Bike stalls when I click clutch

[Wahdib]

Whenever my bike is running and I click the clutch to rev the motor it stalls straight away, can someone help me with this please?

Need more info, are you saying that when you pop the clutch, the engine bogs?

 

[Wahdib]

Yes, that's exactly what happens

Pedal as you start up! Go easy on your clutch!
