Connector Features: Utilizes a motorcycle-specific radiused polygon female connector to ensure precise compatibility with specific vehicle wiring harnesses.
2. Harness Design: Features an extra-long 26.1-inch (663mm) harness design suitable for vehicles with unique engine compartment layouts. Proper routing planning is required during installation.
3. Installation Notes: Features an M12×1.25 thread specification with a recommended installation torque of 18-22 N·m. Verify connector orientation before installation to prevent forced mating.
4. Tolerance Statement: Product dimensions may exhibit 1-3mm manual measurement tolerances, which fall within normal industrial manufacturing ranges.
Fuel nozzle fault performance:
1.Fuel hole is clogging
2.Poor sealing. Poor sealing of the needle valve and the needle valve body, resulting in poor atomization or oil leakage of the injector
3.Has air in the oil circuit
4.Poor oil supply
5.Insufficient spring force of the piston spring or spring break
6.Piston wear, which affects oil supply
How to judge the injector is clogged or damaged?
1.Engine noise is getting bigger, especially in low gear and below 2500 rpm
2.The throttle response is not sensitive, the acceleration is not smooth, and the throttle will have obvious hysteresis.
3.The idling range is small, especially when starting, the jitter is obvious, and it is not easy to eliminate. The 1st and 2nd gears have a slight lack of cylinder feel.
4.Engine fault light is on
