GL 1100 Flooding?

Post by S.A.Stuart » Mon Mar 31, 2014 1:41 pm



I am new to this game.My GL 1100 would appear to be flooding.On starting she runs o.k. for a minute or two then starts to misfire.If I turn the fuel stopcock off,she,after another minute or so,cleans up and runs beautifully before dying.I have installed new(pirate)needles and set the floats as low as possible(24mm).No change.I cannot see any problem in the seats.Do they wear at the sealing edge?If so is there anything I can do?Do the floats lose their bouyancy with age?Or am I barking up the wrong tree?I live in South Africa and carb kits are not that easy to get hold of.Any advice appreciated.S.A.Stuart

Not sure what the spec is for the floats but am sure you do not deviate to mask another problem.

A common leak point which will flood carbs/run rich is the plenum halves below air cleaner. Look at the plenum floor for fuel pooling with engine running for seal failure.

d rings between the carbs and plenum, plenum gasket and leaky float seats/needles..look into the plenum..use a flashlight watch for source of extra gas..if it will flood while not running put paper int he plenum that will show you the source..for sure

Nope-dry as a bone in the plenum.-Can it be anything else beside the needle/seat?S.A.Stuart

This is it for leaks from the carbs, note... leaks from float needles can be bad seat, bad needle or floats set incorrectly


d rings between the carbs and plenum, plenum gasket and leaky float seats/needles which comes up through the jets and all will show in the plenum..but the bike may need to be running with pump pressure to get the flooding.

You could try a alternate fuel source 6' above the carbs hooked directly to the #3 carb port..9the 6' gives about the same pressure as when the pump is running) paper in the plenum will show leak if any..there shouldn't be any gas coming through if the bike isn't running..

like the pic but much higher
