Valve Shim Kit (7.48mm OD)
The CRF250R utilizes a shim-under-bucket design where intake valve recession common to this model eliminates necessary clearance, preventing the valve from sealing against the seat during cold starts. Restoring the OEM-specified clearance using thinner shims allows the valves to close fully, restoring the compression required for ignition. This is the standard mechanical procedure for resolving cold-start issues on this specific engine architecture.
