Zu dieser Problematik gibt es grade einen guten Beitrag mit Bildern auf MaxZuki: Need some clutch answers - um ihn lesen zu können, musst Du aber registrierter User sein.
Ok here is my .02 worth
1. Replace the clutch disks and use the factory type friction disks. On the steel disks it won't matter if you use factory or aftermarket. (Kevlar friction disks have a habit of sticking and dragging, this causes clutch creep and hard shifting) I like to use the 10% stronger aftermarket springs too.
2. Replace the the spacer that the basket rides on.
3. Replace both thrust washers (I will just bet your washers will show signs of wear).
4. Take the new spacer and thrust washer and rig them up with a plain old harware store bolt, nut and flat washers (as in the pics below) and check how much clearance you have. I like to see about .007 to .010 clearance, but this is not an exact science. I like to check this before I start taking any material off, this way you know where you are at. When you rig this up the first time you will probably have virtualy no clearance, thus the reason for taking off some metal. I take it off of the back side of the gear on the back of the basket, mainly becuase I don't have the resources to do it any other way.
5. With the proper end clearance torque the hub nut to 40ft.Lbs. And then check to make sure that there is still some end play on the basket, by pulling out and pushing in on the basket. the center hub should also be able to turn freely.
6. While you have the clutch apart (before assembly), use a smooth mill file and clean up the grooves in the fingers on the clutch basket. These marks are normal wear but can be smoothed up a bit, just don't go nuts with the file, just smooth things up a little.
Below are some pis to help you along, I even include one of the homemaid tool that will allow you to tighten up your hub nut, that along with a penny between the primary gear on the crankshaft and the ring gear on the clutch basket. NOTE - NEVER EVER put a penny between the oil pump gear and the primary gear on the crankshaft, or the oil pump gear WILL BREAK!

This should make for a smooth working clutch that is very easy to find nuetral, even once the bike is up to operating temperatures. I hope this helps you out a little bit.![]()

Ich hatte ja auch die Probleme. Nach einer kompletten Kupplung Anlaufscheiben und Beläge ist es jetzt weg.
