check the needle valve attached to the float (signs of wear, dirt). If that and the bowl are clean, the float level might be too high - GENTLY press it down a bit.
I have had to adjust the float bown 2 or 3 times over the last couple of years on my $&$ E - itwas dumping fuel while the bike was just sitting there shut off (fule shut off) - has only happened once this year
hope this helps
