Only had my bike 3 weeks , love it, only problem, it stalls/cuts out every now and again at low revs. Seems to be soon after start up on a warm or cold motor, as if youve dropped the choke off too soon. today I did 7 miles on the motorway, then at a junction it cut out.
Its an 03 twin spark, serviced 3 weeks ago, tickover doesnt sound too low, and yes I am raising the revs enough on start off.
Any ideas on a cure would be most apreciated, cheers mark.

Mine used to do this, I had the bike dynoed and the dyno guy said that the lambda sensor was leaning the mixture off too much at tickover, as Id already took the cat off we disconected the probe, no more cuttting out. Might be worth a try, but if youve still got the cat fitted leaving it disconnected can apparently damage the cat.

If you havent a clue what Im talking about just say and Ill explain a bit more

You should do a zero=zero and most likely that will fix this issue.

Don't do it. Fix the underlying problem first, or you'll be chasing your arse for ever.

What is the tickover on your bike?

What is zero = zero ffs....???

zero / zero is a method of balancing the throttles..

Have you checked the battery is in good nick mark?

You would be well advised to listen to Mr Steptoe.

It's correctly adjusting the TPS (throttle position sensor). It is often to be found to have been set incorrectly at the factory, and very much capable of producing said problem.

No offense, but it can be the underlying issue. It is so easy to tell someone not to do something, without any reason WHY or offer any solution as an alternative. Same goes for boxadog.

a ha, my bike has a y piece fittedm(cat removed) so i guess lambta probe removal is prescribed!!!!!, It wont do it any harm will it?????
cheers for the replys guys.

no it wont do any harm, it only does anything at tickover basically, if your lucky like mine the plug is just up under the right hand side of the fairing

Zero zero is not just setting/adjusting the TPS.

You can adjust the TPS without touching the "factory set" butterfly screws, which doing a zero zero entails.

And if you've an underlying problem, you'll also be factoring that into adjustment.

I have said the reason why = you don't start adjusting things that have nothing to do with the problem. If you don't know what your doing you'll only be adding more problems to the equation.

Zero Zero, in my opinion is a lot of bollox that gets posted on the net, and people who aren't really 100% sure of what they're doing attempt to do ( usually for no other reason than they have a set of tools, and have read it on the internet), and end up in a far worse position.

I usually end up rectifying these problems, that didn't need doing in the first place - With just a spot on valve clearnce /end float and throttle balance.

Ill try and unplug the lambada and see what happens, All this talk of zzero zero makes me duck(over my head),If it doesnt work , off to the money pit (williams bmw) .
Thanks for all the advice guys. cheers mark.

If everything else checks out look at the coils. They seem to fail and the idle gets rough, there is a hesitation during roll ons and subject to stalling at idle. Coil replacement takes about 45 sec.

I agree, this is the most likely problem - I would go for new ones as the s/h hand ones I got seem to be going the same way now...
