Clutch drag

Just when i thougt the bike was in a decent state another problem presented itself, so i have to bother you guys with another question. When pulling the clutch lever if the bike is cold and in gear the bike no longer is easy to push forward by hand. In neutral or once the bike warmed up the problem seems to be gone. So i read the forum and owner docs to see what was wrong with my bike and first replaced the o-ring of the Magura clutch and refilled and bleeded it. As this didn't solve my problem i now think the clutch itself might be the problem. From what i read there are 4 things which i could do:
-Replace basket (outer clutch hub?)
-Replace drum (inner clutch hub?)
-Replace plates and springs
-Change order of the plates

Which of the above things would be my best bet to solve the discribed problem? Or is it better to just replace all in once?

Is this something that suddenly occured or was it like this all the time? Sounds like cold oil drag and is (if within reason) fully normal. Of course if you are sure the clutch hydraulics are good and suspect that you have over heated the clutch you could inspect the plates to see if they are still flat. If nothing is wrong nothing helps. Regards.

Mine does this and i have just gotten used to it. as my local bike shop claimed all the 02/3 bikes do it???

Not sure if the clutch hydrolics are good, the clutch master also might have a problem. But i'm not sure how to check this.

Problem occurred suddenly after riding in muddy conditions. After i cleaned the bike i noticed the problem.

Surfdude,

Your problem is most likely caused by the steel clutch plates warping.

If you have to check it to solve your curiousity remove the clutch pack and lay the steel plates one by one on a flat surface and look all the way around the plate. Chances are you will find two spots that are not on the flat surface 180 degree's apart. This is a normal occurance when you "use" the clutch.

The first sign that you have warped the clutch plates even a little is a bit of a shrieking noise coming from the clutch when cold and you are just starting out, or sometimes when hot when you are slipping the clutch at just the right engine speed. This caused by the steel clutch plates jumping back and forth due the warpage, and I expect the sound itself is coming from the movement of the plates on the inner hub. The KTM's do the same thing but it's nothing really to worry about.

Just recently I had to replace mine as I had fried it when I went to Moab. Each steel plate had about 1-2mm of lift at two points on each plate 180 degree's apart. It had gotten so bad on mine that the bike had a hard time starting on the button when warm, and it gear.

The cold drag is pretty normal. If there is still a lot of drag when the bike is warm then it is time to replace probably just the steel plates. Check the fiber plates are still in spec, and do not show any chunking. You will be amazed at the difference in feel in the egagement when the bike is running. Either cold or hot, if the bike is in gear it will be noticeably harder to push around.

Changing the order of the plates more than likely will not help.

The only time you need to replace the inner hub is if it has significant grooving or wear on it from the steel plates. The grooves that form there keep the clutch pack from expanding properly and cause drag.

The clutch basket itself is steel and unless you break the ring gear or something severe like that, I kind of doubt that you would ever have to replace the basket due to wear from the fiber plates. As opposed to aluminum baskets on "other" brands of bikes that are made of aluminum that will get notches in them.

chamber....gawd help you...

daleO .... can't agree

check the steels for a purply discoulored area. if you don't find one then replace the clutch drum. 100% cure.

yes they all did it but some of us did something about it.

welsh people - i appeal to you all. don't. suffer. in. silence!!!!

I totally respect the advice you have given me Taffy and without your help Berg ownership would have been a much greater ordeal for me. With regards clutch drag with this previous thread, a lot of owners suffer with this problem and don' worry about it to much

its frustrating to have people undermine your answers from an armchair. having once had a 100% cure i want the word to spread but someone always comes along and says well i did this or that and then the message is lost!

I had the same thing with a FS650c, and to make matters easier, I have an FE650 that I used to easily swap parts with.

I switched entire hydraulic assemblies, from the lever all the way to the slave cyclinder, no help. The rod in the center, no help. All steel and friction clutch plates, no help. I did have a couple of hot spots on the steel plates but they were still true. The only thing that cured it for me was the inner clutch hub.

I also installed new washers that go underneaththe hub (those split ones) at the same time so it may have been those that cured it too. By the way, there was no "visual" wear on the clutch hub or washers.
Good luck.

and do you know what..... we'll have this same phucking argument in three months time.

see you all in three months then! same place. same time!

It's easy, pull the "clutch cover" and watch the pressure plate when you pull the clutch lever. If it raises and holds it's position, IE doesn't fall back down your hydraulics are okay.

Just pull the clutch pack and check the steel plates to begin with and make sure they are not warped on a known flat surface, and while you're at it check the fibers for warping as well. That will eliminate that as a problem and is very inexpensive, as opposed to just starting to throw parts at it.

Let us know what you find.

Hey Chamber,

Thanks for posting that link, I had forgotten that I had written that story about my 94.

Thanks guys, will check the clutch in a few weeks once i need to change the oil, so i can do all in once. I'll let you know what i find then.
