KEIHIN Throttle Slide PWK 28 - 6.0

KEIHIN offers this carburettor slide. The slide is a kind of sliding gate across the carburettor’s air passage: with the throttle closed it blocks almost all of it; with the throttle open it lifts and lets the air through.

Why change the slide?

The benefits:

• Replace a worn slide that has play and lets extra air through.
• Fine-tune pick-up just off idle: a different cutaway cures a flat spot or an over-rich mixture at the start of the throttle opening.
• Get back a throttle that moves freely and snaps shut properly.

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 slide that is scored, worn or loose in the body, or a split diaphragm on a CV carburettor: the idle becomes unstable, the engine draws in extra air and the throttle sticks.
