Let's locate the accelerator cable in your bike. Look at the right side handle of your bike. (direction from driver position)
After loosing the nut, lubricate the inside metallic cable with oil or spray. (Doers recommend to use throttle cable lubricant specified by vehicle manufacturer)
After sufficient lubrication, you can tighten the nut. With the help of plier tightly hold the metallic tube and tighten the nut slowly by rotating in clockwise direction till you get the enough tightness.
Now it's time to check the response. Letís check accelerator actuator response by slowly rotating accelerator actuator. If required, start the engine or take a test drive to understand the difference better.
If there is no improvement in the response or for vehicle service, contact your nearest certified Doers mechanic for door step service.
