    difference between cv and bs carb slides?

    My buddy royally ****ed up one of the slides on his xv535.(plastic slides) It's a 34mm mikuni I think a bds. I know the carb is way different since it sits sideways, but could I use the slides off of say a gs1100? You know assuming I use his needles and springs etc; or are they too different? Zuki, carbs are way cheaper than actual virago ones, I can barely find a set for under $200

    It is doubtful you could interchange and have anything work. Slides have too many variables. Diameter, length, locating channel groove, cutaway, needle height, vacuum holes, diaphragm design, and more.

      Just popped up the 87 fiche...since we dont know what year your buddies bike is...and they are still available for 99 and change. Item #7.

      Shop online for OEM Carburetor parts that fit your 1987 Yamaha VIRAGO 535 (XV535T), search all our OEM Parts or call at 800-964-1882

      I would rather trust my bike to a "QUACK" that KNOWS how to fix it rather than a book worm that THINKS HE KNOWS how to fix it.

        First of all, it would be helpful to understand the terminology.

        "CV" is a type of carb, it stands for "Constant Velocity", which is achieved by using the slide as a variable venturi.

        "BS" is a model name for one model of carb made by Mikuni.''

        They are somewhat similar, but not interchangeable. For example, all (Mikuni) BS carbs are "CV" carbs, but not all CV carbs are "BS" carbs, as they might be made by Kehin, Dell Orto, SU or one of MANY others.

        Good luck in your quest to keep costs down, but sometimes you just have to suck it up and pay the price.

              Yes, Solex is a company name. Much like Mikuni, Kehin, SU and all the others.

                Geez didn't realize I had so many replies. Bike is an 87. He ended up gluing it back together with super glue... (don't look at me) that's held up so far. Diaphragms are still a problem but I found a company that makes em.
