    float height question

    hi guys,

    when measuring float height with the "carbs off upside down method", the floats seem to "preload" the needle valve spring, this is the height i measure, correct? thanks!!

    The floats should be touching the springs, but the springs should be stiff enough to not sag a measureable amount. If the springs do get compressed, tilt the carbs up at an angle so the weight of the float does not compress the spring and measure again.

        My OE needles sag a little on my VM carb 550. Tips look go so they stayed in. No problems so far...

          I posted about 10 days ago regarding the exact same thing. I've never noticed it with OEM needle valves but it was very apparent with the after-market ones that came on my GS1100.

          Brian instructed me to order OEM needle valves....and I did!:-D (I wish the damn things weren't so expensive!!)

              I just took a quick look but I think the OEM number is 13370-18111. If you shop around, you can find 4 of them for about $100. It's about the most expensive carb part you'll likely ever buy but it is important and will likely not wear out if you care for the carbs properly.

              I don't know why they don't show up on Bike Bandit but their schematics are terrible and you can find better prices.
