Nice bike for only 900! you can upload your pics with "insert image"
as it stands for now, got a belly pan to have sprayed and fitted, new rear brakes, paint swinging arm gloss black to match the frame, and get rid of that fugly rusty horn for a nice steibel nautilus :)considering making a solo seat cowl out of fibreglass myself we'll see how that goes Details20190323 17520020190323 175200
Save the small o ring that goes between the two halves of the caliper The new seal kit won't have that. Sanding the piston could give you problems in the future. If you sand away the protective coating it might cause the piston to rust more
Powerhouse UK do a kit which includes the seals if you slip the caliper like you have. https://www.ebay.co.uk/itm/Yamaha-FZS600-FZS-600-Fazer-rear-brake-caliper-seal-repair-kit-1998-1999-2000-/151066754467?hash=item232c47bda3
