Throttle cables
I have done it! put the l/h cabledown as far as it will go and make sure theres no slack adjust so it moves the pully at the slightest movement of the tyhrottle with a slight bit of slack obviously. Then syncronise with the right cable adjuster.the tick over being set by the air screws.
I know certain people will say cobblers but it works for me so na.
