Keihin PWK 28 Customised to your specifications - Right Idle

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.

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 Beta and Scorpa SY250 trials bikes.

Please see here for more information on the modifications required or if you fancy having a go yourself.
