Hi,

So far I was riding without any adjustment from the factory but idle is definitely too fast like 2400 rpm.

I turned air screw out 1.25 as in manual and was trying to adjust with the idle screw to stated in the book 900-1100RPM 

but if I go that low bike starts to die. What idle do you run?

I think its the air mixture screw which is normally between 1 - 1.5 turns

my idle screw was set afterward to a comfortable level just above stalling, certainly isn't screwed that far in 

thanks

Place bike in 1st gear, set idle so that the bike will putter around with no throttle input without stalling.

 

Often the idle channel is clogged, use an ultrasonic cleaner (€50 on Amazon) to free the carburetor.
