After having this same 610 for 14 years and not having much trouble then selling it after getting my S 250 I'm getting it back for less then 1/3 I sold it for!! WOO HOO!! The left rear axle seal is leaking and my local dealer whats over $800 plus parts so this is a DIY project. Just a little history before I sold this 610 3 years ago I rebuilt all the cylinders,starter,alt,battery,seat and all the tubes.. If someone has done this and would like to help me out that would be great or maybe let me know where to find info on this subject..
