Runs fine cold start then really rough when warm - O2 sensor bad?

I would put a new battery in. This bike does wacky things when you have a weak battery in it. And having the same battery since 2011 is impressive.

Many problems have been solved with a new battery on this bike.

Yes, I think this is the best option. If all else fails, at least there will be a new battery in the bike!! Thanks

Hey Ben, I have a near new lithium spare battery if you're keen to pop out this way (Youghal). Happy to lend it until you get sorted. Last weekend I was at Halfords /Mahon Point and they had a couple Yuasa batteries that fit (XTZ12s) on the shelf.
