i just bought the seals from Dan at motoxotica give him a call he pretty much has everything also i think that BOSS is closer check him out he seems to be on top of things as well
top and bottom bushes
seals
check that nothing can get past the dust caps of any size. if it can = renew
check all shims on the edge of your vernier and if you can see the workshop lights underneath then = renew
run jizer down the face of the chrome = remove pits
rubber o rings are easy to replace.
