I've got a 98 YZ400F that I started to have an intermittent clunking after i rode it last. Asked some questions and people said to check the keyways and balancer. I have the bike stripped to the point of having all the outside covers off and getting ready to pull the clutch basket after I get the tool. I have found nothing at the bottom of the case but I did find chunks stuck in the gear attacked to the back of the clutch basket and a small pile of chunks in the void behind the cylinder and clutch at the top of the case. The basket seems to have a lot of play and I'm not sure what is normal. Guess I'll find out after that basket comes out. Any thoughts on other pieces that are aluminum on that side. I can only think of the clutch parts. And there was no chunks in the oil filter or oil after drained. Thanks.
