When did you last perform a full external shift linkage inspection on your motocross or trail Honda CR250?
Your External Shift Linkage might be bad, and you don’t even know it, which could damage other internal parts. A common Honda CR250 external shift linkage problem is having problems getting your bike into gear. This problem has no definite cause, so you must inspect every part of the linkage.
The Tools You Will Need Are
- 8mm socket
- 10mm box wrench
- 2 Pry bars
Pre-Service Notes
- To access the shift linkage, you will need to remove the right crankcase cover and clutch assembly. The Clutch Inspection Walkthrough explains how to do this.
- I highly recommend using OE parts. Although aftermarket parts may be cheaper, they may not be of the same quality as the original Honda parts.
- I recommend opening the Service & Torque Specs table in a new tab for easy reference.
