KEIHIN PWK39 Standard Carburetor

KEIHIN offers this carburettor. The carburettor sits between the air filter and the engine and prepares the air-fuel mixture the engine will burn.

Why change the carburettor?

The benefits:

• Replace a carburettor that is worn, cracked or impossible to set up, rather than repairing it again and again.
• As part of an engine build, a bigger or more modern carburettor improves filling and throttle response.
• A new, complete unit: body, slide, jets and needle already fitted.

Why choose KEIHIN?

Keihin, founded in Japan in 1956 and long nearly half-owned by Honda, supplies original equipment to Honda as well as Suzuki, Kawasaki and KTM; its FCR carburettor, whose flat slide runs on roller bearings, was developed in Superbike racing.

When should you replace this part?

A cracked body, a slide with play in its bore, damaged threads or carburation that cannot be stabilised despite a full clean: the carburettor needs replacing.

Specifications and fitting tips

• Chromed semi-flat (D) throttle valve for excellent response and more flow at high RPM.
• Throttle bores sized to give maximum power.
• Manufacturer part number: 1000-72R-AB0

Cross-Mania tip: Check the diameter of the inlet manifold and the airbox connection, the type of throttle cable and the routing of the vent hoses, then fine-tune the setting (jets, needle, mixture screw) with the engine warm, starting from the setting supplied.
