Front Shocks - Clunk Sound

[coachluciano]

Question, I have upgraded cartridges in my front shocks been riding them for probably 3k miles. They work great especially with the 535 rear shock. Sitting still and grabbing the front brake and pulling up hard on the handle bars the back down, shocks are smooth as hell, but I hear small clunks when I do that. Wondering if it’s normal.  knowing what is inside the the shock tubes I’m struggling to figure out what is causing it. I’m not overly concerned, unless I hear otherwise for the folks here. Andreani inserts. Any insight would be worth a beer or two.

On other bikes, I've hard folks say the bearings in the head stem are making the noise. I've not confirmed this personally.

I’m going to get a video with sound (obviously) posted. I ride too fast to have an unknown possible issue  in my front shocks.  I’m not a huge fan of either Yamaha dealer near me especially when it comes to stuff like this.  I’ve learned more on this site than any one general dealer mechanic has in the brain matter area when it comes to the -09

Now that I think about it idiot Lucky Luciano,  no speed is good with potential front suspension issues.

My modified front forks are much noisier than OEM, with loud sucking noises if I hold the front brake and bounce the shocks. This is due to the larger holes in the cartridges allowing much more fluid movement. I wonder if your noises are related to that and perhaps the little one-way valves clicking shut when the fluid direction flow reverses?

[coachluciano]

Thanks for all the replies. Yes, it’s actually the fluid moving. Not sure why it jumped out to me as something I should be concerned about and why it was so loud that day. And yes, way louder than stock when it comes to pushing fluid though small holes.

Also likely the front brake rotor rocking back and forth on its floating mounts.

Yup - in fact it's a combination of all the answers I got back.  I guess I was overly paranoid that day.  I hopped on a new 2020 the other day and ran the same test.  Yes, the Andreani cartridges move much more fluid and it's noticeably louder.
