1. Oil Level - Check the oil level in your oil reservoir. If the level is low, it could indicate that the oil pump is not working properly.
2.Oil Indicator Light**- Most Yamaha Blasters have an oil indicator light on the dashboard. If this light is illuminated, it could indicate that the oil pump is not working properly.
3. Oil Pressure Gauge (if equipped)- If your Yamaha Blaster is equipped with an oil pressure gauge, you can use this to monitor the oil pressure. If the oil pressure is low, it could indicate that the oil pump is not working properly.
4. Visual Inspection**- You can also visually inspect the oil pump to see if there are any obvious problems. Look for leaks, cracks, or other damage to the oil pump.
If you suspect that the oil pump on your Yamaha Blaster is not working properly, it is important to have it checked out by a qualified mechanic to prevent any damage to your engine.
