I really hate to bring this up again. I did a search and in all the previous posts I did not see any resolution to this problem. Although I have not checked the steering head bearings, yet, the noise appears to be coming from the right fork leg. Can someone shed a little more light on this. | ||

The clunk noise in mine is internal in the valving. I've took them apart and found no visible damage or problems. Its noticeable mostly when the bike is off and you push it over an uneven surface or pull up and down on the front. It seems to get louder with the compression and rebound adjusted up firmer. I switched to a synthetic fluid and it helped the sticky problem but it still clunks. The dealer found no problems but they did not take anything apart to check them. Good luck. | ||

Thanks for the reply. I was only guessing, but thats exactly what it sounded like to me. It's as if some piece of the internals is moving back and forth with fork movement. As long as it does not put me on the ground, I guess nobody else is worried either. | ||

just wanted to put my grain in. I also have that clunk noise on my front forks. But mine only happens when i use the front brakes and at low speeds.Im starting to think its going to be something with the front brake system. Im installing new brake because i need them and ill see what happens to the clunking noise. | ||

I wouldn't be surprised if their are a few different noises coming from the front of these bikes. My noise was there when the tire and brake were removed and the suspension was compressed. | ||

You guys really need to validate the steer head bearings are properly torqued first. This did solve the problem for some. Once you know it's not the steering head, then start looking for the problem else where. | ||

I second that plus my 25R just got 09 forks because of the same problem. The clunk was loud enough that it sounded like I was going to loose the right fork. It was replaced under warrantee. | ||

I had my suspension rebuilt at 30k miles. Between new fork springs, valves and oil AND retorquing the steering head, the clunk is gone. Can't tell you which one for sure, but I am very much of the opinion it was the steering head bearings. | ||

30K miles... absolutely amazing JDugger! Congrats! Why the new springs and new valves? Old ones worn out or upgraded versions? Did you do the work yourself? Im about to do the front fork service myself and any pointers that you may have would be helpful. Thanks, Ray | ||

clunk from forks could be metal spacer inside fork missing rubber bushing seen them come right from factory like that | ||

Does anyone know of a cut a way view of the fork I can look at? I might be able to figure something out without taking it apart. | ||

the noise appears to be coming from the right fork leg. I've had clunks on my Uly which were ultimately traced to the brake rotor. That would be consistent with it coming from the right side. The rotors on these bikes "float." When the rotor hits the stops, it makes a noise. The noise will stop when enough brake dust builds up in the rotor mounting slots and cushions the impact. It will come back if you clean the front wheel well. | ||

Not trying to argue about the brake noise, but it seems to me that the ZTL design would eliminate the normal play in the rotor with the use of the spacer between the rotor and bolt.  Labeled as 70 | ||

i went to get tires on my buell and the guys at supernation in Orange County CA. told me that the front axle was tooooo tight. they finally got it off with a 400lbs pnemautic gun. That got rid of my front clunk noise. So from the dealer they really over tightened my front axle assembly! | ||

> Why the new springs and new valves? Old ones worn out or upgraded versions? Did you do the work yourself? I did not do the work myself. I took the bike to Piper Performance in Fort Worth, TX for the rebuild. At 30k miles, frankly the suspension was just worn out. I decided to have forks and shock rebuilt completely with new springs, race tech valves and better fluids than stock. WHAT A DIFFERENCE! The suspension is not only firmer, but also more compliant and gives me more confidence. | ||

I have an 09 CR and have a minor clunk when I compress the front end. HMMMMMM didnt really think anything of it. Maybe I should do a little investigating. |
