Easy Fix?

DO YOU KNOW THAT WEB-SITE THAT GUY HAS . hIS SITE IS AWSOME. iT HAS ALOT OF REPAIR ITEMS ABOUT HIS s600? I BELIEVE HIS SITE HAS ABLACK A S600 ON IT

If you're referring to me, Thanks!

Although this article is for the rear duovalve assembly, the front one functions the same. Since I am fanatical about trying to repair things not really worth repairing, I would recommend you make sure the duovalve is really the problem, and then buy the assembly. I've seen it for around $250.
