Raw gas blowing out exhaust

[Anonymous]

Can anyone tell me why gas is blowing out exhaust both sides.Bike starts and runs smokes badly with raw fuel blowing out exhaust.HELP

Well it certainly sounds like it's flooding, it could have c##p in the float bowl's keeping the float needles open.
If it's only just started doing this I would doubt it's the float hieht.

yup. Id pull the plugs to get an idea whether or not its just one cylinder or which cylinders are fouling, plugs should be wet and or black on the cylinders puking gas.

is this a bike you are bringing back from the dead, or one that you have been riding and just developed this problem?

Check vacuum petcock to make sure you're not pulling gas through the vacuum line. If this is a two cylinder it would be very rich on #2.

AH! that's the if , is it a two cylinder, is it a four , is it a Suzuki, is it a bike?
Fireman we are allways willing to help ,but a little info would be great!

I have no doubt it is running rich, but to spew raw gas is :? hmmmm freakish 8O . Especially on both sides 8O . Is one or more of the header pipes stone cold? If they are all hot or warm, any gas in the pipe would probably ignite 8O and you would shoot flames out the pipe or blow the pipe #-o , done it and seen it happen, lots of black smoke. It could be condensation which smells like gas because of a rich situation and it is blowing out the pipes. Also to spew gas you would also see an increase in your oil level #-o as some would leak past the rings as well as being blown out the exhaust.

You also could have a no-spark condition in a cylinder or two.
