After sitting a bit I am getting quite a bit of faintly gassy smelling liquid in the air box.
Cleaned it up, started up, runs fine and no leaking.
Sit a bit and more liquid.
What's could be up?

gas smell
Is it definitely gas, or could it be oil?
It's possible that your piston rings aren't set. Or they could be starting to fail. This would allow oil to come up the cylinder wall, into the top end where it pushes out that tube that ties into your air box.

Re: gas smell
Smells gassy but not as strong as might be expected and is thinner than oil, but oddly colored yellow. Buddy puss.PIStaker wrote:Is it definitely gas, or could it be oil?

I'm guessing the fuel petcock is vacuum operated and maybe it's seeping when it sits. But when it runs it's bone dry in the tubes connecting to the air box.
Just changed the oil and it was not diluted with gas, so I'm thinking the float isn't stuck high as that usually ends up with gas in the crankcase.
Bike hasn't used oil and only 1600 miles on the clock.

Could be two types of leaks. There could be a leak in the vaccum tap diaphragm, which would allow fuel to run down into the manifold. The other could be a leak from the float needle in the crab bowl, and it's wicking up the fuel needle into the Carb venturi
At what point does a hobby become an addiction? I'm uncertain, but after the twelfth scooter, it sorta feels like the latter...

Correct. It has two lines going to it. The smaller one connects the tap to the intake manifold and transfers engine manifold vacuum to suck the tap diaphragm down and let fuel flow. The larger one connects to the carburetor and feeds fuel to the float bowl.Snap wrote:Where is that?az_slynch wrote:could be a leak in the vaccum tap diaphragm
AKA vaccum fuel petcock attached under the tank?
