I have a 2005 VTR1000F (Superhawk in the USA, Firestorm here in Australia) with 32,000 km on the clock, which runs quite poorly when cold.

It won't idle with just the choke, it needs a bit of throttle too. Every 5 to 10 seconds it will misfire (I think this is what is happening) -- instead of a normal "boom" of a cylinder firing it just sounds like a very loud cough or puff. Once it's up to temperature it's fine -- no misfiring, idles at 1000 rpm no worries. I have noticed maybe one or two times I've heard the same "misfire" sound when it's up to temperature, but not anywhere near as often as when it's cold.

I was thinking it's either a damaged/misadjusted carb or spark plugs. I'm going to replace the plugs. I'm not really confident in dismantling the carbs (though I do have a service manual for it) as this is my only method of transport. Is there anything else I might be missing?
