This is driving me mad,,, The bike runs but will NOT TICKOVER or run below 3k revs on rear cylinder ,front cylinder and carb are perfect,

I have rebuilt the carb 4 times now with new parts it has been thoroughly cleaned , in ultrasonic bath twice , blasted with air ,, each time I have fitted it the fault is still the same ,,it has new float , new gaskets, needle, airscrews, even the pilot air cutoff valve is new ,,,baffling ???
The right hand front cylinder carb is fine

I have put other spark plugs , HT leads , coils and igniter units they are from one of my other bikes but the fault persists so its not Electrical ,, There are NO airleaks I have now spent some 80 hours on thsi one problem and im run out of ideas ???? totally baffled
