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.
In order to know more....precisely WHERE were they dripping from?

If vent tube, that would indicate a runaway float valve issue as the vent is WAY above correct working fuel level.

If some other source...???? Dunno...gotta be more specific.

A bench wet test would reveal. If needed, I stand at the ready.
