My NC23 has started to idle on just 2 cylinders.... the outer? (sorry I don know the cylinder numbers) but when riding over 6k it's fine.

Does anyone know what this could be? I'm taking a guess at a faulty coil pack and have purchased one which should be here in a couple of days.

I was just wondering if anyone else had a similar issue and what was the cause of the fault.

Cheers
Andy

If it's 1 and 4 then I'd agree it's the coil pack or dodgy wiring to that coil pack.

Do you know if the cheapy ones from eBay are any good? wemoto have them too, but they're £60. Ebay is £30.
