Hi Crash! - not sure about the handle
but welcome.
Everyone is welcome at the Cornerspeed gathering, I just hope the recent weather holds on for us.
Not sure about the idle problem - in my experience they can idle a fair bit faster when warm, I've set mine so its about 1000 rpm after a quick warm so then = 11/1200 after a 'rapid' ride
Wouldnt of thought it was ignition so carbs would my most likely suspect.
Cheers - Frank
