    since everyone is into the carb adjustments these days (or maybe I just notice it now that I'm doing it too!), I have a question.

    I put in a new jet kit to go with the new filter, and was trying to measure the float height last night. I have my calipers set to 4mm and removed the bowl and tilted the carbs so that the floats just rest on the needle. Measure it and it's spot on at 4mm. Just for giggles I go to confirm the measurement on the other side/chamber of the float (it's two "chambers" connected) and it's much lower. I can look at them side by side and see that one side of the float/chamber is lower than the other.

    I checked the other carb and it was the same way. one of the floats was right on the money the other side seemed like it was a bit different.

    did I have the carbs tilted or something, or has anyone seen the floats (in one carb) bent or something?

    too late to order new carb floats for this weekend, and it fired up nicely this morning but just curious to hear if anyone else has seen this or if I was doing something wrong...

    not my floats but just another ADV photo of the floats to show the two "chambers" where I was getting different readings...

    Split the difference and/or apply a little pressure/heat to bend them back.

    I have a theory that this is the result of ethanol and leaving the bike parked on the sidestand.

    They are made of plastic. It's a verb and a noun. They are never perfect. Just average them out.

    BTW, 4.0mm is a bit low.

    Yep, same thing here.. I adjusted the level to the side that was higher (closer to the fuel)

    This method will not tell you the float height, but fuel level. It may be useful to compare the settings of the two carbs. Maybe a bit long-winded.

    This is the correct way to measure float height:
