Good To Know

Q: How many injectors does my engine use? A: The 1503 engine runs multiple injectors, so check how many cylinders need service and order the quantity that matches your application. This listing covers one injector.

Q: Can I replace just one injector? A: Yes, replacing a single failed injector is common, though some riders service the full set at once for even fuel delivery. Confirm your diagnostic results before ordering.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
