aren't loose. Finally, make sure the brake and clutch lines aren't causing the rattle. They should be fastened alongside the forks.

If the trim and covers are all attached properly, proceed to Step 2.

Step 2 – Check kickstand

It could be loose.

The kickstand tends to get loose after a while. It's one of the most used parts on your bike, as you lay your bike's weight on it daily. Overtime, the bolt holding it in place could get loose and as you rev your engine or even drive normally, it could shake a little, which causes mild metal-on-metal rattling. The spring attached to the kickstand could also come off one side, which would cause a consistent rattle as you drive; however, if the spring came off, you would be able to tell as you're kicking it back. If it is loose, use your socket to tighten the bolt holding it in place.

If the kickstand is tightly in place, proceed to Step 3.

Step 3 – Check the exhaust

It could be loose or has a loose cover.

The exhausts are attached in place by a few screws and brackets, so if one screw is loose, a rattling noise is guaranteed to come up. Check the exhausts from where they attach to the engine and make your way to the rear. Wiggle it and inspect any brackets along the way. Make sure the second layer (cover) on top of the exhaust is tightly in place. If any parts are loose, tighten them, and if you're missing screws, simply buy the right size from any auto store.
