[Brogins]

Sorry Guys I was not online for a while.
My 999 is a std 999 2005..not S or R.
This morning I called Daytona and they told me is the first time they are advised of this kind of problem, especially on new bikes. They didn't give me any indication on the phone as the best thing to do was to bring the bike in. On the phone they indicated that can just be dirt in the calipers (???) . I have provisionaly scheduled the service in a week time, but I am keen to take everything down and check by myself.
I just cleaned the bike tonight and I may pop tomorrow to a Duc dealer (the closer I have is in Reading.. I think Pegasus..dou you guys know if is OK??) ..or I am taking the caliper down and the pads.. As with this weather is a shame to have the bike in the garage (still I agree twinfan that is not the case to use it if I don't get a solution to this issue..) . I am still thinking is not that serious..but it is really odd. Again, I am sure at this point that the noise and the difficulty in turning the front wheel on the stand is coming from the brake pads that are touching the discs, not the bearings...

I agree with your diagnosis Brogins, I think the pads/callipers are at fault. Let us know how you get on!

[Brogins]

Took everything down today - wheel, shims, calipers, pads....
Cleaned everything well, and the calipers yes were full of crap.
Reassembled everything right using the right procedure and the right torque values.
Well, the bearings are definetly fine.
The Pads are still with life left.
The brakes are working properly, but still after everything was cleaned, greased and properly reassembled, the pads are sticking a little bit on the discs. Now is better that the other day and I guess a little bit the pads/discs are touching anyway ... Of course with no calipers the wheel is turning like a bycycle wheel, perfect, but with calipers and pads on is a different story.... Just for curiousity, with the bike on the front stand, with one hand spin no big effort, how many revolution can the wheel do?

It should do at least 5 I think, if not more?

I dont think so, I think the light drag from the pads will stop it before one!

on my 999 I can count to about 5 seconds before it stops.

Mine has developed a shudder recently, we got the front wheel up today and think we have found the problem, left fork 2 rings showing, right leg 3 rings showing, eeeek, how can that happen ??

Beeb thinkiking about this, it'll affect the springs inside fork, they'll be unequal tensions, the sliders will self adjust to keep axle in line. If you ever bottomed them one side would take all of load before the other. Even so it need sorting and might as well clean calipers and discs while we are on and try and find whats hppening with the shudder, my best guess would be warped discs. it'll be worth dropping brake fluid out as well its meant to be done every 2 years even if not used.

You mean two lines for left fork and 3 lines for right fork above the triple clamp?

yes, exactly that, DCR has never altered it so its been like that since build and pdi.

Oh my..... the bike and especially the front end should feel like crap, huh?
