A motocross gear shifter can take a fair amount of abuse. The odd crash will put a lot of force on the gear shifter and it also endures a decent amount of punishment from being kicked down with considerable force when coming around fast corners. If the shifter has a loose, or wobbly feel – there could be a number of problems that warrant a replacement.
If the gear lever is off by just a year, it may not be compatible with your bike, rendering it essentially useless. Always ensure that the gear lever is compatible with your bike before you begin the process of replacing the shifter. With that said, here is how to fit a motocross gear shifter in 4 steps:
Step 1: Set the height of your gear shifter. The standard setting would be to place the shifter’s tip as close the level of the foot peg as it is able to go.
Step 2: Push the lever onto the gear shaft. Once the angle of the shifter is in an adequate position, it can be pushed onto the spline. Pull the locking bolt away to allow easy access. If the lever is the correct size, the shifter should be snug.
Step 3: Apply the locking bolt and pull it tight. It will either be a pinch bolt, or a capping bolt which is fastened against the very end of the gear selector shaft. Be sure to consult your bike owner’s manual for the suitable torque settings. The locking bolt is often small so be careful not to over tighten it, or the bolt may end up being stripped away.
Step 4: Check the gear lever action. Your lever shouldn't touch the bike frame, or the engine case. Gear selection up and down should be seamless and achievable. Make sure that you have the correct lever on for your bike.
With that, your shifter will be successfully replaced, and your bike is ready for a ride! Don’t be afraid to take it for a spin now that your hard work is complete.
