Misfire when cold
 

As above when the Zed is started from cold it misfires horribly for 30 seconds to a minute and then it's fine again. Any ideas on what it could be? I doubt it's something like injectors or a fuelling issue as I don't think it would stop if that that was the case. I could be wrong however.

Properbly a sticky throttle body, or throttle position sensor or IACV or possibly a failed coolant temp sensor.

As above, there's a whole range of things it could be. I'd probably be looking at the ignition system, myself. Coil packs?

Well it is due a service soon so I'll replace the Coil packs and HT leads when I service it.
