I have a 95 Suzuki Bandit 250, I can't get it to start, it will start sometimes but only run for maybe 3 seconds before stalling. I have checked the carbys, the sparkplugs, the airfilter, changed the battery and drained the fuel and replaced with fresh 95. Anyone have any ideas!

Spark plug lead!

They seem ok, they have a spark. I tested it by putting a screw driver up into it keeping it near the motor and pushing the start button, is that the right way to test!

Fuel filter possibly blocked so not getting fuel. Be wary, your bike could have a filter in the fuel tap or a gause on the Carb inlet. Try removing the fuel line from the Carb and seeing how much fuel flows out

Checked the filter, I removed the tank and the only way I could get fuel out was sucking on the vacum hose and fuel would dribble out

Get it going with CRC engine start in the carbies.if it stops when you stop spraying, it's starving for fuel. Could be a faulty/blocked or corroded fuel tap!

Thats a good point, how would I check the fuel tap!

So sounds like your fuel tap has a vac cut off, same as my honda.
My first port of call would be. making sure that the engine is drawing vacuum down the hose.
Check that the vacuum port isn't blocked (and that you're plugging the hose in the right place), and check that the vac hose isn't getting kinked.
Edit to add: you might try manually drawing a vacuum (suck on it) and while doing so pinch the hose closed (vice grips) to keep the vacuum drawn this should make sure fuel is always flowing from tank, then try running it, if it works, you know what the problem is.

Is there a cut out on your side stand
could be water in fuel

I manually drew a vacuum and pinched the hose with pliers and the fuel kept flowing so does this mean the engine might not have enough vacuum!

open the fuel cap.might be as simple s the breather,wen fuel leves the tank it has to be replace by air,although it would probably run a little longer than 3 seconds.worth a crack though Gav

After trying to start it check the plugs to see if they are wet.I had the same prob with my wifes one and even tho there was spark there it just wasnt doing the job.After chucking new plugs at it away it went.Just a shame they run the $20ish each plugs instead of a $6 job.

Ok I will give it a go, the spark on the plugs is pretty average anyway and I did notice they were slightly wet. Did you need to replace all four plugs!

Yes i did replace them all,As for needing to it was much easier to just replace them all as if one or two were getting sick the others wouldnt be far from it either
