Throttle Operation
2000-2003 TRX350 Rancher ATVs
Check for any deterioration or damage to the throttle cable. Check the throttle lever for smooth operation. Check that the throttle opens and automatically closes in all steering positions.
If the throttle lever does not return properly, lubricate the throttle cable and overhaul and lubricate the throttle housing.
For cable lubrication: Disconnect the throttle cable at its upper end. Thoroughly lubricate the cable and its pivot point with a commercially available cable lubricant or a light weight oil.
Note
If the throttle lever still does not return properly, replace the throttle cable.
With the engine idling, turn the handlebar all the way to the right and left to ensure that the idle speed does not change. If idle speed increases, check the throttle lever free play and the throttle cable connection.
Measure the throttle lever free play at the tip of the throttle lever.
