Sounds like you have most bases covered:

Did the gas cap vent mod.

Used 5/16 fuel line.
Used 3/8 fuel inline filter (removed element for testing).
Drained tank and cleaned petcock.
Removed and cleaned carb twice.
Verified I used 2.5 Needle and Seat (checked stamp on side of seat).
Removed plastic filter in carb inlet.
Reverified float setting.


Can't think of much more. What do you have for a main jet.

If you unhook the fuel line at the carb, the fuel rushes out, right?

I re-check my float level and, without changing anything else, set it a bit higher and test.

By the way, can anyone tell me what should be hooked to the circled item in this picture. There was a piece of vac hose on it, but it was just open to air. The local Yamaha dealer scratched their head and said that they think it is an open air vent. The dealer manual shows it hooking up to a device I donot have (apparently California specific).

Good dealer. You are correct. It's open to the air.
