I have the same issue - could use some help. My carburetors starting dripping at the track day last month, just out of the blue. Didn't pass inspection of course, so it sat all weekend. We thought it could have been the float valves, so tore them down for inspection, but they were working fine.
I ordered all new float valve carb kits the following week, installed new kits, cleaned everything up and still dripping like crazy. I took the carbs off again and did a more thorough inspection - took out all the jets and noticed the pilots were dirty (should have done that the first time). Replaced those with a set of brand new ones that I had. All the rest were good, but I went through everything with carb cleaner anyway. Buttoned up everything and still the same results...overflowing gas again...argh!
No gas flows when petcock is in ON position unless bike is running, otherwise not sure if I have a petcock problem?

Any thoughts appreciated.
