I'm looking at a Suzuki bandit 400 with about 30,000kms on it.

It starts and idles fine from cold, but once its warmed up it gets cranky and stalls - won't idle etc. It's only done about 1000km in the last 6 months.

Any ideas?

TIA,
Steve

Something simple as old fuel and spark plugs?

coil breaking down ? or sucking in air as things warm up an expand with heat ?

is it as simple as the idle set too low?

is it as simple as the idle set too low?Will check.

The bike has barely had a tank of gas through it in 6 months, so it might just be old gas and dirty plugs yet.

Ok my mate had a look at it, and its running REAL rich. It starts and idles fine, but any attempt to rev it and spouts grey fuel-rich exhaust smoke everywhere and it wont rev out. It's obviously got some fueling issue, or leaky fuel pump diaphragm or something.

Any further comments anyone?

Air filter, float levels etc. Give the carbs a good clean out/set up/synchronising

give the carbs a bash. Ok Ill rphrase that. Get some BP 98 in the tank.
Tap the side of the two outside carbs. sticky floats could be your problem.

Doesn't normally apply to bikes, as most people normally fill every time and often, but since it was sitting for 6 months could be applicable.
Have been told by a mechanic that fuel tanks should be kept topped up over winter, as cold weather can cause condensation on the inside of a tank, and lead to fuel blockages in the carbs.
Borrowed my mates car for a couple of weeks and was unlucky enough to have that happen. It was as simple as a jet blocked by water.
Idled fine, but as soon as you went to accelerate... splutter.
And this was warm sunny auckland too!

I went and had a look at it. The carbs have been stripped and cleaned, and its no better. The bike is scrappy and scruffy and I don't want it. 10 hours drive to go see a bike I dont want, ugh. Not amused.
