I am looking for a replacement petcock for my 85 xj700. Are they hard to come by, or are there any aftermarket ones available? Any suggestions are appreciated.
you can try ebay, your local motorcycle place, were i go in louisville they buy, sell, and have scrape parts for most bikes and they have all the aftermarket avialable. if you can't find them that way you can try online stores.
Motorcycle carbs has a manual replacement for the vacuume unit,
http://www.motorcyclecarbs.com/manual_petc...cement_kits.htmor, K & L sells a rebuild kit that will work (I think!) for about thirty bucks.
check this site out to see what the kit looks like.
