fuel overflow
I ha a 98 fatboy with a mikuni hsr42 carb and a manual petcock. Man gas is flowing out the overflow tube. first it starts as a drip the flows pretty good. it even dripps sometimes when its running. How hard is it to adjust the float and can you do it with it on the bike? I am aslo curious how you test the vapor valve.
Thanks Wils

RE: fuel overflow
You`ve probably have a chunk of crud stuck under your needle and seat.Once in a great while my s&s will drip after the bike is shut off.Usually if I just tap near the side of the carb with a screwdriver handle it clears and the flow stops.It probably wouldn`t hurt to pull the base off the carb and give it a check and quick blow out from the compressor.Toby

I had a float with a pin hole in it and it would fill up with fuel, become too heavy to function correctly and wind up dripping fuel out the overflow. The devil was finding it because as you take the carb base off the CV the float would empty and appear NORMAL. Immerse the float in fuel once you remove it is the only way I was able to catch it filling. Sneaky little bastard float.
