Hi,

Check that the new plugs are all working and gapped correctly.
It is not un-common for new plugs to be faulty! Shocked

Could be fuel or electrical problems. You could start by checking the coils as per the specification in the haynes manual.

Has it suddenly developed or did it happen after the bike's been idle for a few weeks? If it's the latter, I'd go for a fuel-related cause first, e.g. blocked idle jets as suggested. Just putting fresh petrol in doesn't clear out the goo that forms in the jets when ordinary 95-octane evaporates off.

Thanks for letting us know, well done for sorting it out.

If I may ask a stupid question, the stuck needle any idea why or how this could have happened?

Brill - Glad you got it sorted.

So what makes a needle stick and more importantly how do you unstick it?
