filling cyl with fuel

[Gsxrsam]

Is it a common prob for slabby to leak fuel into no1 cyl? 

 

[Duckndive]

Odds are any bike with a dodgy fuel tap / carb will leak fuel into No 1 if on side stand for any length of time

Diaphragm tap or non-diaphragm tap?

If it is a non-diaphragm tap,then you need to turn the tap off when you are not using the bike.

If it is a diaphragm tap,then rust(i had this happen) could be stopping the diaphragm from shutting off.Strip and clean. Also check your carbs,the float heights could be wrong or there is wear.

vacuum tap Del.

in my head it should not matter if tap on or not, as float needle should stop any fuel getting past.... slingy has never done it in 14 years..............

 

[KATANAMANGLER]

If the diaphragm on the tap is shot and seat of the needle valve is worn or the needle valve O ring is shot the fuel will work its way past while the bike is on its sidestand.

As katanamangler stated there are TWO problems simultaneously:  diaphragm tap AND float needles fooked.

And don't try starting it without removing plug No1 as you might suffer the hydrolic lock.

I had pingel fuel tap fail that caused bore wash and yet another rebuild when engine was quite fresh.

Taps can be complete pain and cause all sorts of problems. 

The stock suzuki tap is awful on tuned engine can starve it of fuel, I seen 5 hp improvement on one once just pressing on tap.
