Quick Overview

Keihin PWK 28 Carburetor, as used on most of the works trials bikes. The half flat D slide Carburettor gives a smoother more responsive bottom end and improved mid range, while the larger bore allows the engine to breath more freely giving a large boost to the top end of the rev range.


Equivalent to Sherco Part number 1123.


As the carb comes supplied from Keihin, it requires a few modifications to allow it to be used on a trials bike, these are listed in the options below, the default selections give a good starting point for GasGas and Sherco trials bikes.

Fitting recommendations for the Sherco trials bikes:

The PWK will with a bit of persuasion fit into the original rubber manifolds but it does stretch them which may lead to premature failure of the rubber, the airbox manifold is the worst affected so it is highly recommended to purchase this Keihin airbox manifold, the inlet manifold between the carb and the reed valve can be just simply chamfered to allow easier fitting, then when the carb is inserted it stretches the rubber so the internal diameter matches the diameter of the carb giving a smoother flow path. The Keihin manifold is just the standard one with a bit roughly cut out to allow easier fitting of the carb, this leaves a step from 28mm to 26mm in the flow path.
