    CV Carb throttle valve adjustment

    From memory you insert a feeler gauge or penny or something under the valve to leave a small gap when setting these.

    Presumably you do it with the idle adjust stop set a particular way as well.

    Mine are out of sync (1100G). Can someone tell me what that measurement /process is, I don't see it in the manual. I know they should all match number 3.

    Thanks!

      You don't need to measure, just use your eyeball holding the carbs up to a light so you can see under the butterflies.

      - tweak the center adjuster and make 2-3 equal.
      - then tweak 1 and 4 to be level with 2-3. It doesn't matter what order.

      Be sure you can get all the butterfly's open by using the main throttle set knob.

      That's about it.

      To measure is to know.

        Thanks Ed, that's about what I remembered but I wasn't sure if there was a set figure.

        Now I need to sort out why it doesn't return back to fully closed when connected up on the bike. Not enough adjustment in the cable stops at either end, little bizarre to be honest!

        From another thread as this is prob a better place for it... :

        Does anyone have a measure of the amount of cable pull for the CV carbs?

        I'm having the same issue with what I believe is a stock cable. Weird because I believe the cable has worked on the same bike before!

        I measured the amount of free cable (inner sticking out of the outer) at 47mm. I have one from the older carbs which I can measure... but maybe also a GS750ES which was also a CV carb. I'm wondering with mine if maybe the throttle tube is not stock but then again that was on the bike too...

          Do you have the cable nipple in the correct hole on the twist grip, mine has two holes where the nipple fits.

            As it turns out I didn't and it did! I'd missed that. Not sure if it's a stock one or aftermarket. Don't remember my other having a second hole. More haste less speed required I guess!

            All sorted now.

            For anyone interested it seems that the proper cable pull is approx 70mm.
