I have heard that as well.....It has something to do with the crank sliding. When you push in the clutch it has to slide the crank back into place (that's why it is mushy at first, you aren't doing anything to disengage the clutch until the crank is back in place). Please feel free to correct me if I'm not explaining that correctly. You or your mechanic can always check to see if there is play in the crank. If I remember correctly GSXracer said that there should be a small amount of play. I believe he gave the tolerance....you should be able to search for the post.
