I went for a ride with a few friends, all of us having Harley's. When we stopped my bike was just clinking and pinging away as it cooled down. Their bikes were not making any noise. (Mine has always made the noise since I got and didn't realize that they all didn't) I know that the noise is just the metal contracting as it cools. I'm wondering if the bike is actually running too hot or if it is the difference between the slip-ons I have and the stock pipes they have. Any ideas?

 

not a clue.. i thought they all popped and clicked on cool down. I know my fb sure does.. as does all my cage rides..

 

Supposed to be hot oil dripping down that makes that noise. Mine does it all the time as well as my Vette.

 

mine made alot of noise when i had stock exhaust but near as much since i changed to true duels

 

You and I are probably the only two people on this forum who have this problem. Glad to here
I am not alone in running stock pipe. The other day a guy was bragging or moaning his bike was stock
yet he had changed the exhaust as if this did not count.
I bet it is your hose type SS banding that retains your front and rear heat shields on your stock exhaust.
You may want to slight loosen the one on each shield on both pipe and get
the exhaust hot. When you stop with a heat glove on tighten the screw snug. Does not have to be
real tight. It may help. I drive year round and last winter when I pulled in the garage and it was
about 32 degrees and I cut it off I could still hear it in the house. I did the above and it helped. Since I
know what it is it does not bother me. My bike is pretty old and ragged but the exhaust came off
a new take off and to me makes it sound new at least when it’s off. HA

 

Every harley I've been near while it cooled down has pinged/clinked.

 

Mine pings too, sounds like a clock sometimes, when I start it you can't hear the pings anymore.

 

Love that sound. Sittin in the garage drinking a cold one after a long ride justs lookin at it with a grin on my face.

 

You didn't mention if your friend's bike was liquid cooled. Usually no contraction noises. Air cooled engines are built to different tolerances to allow for expansion/contraction, thus a normal noise. Also, the "looser" tolerances contribute to oil consumption, not as much as HD claims is normal, but still some normal consumption. Remember, air cooled engines only have air, oil, and fuel cooling them. Add a radiator and you have an entirely different animal.

 

I thought it was the chrome cooling that made the ting ting noise. Maybe their bikes don't have as much chrome?
