any advice would be handy

HAVING PROBS WITH MY K1 1000.WHEN THE BIKE IS FIRED UP EVERYTHING IS OK.WHEN REVED AND ALLOWED TO IDLE AFTER THE THING JUST DIES.OCCATIONALY WHEN RIDIND THE BIKE HARD WHEN COMING TO A HALT THE THING DIES ASWELL.HAVE CHANGED THE PLUGS.COULD DO WITH A NEW BATTERY.POWER COMMANDER FITTED BY PDQ.I COULD REALY DO WITH SOME ADVICE FROM ANYONE AS I HAVE A TRACKDAY AT BRANDS ON 18TH.WILL TAKE IT TO WEST LONDON SUZUKI ON MON SEE IF THEY WILL GIVE IT A DIAGNOSTIC TEST FOR ME::

I would check the idle-speed first, Mark. On some Suzuki’s, the idle speed can drop with time and produces results as you desribe. I’ve had this before, it confused the hell out of me as I thought how could the idle speed cause it to stall under power, but it did. The idle speed should be about 1300 rpm, I believe.

I’m not familiar with the K1, but if it’s like other Gixxers, it’ll be a small dial on the LHS by the airbox, accessible once the tank is lifted up on its hinge. Lift the tank and let the bike run, then when warm, set the idle speed by turning the dial, you’ll hear the revs climb as you do it. Your manual will explain it in more detail.

I know nothing!!

Yes if its cut outing while halting or just after running idle its def the idle rev thingy. I had this problem b4 to…was so annoying until i clocked on to what was going on. If u had ure bike serviced the mechanic some time reset it to start point.

Yes could be idle speed which should be around 1200rpm. Other than that, it may be over fueling when you shut off. This would also cause the problem of stalling when slowing at junctions etc. Get the throttle position sensor checked to make sure it is on the correct setting and then get the bike put on a gas analyser. The readings at idle should be about 2 to 3 % co and hydrocarbons (unburt fuel) should be well below 500ppm (part per million). Hydrocarbon level is very important. You can have a bike running at optimum co and the HC level can off the scale, a sure fire indicator that there is a spark or compression problem.

And so ends todays lesson, I thank yaw!

I had the same on my k4, that was the idle speed, very easy to adjust, refere to your handbook. But like jay said, lift the tank, and it’s on the left hand side, just adjust untill you reach about 11/1200.
