Clunk in forks : Honda CBR 1000RR Motorcycle Forums: 1000RR.net

never was able to hear this cluck when riding due to engine noise. Was moving bike in garage and grabbed front brake harder that i normally do, and heard a clunck. Traced it down to either steering stem lose or internal in for. Check the steering stem torque and it was tight, got about a 45* turn out of it, used beam torque wrench and it was at 17ish and now at factory spec of 20 ftlbs. So i rechecked and its in the right fork, throttle side. Ive never rebuilt the forks on this bike, but ive rebuild many of similar style. But ive never had to rebuild due to noise. It was either spring changes, seals, fluid changes or bushings. there is no play in the fork to indicate a bushing and seals are not leaking. It only makes the noise on compression and it isn't normal to me. I tried adjusting spring preload to see if something was broke springrate did change so i dont know if anything is loose. Bikes an 07 with 6000 miles; i ride hard but rarely pull the front up. any thoughts.

No expert.... I've had my forks down a couple times for service. I'd look at the bolt at the bottom of the fork for being tight and the bushings being worn after that. Not likely at 6000 miles.

there is no play in the forks between the outter tube and the inner tube so id say bushings are good. Didnt thin about the retaining bolt at the bottom.

thanks

dont know if you recently got the forks rebuilt or anything but if the person reworking them put the springs in upside down it'll make this weird clicking sound.

No they are as is from the factory. I haven't even changes the oil yet. I don't remember ever hearing this sound when the front end compresses

Rebounds possibly bent?

If you are using the front brake and compressing don't think you could rule out the clunk not coming from the front brakes. Rotor float or something of the like clunking.

I ruled out the stem and everything else. I narrowed it down to the right fork

See rotors as culprits first

Ever see any fluid anywhere? I had one do that due to low fork oil.
