Adjusting the valves on a scooter is not an easy task, nor should it be completed without the proper tools or experience. For those who feel comfortable with this job, you’ll probably know that each manufacturer has specific rules and guidelines on valve lash (clearance) and how they should be set. Noted below is a basic instructional list of steps that you should complete when adjusting the valves of a scooter purchased through Variety Powersports. If you have any hesitation on completing this job 100% accurately, please STOP and have an experienced mechanic complete valve adjustment as needed.
First, a few indicators on when valves should be adjusted. When a valve’s clearance from the rocker arm and valve stem is too large, the valve doesn’t open up fully (and you’ll probably hear a clicking or knocking sound). Conversely, if the valve lash is too tight, the valve won’t close or open fully or correctly, leading to poor engine performance and in some cases, compression or exhaust issues that can cause major mechanical damage. For those who feel comfortable moving forward, noted below are a few important steps to follow about adjusting valves on a scooter motor.
Adjusting valves should only be completed after contacting the sales and technical team at Variety Powersports to ensure any warranties or other issues are handled appropriately. Our technical team can help you with the proper valve adjustment settings and also help you find a local mechanic that is certified to work on your specific brand of scooter if needed.
