●Clear throttle
●Change throttle
●Uninstall and install idle speed control valve
Solutions
Solutions:
Using OBDSTAR MS80 to operate on following tests:
【(54)ISC(idle speed control)valve/FID(fast idle solenoid)】
【(67)ISC correction value erasure】
【(87)Air-fuel control learning data erasure】
Detail Steps:
①Connect MS80 to Motorcycle, enter into【Moto Diag】;

②Click【All】, input letters such“YAM”in search bar, click【YAMAHA】;

③Click the newest YAMAHA edition;

④Click【Select from system】;

⑤Click【Auto Scan】;

⑥Turn off the ignition, click【Enter】;

⑦Turn on the ignition, click【Enter】;

⑫Click【Actuator Check】 three times within 5 seconds;

⑬Operation successful, it shows 0;

⑭Click【(67)ISC correction value erasure】;

⑮Click【Actuator Check】 three times within 5 seconds, then ISC correction value will be erased;
Notes:
00:the ISC correction value has been erased;
01:no need to erase the ISC correction value;
02:erase the ISC correction value.

⑯After ISC correction value erasure, it shows 0;

⑰Click【(87)Air-fuel control learning data erasure】;

⑱Click【Actuator Check】 three times within 5 seconds to erase the air-fuel control learning data.

⑲After air-fuel control learning data erasure, it shows 0.

Summary
If Motorcycle has idle speed instability or a little bit high after uninstalling and installing, clearing, changing throttle, operate on erasure of ISC correction value and air-fuel control learning to solve the problems.
