This is a spinoff question related to springs and oil improvements in the stock forks
I'v noticed a clunk in the Stock forks on full extension on a s2r 06; does eveone have this noise? is the rebound damping damaged? .... I'v read various posts; but don't know enough about forks to put my finger on the problem; or is the clunk normal?
ooowww this is a popular one [popcorn]; I'll try bumping once; .... is anyone else clunking?
Same thing happened to my equally crappy 2003 M800 Marzocchis. Here's the thread: http://ducatimonsterforum.org/index.php?topic=19632.0 (http://ducatimonsterforum.org/index.php?topic=19632.0) Based on the responses, I don't think the noise is typical, but you and I beat the odds [bang]
I elected to not become a fork-internals specialist right now and bought (first) a set of replacement Marzocchis on ebay for pretty cheap. They'll get me around until I assemble everything needed to install SBK adjustable Showas I just acquired.
BTW, the replacement Marzocchis behaved no differently than my clunking Marzocchis, so the noise doesn't seem to correlate with malfunction. Made me nervous, though.
Loose steering head bearings maybe? I had a 'clunk' once in a customers '05 620 that was loose head bearings.
But of all the noises on a bike you can type about on an intarwebz forum, 'clunk' is a hard one to diagnose.
steering head bearings - thats what i thought it was and it the first thing I checked; bearings seem to be solid with the ft break locked and a finger on the stearing tube and top tripple; no play, no wiggles ...

"mechanical clunk", "click" or "clack"; like a bushing is missing (or %$#%^$ some-thing-a-maggiy!) on the full extention of the rebound ... ya! hard to describe and diagnose.

.... ha! I remember reading your post and it seemed to be the same problem; have you dismantled the forks? let me know what you find!
Nope. As I said, I chose not to work on these crappy Marzocchi forks. Bought temporary replacements on ebay to get by until the SBK Showas can be installed.
Someday maybe I'll take them apart... or not.
If the Marzocchi's have dual-rate springs, maybe the soft rate is coil-binding before it reaches the stiffer rate.
