The lock-out on my Suntour fork is not working. How do I fix it?

Lock-Out Top Cap Fix for Suntour Suspension Forks

Tools Required:

Small Flathead Screwdriver

5mm Hex Tool

4mm Hex Tool

Needle Nose Pliers

Your new Voltbike may have a Suntour front suspension fork that has a dual
position lock-out dial on the RH side that allows the rider to open and lock the
suspension travel of the front fork.

If the lock-out dial stops functioning, follow the steps below to fix this feature:

Carefully remove the plastic top with a small flat head screwdriver

Remove the small dial control shaft using your needle nose pliers.

Use a 5mm hex tool to ensure the internal leg shaft is tight. (Do not over tighten)                     

Check the lock and open positions are functioning. Turn the 4mm hex tool
clockwise until the shock is in the locked position. Then turn the 180 degrees counter clockwise to check and set the open position. 

Re-install the small dial control shaft 

Orientate the top dial cap to the forward / open position and carefully press
and snap it straight down to engage securely with the lower part of the plastic
top cap.

The Open / Lock-out dial should now function properly.

The LH dial is a mechanical spring preload that will stiffen the fork when turned
clockwise, and will soften the suspension when turned counter clockwise. Fork
legs should be cleaned periodically and a few drops of light weight bike oil
applied to the legs near the dust seals.
