Metal-on-metal smack from front end when hitting pothole or rough road

Hornet newb here - been lurking for quite a while and collecting threads but couldn't find anything specific around my particular issue: when I hit a pothole at city speeds (20-30), there's a pretty loud metal-on-metal smack sound from the front end. When I'm stationary on the bike and I bounce down on the front, it doesn't seem possible that the brace/triple tree would be colliding?

Don't even know where to start... On my Honda '79 750, '75 550 and '75 360, I know I can pop off the fork covers and check the fluids, but the 2000's make me nervous.

If your fork is topping out, they can make a pretty wild clunk, could be an issue with not enough sag or low fluid level. Perhaps check your stem bearings as well, if they wore/ got loose, that could flip around as well. Good luck and let us know what you find!

Bad/worn steering stem bearings???? Do you do a lot of wheelies?

How many miles on the bike? My 07 with 16k has similar feel but seems to come from the rear at very slow speeds.

Make sure your front caliper mount bolts are tight.

I'd start with looking at the adjustments, fluid level and fluid age. Always inspect all bolts in case something has worked loose.

I don't know what adjustments you have on those forks, IIRC, it depends on the year '04+ are adjustable, don't know about the < 04.

It could be the springs are worn or something clogged up in the valving.

Not to worry; they used '70s fork technology on the 9'er You can pull them and check Try to find a way to get the weight off the front, though.

Maybe the best way to check is to take off the tops, remove the forks from the triple trees, turn them upside down to drain the fluid. Refill with new fluid.

Don't have to do a big tear down.

It's not much more work at that point to pull the whole mess out and rebuild it (I use that term loosely, just replacing bushings and seals) and actually flush the goo that's left at the bottom out...
