I know I can check the floats on the bike,  but the carbs are off right now.  Ive been searching for 2 hours for what to set them at as a starting point and can't find it.  My manual has been lost.  Can anyone point me in the right direction.   I know its 14mm but cant remember where to measure..

its on the main page under how to

hope this helps

I know how to check itwith the u-tube,  Im looking for a startingpoint when reassembling soI dont have to keep taking the bowls off and on

I have been taught to make them parallel with the gasket surface as a starting point, but I already know that this will be too shallow, so to make it easier for you set the floats so that they are 1/2 an inch (13mm, okay 12.5 technically) at their highest point above the gasket surface when the float needle just seats.

See if this old post (and the rest of the thread) helps.

Thanks guys,  I have to get new carbs as one of mine broke
