Question Front end "CLUNK" ?

Was out for a ride this weekend, on two occasions, I hit a dip in the pavement, and "CLUNK" it almost sounded like the front forks fully extended and "bottomed out" on full extension, this is a new noise to me, when it happened the second time the wife said from behind, What the hell was that? it was a real loud bang! This kinda worries me, anyone else experience this ? any replies would help.

Do you have the HD Profile lowered front springs installed by chance?

We really need to know:
Is the front end stock?
What year, model and mileage?
before offering any educated opinions.

And as a result of lack of information....let the uneducated opinions fly. Dropped your beer can?

Seriously now....at 30k, you're due for some fork maintenance anyway....fluid change at a minimum. Might have blown a valving o-ring and indeed bottomed out hard. Try to replicate to establish a pattern so you have something useful to tell your mech.

Another thought....put it on a frame lift and check the head bearings. Usually you'll get a crazy wobble at certain speeds when they lossen up but I had a scoot a while ago that rode fine until I hit a bump....clunk....head bearing was bad. Other than that, check all the usual suspects...brake calipers, wheel bearings, axle nuts, or other loose/interferring hard parts.

Good luck.

I had something similar on my last bike , 06 FLHT.
First time was a broken upper fairing bracket , covered by the dealer.
The second time and quite a bit louder was the 2 lowest screws for the fairing that you access by turning the forks , one was missing and the other was about ready to fall out.
Blue locktite and a new screw fixed it .
The loose screws thing was really loud and made me nervous as heck till I found it.
Just a couple things that did happen to mine.
