Bike keeps jerking when throttle even aft rpm 8-9

[atrophy]

i guess its the air and fuel ratio..

 

ask ur mech to do some tuning..

[chuan.z]

ever happened to me once on my old ride Sparks135...issue rectified by replacing spark plug. Mechanic used wrong spec spark plug for my bike...

balancer perhaps?

[racingter]

either spark plug or carburator .

 

Once my ST11 pump petrol in JB...

 

come back also encounter this problem..then my friend told me it's the petrol...

 

they mixed with kerosine...

 

After that i pump in a full tank of local petrol then no more problem...
