i found a lime green gasoline in my carbs????? normal///////?????? never seen that color gas before

 

not sure what old corroded and stale gasoline will look like.

Is your air box clean? if your air box has green stuff in it, id be worried. Other wise just clean those carbs really well.

 

air filter was dirty...real dirty

 

That happens.

I wouldn't worry about it at this point. Clean the carbs (properly) and see how it runs.

 

where does the auto fuel vacuum tube hoook up too??

 

you mean the vacuum line coming off the #1 carb? It connects to the petcock on the F2.

thanks for the lesson !
question?
having mine done as i post they will be ready bye sat
he did text and say carbs may run a little lean due to my yoshimura pipe
how do i adjust for that?
after there on and running my abox is stock as well

thanks

 

i downloaded a f2 manual off the net and it shows three holes under tank.. a fuel tube goes in the petcock, fuel tank drain tube, and fuel tank vent tube..so that line from carb 1...does it go to the gold piece right up under it????????

 

Do you have a jet kit installed? You can't do much tweaking otherwise. You could shim your needles up a tiny bit and turn out your idle screws. However I doubt you will need to do any tweaking for just a pipe. Ride it first and find out.

 

There are 2 holes on your petcock. one fat one (fuel) and one smaller one (vacuum). The 2 lines that come from the bottom of the gas tank aren't a big deal. They just lead to the ground.
