I was recently cleaning the exhaust valves in my 2004 pro x 600 and noticed one bellow was loose, I noticed the washer was loose and some metal filings.I went to loosen the nut off the valve and snap! The threaded end broke off. I’m thinking this was loose for awhile causing that washer to wear on the valve causing it to weaken? Regardless I need a new valve and probably a nut and washer. But, I can’t find one online to buy. Anyone have any idea what website to check? Or does anyone have a pro-x parts sled? Also, would blue loctite be a good idea in the future? Thanks.
