I have TT Keihin FCR 39 mm carb (kit bought from TT) on my 2008 DRZ400SM. Gas is coming from the drain hose at the bottom of the bowl when parked or riding. I doubled checked to make sure the drain screw was tight and it was. I loosened it all the way, and then tightened it again - problem still exists. I have read the floater might be stuck, tapped on the float bowl with the plastic handle of a screw driver in an attempt to free the floater if it was stuck – no success, the leak is still there. It is not flowing heavily, but overnight it drips very slowly, and fills about 2 inches of a small water bottle. Does anyone know if this is covered by TT’s warranty. I bought it brand new from TT few years ago so it might not be... Or any suggestions on how to fix this issue – my garage smells like gas Thanks!
