    Hi people... I have a clutch assembly in pieces that I'd like to reuse. I know they should be marked on strip down to keep the balance in order but this one failed to get the scribe treatment. I'm wondering how important the marking process is and if anyone has had experience with the same... I am guessing that new clutch kits don't come alignment marked so I'm thinking/hoping that maybe it's not too critical???... What think ye?....

    Common problem. All you can do is put it together and pray. It'll probably work just fine. Clean the dust off, there might be original marks?

    Would be nice if people told us what year/model they are working on but this time I guess the answer would be the same?

    I put mine together a few years ago with a collection of different old & new parts - I had no problems with vibration and I didn't have marks to go by.

    The answer wouldn't be the same. Pre '81 clutches never did have the balance marks brand new.

    Post '81 clutch plates still come marked. To use the marks correctly first you have to see if your flywheel still has the balance mark? Then you are suppose to separate the three marks 120 degrees. The problem with that is that there is only a small number ways the two clutch plates can be bolted onto the flywheel. Most of the time the closest you can get the three marks to 120 degrees apart isn't even close to 120 degrees apart. I have installed a LOT of those clutches in all the different R and K bike models and I don't think I have ever seen them remotely close to evenly spaced. Maybe once or twice? If you can't find the flywheel mark it doesn't matter anyway.

    I got curious one day and checked the balance on about seven sets of plates I had laying around. All of them balanced perfectly no matter where you had the marks.
