Stalling at idle

Is anyone else suffering from this? I think it is the cold, but here are the symptoms of my Fazer 6 1999.

Starts fine and runs good for 5 minutes, then engine gets stuttery and stalls if under 3K revs. Above about 5 or 6K revs, engine runs fine, but anything less and it sounds like not all cylinders are working. It pulls weekly, but the rev / speed ratio is the same as it is when running properly.

Anyway, after about 20 minutes riding and fiddling with choke and idle control, the problem just disappears.

I am putting it down to cold, but can anyone explain why the cold is doing this to my bike - or maybe people will suggest it is not just the cold.

Whatever - any thoughts on this are most welcome.

All the best,

Luke

It sounds as if it may be flooding a bit, if it stutters.

any thoughts? ...

1) onset of carb icing? esp in this weather ...
2) sticking choke mechanism - too much fuel for the low revs to deal with
3) shit coming through your fuel lines and trying to clog the idle jets ...

When was last time idle/pilot jet adjusted?
Suspect if set during a service when engine hot it may be a little too lean for when cold, especially with the cold snap we're in.

Will not be carb icing if, as you say, bike is at idle. Carb icing would be when you're going along and bike stutters like it's running out of fuel. Actually stopping and idling the bike will cure carb icing (until you start going again and it reoccurs obviously).

If bike stuttering like this it could be coils? Not enough voltage to work correctly then when warm and high revs enough to be sorted?
Would expect other symptoms with this though.

Just some thoughts, maybe not even in the right ballpark.
Please post with solution when sorted. Ta.
