1. Locate the Oil Level Sight Glass
* On a CR250, the oil level sight glass is usually located on the right side of the engine case, near the bottom. It's a small, clear window.
2. Check the Oil Level
* Engine Cold: When the engine is cold, the oil level should be at the top of the sight glass, completely filling the window.
* Engine Warm: If the engine is warm, the oil will expand slightly, so the oil level will be higher in the sight glass. It's okay if the oil level is just below the top of the sight glass when the engine is warm.
3. Understanding the Sight Glass
* The sight glass often has markings or lines that indicate the minimum and maximum oil levels.
* If you see air bubbles or no oil in the sight glass, it's time to add oil.
Adding Oil
* Find the Oil Fill Hole: This is typically located on the left side of the engine case, near the bottom.
* Use the Correct Oil: Always use a high-quality, two-stroke engine oil specifically designed for your bike.
* Add Oil Slowly: Add oil slowly and check the sight glass frequently to prevent overfilling. Overfilling can cause serious engine damage.
Important Notes:
* Check Oil Regularly: It's essential to check your engine oil level regularly, especially before and after every ride.
* Oil Consumption: Two-stroke engines use oil to lubricate the engine and are known for consuming oil. Be prepared to add oil between rides, especially if you ride hard.
* Consult Your Owner's Manual: The best source of information about checking and maintaining your CR250 is your owner's manual. It will provide specific instructions for your model.
