I would be worried about why the clutch fluid was low, and sounds like you are possibly hearing "clutch chudder" but it's well documented and harmless.

Thanks for the reply big b i am stripping down the slave cylinder tomorrow to rebuild with new seals hoping this is the problem with the oil level will look through the threads about the chudder is that an easy fix ?

I highly doubt you are in need of a rebuild "rare for clutch slave seal failures", likely you have too much lube build up around the slave area, the push rod shaft will cause the push rod seal to leak oil, but if you are actually losing clutch fluid you should easily be able to tell. But crud getting into the slave cylinder is possible, but once again that is a bit rare. And yes there is a fix for the "idle hammer", I meant that and not clutch chudder. Terry Hinkle "Realshelby" is a member here and quite the machinist and brilliant problem solver.

Not so in my case. On my fourth or fifth now. It's not a good design for an "ADV" bike. All it takes is for one little piece of grit to get near the seal and its days are numbered. When you ride in the wet and grime, invariably, it finds its way in.

Almost certainly, if he's losing clutch fluid, the slave seal is the culprit.

I did have a leak on my 06 1000 and replaced the seal, yet another reason why I don't miss owning a 1000. My 650 XT has been through far far far worse than either of my previous 1000's, it just takes the punishment and keeps begging for more. Yeah the Vee's has a bad design for sure, most hydraulic slaves are more/better suited to shaft drives than chain drive bikes, but there are plenty of chain drive ADV machines with hydraulic slaves which have next to zero issues.

Have yet to hear the term "scoring noise" here so I am still a bit confused by that. LOL

If you do a search on here you will find some of us have made covers for the push rod to keep the crud off and save the seal.

Now while you have it apart would be a good time to make one and fit it.

I used a very light spring with some heat shrink over the spring, be warned the motor seal can be easily pushed back into the motor so something light is required as a cover.

Yup appears to be the "idle hammer"......annoying but harmless, and it's only a 1000 Vee phenomena.
