this is out of my league. Get some knowledgeable second opinions. Post these pics on DRRiders and get mxrob and gangs two cents and maybe thumper talk. If everybody agrees it's ok don't worry about it. otherwise we'll find a spare. Looks like we could get one, put needle bearings/seals in it - and for a $100 or so and be good as new. Don't you have like 50k miles on that bike anyway?
