Lambretta PHBH 28mm carburettor kit supplied with YSN aftermarket carburettor.

Manufactured to PHBH specification and compatible with Dellorto jets and components. This is an aftermarket product and not a genuine Dellorto carburettor.

The 28mm PHBH is typically suited to 200cc and larger capacity Lambretta engines, as well as tuned or performance builds requiring increased airflow and higher fuel demand.

Each kit is jetted according to engine specification. Setup takes into account cylinder size, porting level, exhaust type and intended riding style.

Typical configuration may include:
• Atomiser selection appropriate to engine tune  
• Main jet range suitable for high-load operation  
• Needle and slide combination matched to mid-range fuelling  
• Correct idle jet for stable low-speed response  

This provides a strong baseline for further fine tuning where required.

Readspeed are experienced Lambretta tuning specialists with dyno facilities available for precise carb setup and optimisation.

Kit includes:
• YSN PHBH 28mm carburettor  
• Manifold  
• Gaskets and rubber fittings  
• Extended throttle cable  
• Jet and atomiser pack matched to application  

Important:
Full engine specification must be supplied when ordering to ensure appropriate jetting.
