* Engine Variations: Even within the FC420V model, there can be different versions with varying compression ratios.
* Wear and Tear: Compression ratings can change over time due to wear and tear on the engine.
* Service Manual is Key: The most accurate information for your specific engine will be in the Kawasaki FC420V service manual. It will list the proper compression range for your model.
Here's how to find the information you need:
1. Locate your engine's serial number: You'll find this on a tag attached to the engine.
2. Contact Kawasaki: Use the serial number to contact Kawasaki directly (through their website or by phone) to request the correct service manual.
3. Consult a local engine repair shop: They may have access to service manuals or can help determine the correct compression rating for your engine.
Remember: The compression rating is crucial for determining engine health. If your engine is not within the recommended range, you may need to investigate the cause and make necessary repairs.
