    gs400s carbs

    I picked up a 84 gs400s that has sat for several years. On pulling the carbs I find that there is no piston spring in either carb. Is this normal for this bike?

    Can't say for sure, but I have always seen springs in there. The 400S was not imported to the US, so I don't have any diagrams available.

    What little corner of the world do you call "home"?

      @ atrent...I have an 81 450s and upon ripping down the carbs (has only 2) I found that one had the spring and 1 did not. That that was very odd. The PO included a tech shop binder that looks like it was well used back in the day and the carb rebuild section shows that the carbs do in fact have the springs.. hope this helps

      have you been able to get it running? I cant seem to get mine going.

        AFAIK, all CV carbs use the springs, it returns the slide to the down position.

          Not all Koolaid. The ones on my 83 gs550 don't and the carbs I did for my bud's kawi 750 didn't either. Both Mikuni BS type carbs. In stead of the spring they use some of the air being "drawn" into the mouth of the carb to push the slides down.

              if it were supposed to have the spring wouldnt it have the indentation in the cap that keeps it in place...and if it wasnt supposed to shouldnt it not have that indentation?...just a thought
