dont use a colourtune


plug chop it`s a better result as the enginges  working under load and in natural  enviroments  etc




colour tunes only work as the bike is idle  ie not moving so only in stale surrounding n still run weak !!!!!! not good


ive set many engines even on rollling roads  and still  refered back to plug chop !

I've used colortunes for 34+ years and it works

you mention that the bike is idle and a "stale" surrounding; you set many on a rolling road - what , set the pilot screw mixture on a rolling road? WTF?  I must be a dumbass as I dont know why one would  set an idling circuit on a rolling road  :eek etc.etc. Come on mate, you kno this but...ahem, the pilot screw only adjusts the mixture for idle principally, so idle and not moving is what is required for pilot screw adjustment - albeit the bike needs to be warmed up. The colortune provides a visual cue to the mixture which whilst not perfect is far better than the audio "listen to the RPM" and more accurate. Its not perfect, but a better solution. I have to say I find your comments most illogical but hey, you are entitled to your view and if your approach has worked then disregard my shite and carry on turning the pilot screw while the bike is motoring along on  a rolling  road
