my brand new 2010kx500afx leaks fuel out of the carby bowl overflow hose while it is running and leaning over say 20 degrees at most,it does not miss a beat and is very annoying as i have looked at a few areas to fix it but cant,my float height is spot on 16mm,all the jets are tight and clear(stock jetting)the seat is sealing where the fuel comes in and shuts off at exactly 16mm,i was thinking of adjusting the float level to 18mm as this would fill the bowl fuel level up 2mm lower than it is,and further away from the top of the overflow tube,but have read somewhere that doing that could make it run lean as it would not get as much fuel in to the cylinder as compared with 16mm level and dont want to damage anything,has anyone experienced the same problem and what did they do to fix it..?..the valve on the tank fuel cap is working and not blocked..no airleaks that i can see..running out of areas to look..?..also the choke when put on whilst hot does not make the bike stall run crook or anything and im thinking that both of these problems could be caused by the same thing whatever that is..
