Dear otai FZ,

I am getting a very strange behavior out of the bike recently.

3 scenarios and I purposely repeated it many times and it happens without fail

1st scenario
a. Going downhill. Engine braking at 4th gear. No throttle/gas.
b. 20 seconds downhill, sharp turn left.
c. Engage clutch before the turn and down shift to gear 2.
d. Engine cut off when downshifting during the cornering
e. Engine can be restarted

2nd scenario
a. At the traffic lights, downshift to 1st Gear.
b. Clutch engage.
c. Engine dies off by it own or when I shift to 1 gear in preparation for the green light.

3rd scenario
a. Parked and go makan
b. Start engine in Neutral
c. Engine dies after a while.


I have changed
1. Fuel Filteher
2. Clean Throttlebody
3. New spark plug
4. New rectifier

Voltage reading is ~13.5

Any ideas on what is happening or what else to check?

Engine is smooth. Bike is OK. This is driving me nuts!

Thanks in advance.

engine idle low can cause 1,2,3
short clutch can cause 1,2

Thanks. Any idea how for adjustments?

Clutch adjustment probably easier to let the bike shops help you...

Idle screw adjustment:
not sure if malaysian FZ throttle body is the same but from youtube...
