This is PART 1 of the full step-by-step external shift linkage inspection for your 1997-2001 Honda CR250 Dirt Bike.
When was the last time you performed 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, and that could damage other internal parts. A common Honda CR250 external shift linkage problem is having problems getting your bike into gear. There is no definite cause for this problem, so you will have to inspect every part of the linkage.
The Tools You Will Need Are
- 8mm socket
- 10mm box wrench
- 2 Pry bars
- You will need to remove the right crankcase cover and clutch assembly to access the shift linkage. You can see how to do this in the Clutch Inspection Walkthrough.
- I highly recommend using OE parts. Aftermarket parts may be cheaper, but they may not be the same quality as the original Honda parts.
- I recommend opening the Service & Torque Specs table in a new tab for easy reference.
- If you need parts and tools, make sure to buy them here!
- Put a box or tray under your bike to catch falling parts.
- The external shift linkage has many tiny components, so make sure to keep everything in a Ziploc bag!
- Pictures with captions are after the steps below.
- Honda OEM part numbers listed at the bottom of the page.
