zx6r stalls

Hi all,
I purchased a 04 ZX6R about 3 months ago. The bike is with the mechanic since then. The bike dies when coming to a stop and it happens just after pulling the clutch in.
The 636 is in an official kawasaki dealer but they are not finding the problem and they already checked and adjusted everyting.
Any one had something similar?

Thanks for your help!!

Does the bike try and hunt when stationary? Ie, does it try and increase revs only for them to drop straight away? If it does, I would be inclined to look for a vacuum leak. As Vacuum hose is relatively cheap, I would probably replace them as it can be difficult to isolate a leak.

Thank you for the reply rainbirdb.

When I turn it on from cold, the rpm are very irregular. After being hot it gets better. It keeps working unless I accelerate and cut the gas in a fast movement. In that case, when the revs come down the engine goes down. The bike is easy to start and it goes well all over the rev range. The problem is this down low rpm, that even increasing the idle to 1500 does not solve the problem. The mechanic told me that already checked the vacuum line but I will check that again.
Thanks.

What about a sensor? It sounds like it's having a hard time maintaining a fuel ratio.

Good call Chriscode. Failing Vac leaks I would look at TPS (Throttle Position Sensor). If you know anyone with a ZX6R try swapping yours over as they can be expensive to buy.

Hi guys, yes it should be something related with the fuel ratio. The new spark plugs are already dark. Not with oil, just dark.
The mechanic wanted to try parts from other bike but we dont know nobody with this same model.
The shop just sent the injectors to test if there is a leaking problem.
Thank you.

The shop should be able to test them in situ. Fire them up and if they produce a fine fan spray they are good, if they dribble they are bad. Brings back memories of testing diesel injectors when I was a lad. Now if you think you have a boring job, just recon injector needles and test them all day every day!!

If it happens every time when you pull in the clutch it may be time to inspect the clutch switch and wiring associated with that area. Sounds electrical to me.
So they have had it for 3 months and still cant tell you whats wrong? Have they even tested the throttle control sensor to see if its burnt out

when i first got my bike it had a dead spot around 8k rpms and would die when i pulled the clutch in it had a vacum in the wrong spot it was the vacum from the butter flys it was attached to the barometric pressure sensor and it would effect the air to fuel ratio

if i die at 150 tell em i was smile n and headed for living170

life around 160
