if the idle speed is close to 1150 you can adjust it by the little shifting of big screws on throttles but is very improtand these big sscrews must be 2 full truns from closed. You can open until 2 +1/2 and maybe the idle speed will be ok.
Also you can adjust the idle speed by little shifting of TPS. The TPS can adjust from 0,35-0,40 Volts.
These are the easy way.
Finaly you can adjust it by the little screws behing the throttle (by pass stop screws).

Buit there is a tip by this ways.
1. SET THE TPS to 0,36 Volts.
2. Sycronizations by the ritgh throttle cable on 3500 rpms.
3. Sychronization by the big screws on throttle to 1.600 rpms (must be arround 2- 2+1/2 full turns from closed.
and finally.
4 Adjust and sychronization the idle speed by the little bypass stop screws behing the throttles
but.. you must connect the tools Voltometer to TPS and the sychronization tool and when shifting the left by pass screws you must adjsut the tps again to 0,37 Volt then CLOSE KEY AND RESTART ENGINE, readjust the little screws and TPS, CLOSE RESTART AGAIN. Thats the reason, or secret that many mechanics say NO DO NOT ADJUST THESE LITTLE BY PASS SCREWS !!
until ..
1. Iddle speed is both sycronization and to 1.150 rpms, 2. TPS,. to 0,366 Volt.
ATER ALL SETTINGS THE BIKE :
Has perfect sychronization from iddle speed, low rpms (1.400-1.900) and middle rpms (2.000-...).
Has perfect idle speed.
has the more air at low rpms (1.1100-1.900 rpms) for BETTER START RIDING THE BIKE.
and finally BETTER CONSUMPTION.
