honda cbf 125 cold idle problem

[englishboy]

Hi need help!! My beloved Honda CBF 125 09 plate has started cutting out when i start it and leave it tick over, also if i ride it straight away and don't keep the revs up will cut out. Some time its a struggle to restart, but when the bike is warm there's no problem and it runs like a dream . I know its been cold lately but even when we had nice weather the other week I still had problems starting it. The bike has just done over 700 miles, any help would be great thanks.

I too have similar issues, just let it warm up for a minute before you go or keep the revs just above idle when your at lights and such after a minute on the road all will be well, hope that helps

what's the spark plug look like?/do the valves need checking?

At 700 miles?

I'd start by having a look at the oxygen sensor.
