Not exactlyLike most bikes, it has to idle high to warm up before cracking the throttle to full!
Certainly a more in depth explanation. Note that there are no jets though.Not exactly
All properly-jetted petrol engines need extra fuel when the metal is cold as the fuel tends to simply run along the cold metal surfaces as droplets which won't burn. Adding fuel or decreasing air richens up the air/fuel ratio to provide a volatile mixture that will burn regardless of the unvapourised fuel. Higher idle is a useful side-effect of this as it allows the engine to warm up faster, at which point all of the fuel is properly vapourising creating and a mixture that is far too rich for efficient combustion.
