air filter box/housing full of fuel

What he said. Check oil level and drain if full of fuel. Then take bike outside, remove tank, drain carbs, remove spark plugs, disconnect CDI so no stray sparks, stand back and then crank the engine over on the starter. It will immediately be obvious if any of your cylinders are full of fuel as this will be forced upwards in a jet out of the plug hole.

For this to happen you have to have the 2 problems at the same time, the fuel tap passing when engine not running, and one or more float valves not shutting off.

 

Do as dezza says above, then stick your carbs in a vice and rig up an auxiliary fuel supply, that will show you which float valve is passing, and try it again when they have been cleaned or replaced.

Then check fuel tap isn't on prime before fixing it..:tu

Yes it's a vacuum tap, no flow if the engines not running...

See you can get a repair kit..:tu

 

BUT the carb float valves must be passing as well or they would shut off and not flood the engine....:D

hi can you direct me to a repair kit,cheers raggy

At the very least you need to change the filter and drain all the oil in the sump and the cooler, is the cooler top or bottom fed??

Last time this happened I used some cheap oil to flush the system completely..:tu:tu

 

if the tap doesn't have Prime then its definitely passing so will need rebuilding..

gonna change oil filter and all the oil in the sump looks like its all gone/drained.as for the cooler its bottom fed should i disconnect the feeder pipes or do you think the oil would have drained when sump plug was removed,thanks again raggy(y)

DO NOT USE FULLY SYNTHETIC OIL - it causes more problems ....... mineral or semi synth only. Fully synth can kill the clutch in less than 50 - 100 miles!
