[QUOTE="Fred W, post: 1417258, member: 3828"] If the bike is on the centerstand in the photo, that would mean they are fully extended. The discolored area would normally not see the fork seal very often during operation, but it would see the lower bushing a lot. My guess would be that is some of the Teflon coating that has worn off the bushing and deposited on the inner tube somehow. May be due to previously mentioned fork misalignment. You also mentioned that someone recently changed a fork seal on that fork leg. I wonder if they heated the outer (upper) fork leg to facilitate removing the seal. If they did, and they were over zealous with the heat gun they may have partially melted that Teflon coating? Not the end of the world if you can polish it off the inner legs surface. Try using a little metal polish on a clean rag and see if the shmootz will come off with that light abrasive. May as well also loosen, bounce and retorque the lower pinch bolts on that fork leg just to cover all the bases. As you loosen the pinch bolts watch to see if the leg springs outward on the axle shaft. If it does youll have your smoking gun. [/QUOTE]
