Rebuild Kit for Accelerator Pump TOURMAX - Ref. ACK-901

The accelerator pump is a key component of the carburetor, responsible for momentarily enriching the mixture during acceleration. The TOURMAX ACK-901 rebuild kit allows you to replace the worn parts of this pump to restore a clean and consistent operation of the intake system.

This kit contains the essential parts to renew the accelerator pump without replacing the entire carburetor:

• Diaphragm (std size)
• Rod
• Spring
• O-ring(s)

Designed for the quad and motocross universe, this kit is aimed at both DIY enthusiasts and mechanics looking to perform targeted maintenance. Examples of models often affected: YAMAHA YFZ 450 2WD (2013), HONDA CRF 250 X (ME11) (2006), YAMAHA YFZ 450 SPECIAL EDITION 2WD (2009). Check compatibility with your carburetor before installation.

Replacing the diaphragm, rod, spring, and O-rings helps to correct leaks and slow drips responsible for hesitant acceleration. For optimal results, check the overall condition of the carburetor and follow the manufacturer's recommendations during reassembly.
