Description


NO PWK 28 carburettor. Carburettor equipment: Side jet 50, main jet 135, needle JJH, slider 3,5.
The connection width is 34 mm. The air filter connection 49 mm.
Very powerful alternative to Dellorto and Mikuni carburettors. Extremely high quality.

The KEIHIN PWK carbs are the most copied carbs worldwide. And not without good reason. So the KEIHIN PWKs are the reference class in the range of 2-stroke carburettors.

The KEIHIN racing carburettors are not only first choice in all areas of motorsports!

KEIHIN's decades of experience have been incorporated into the development of the carburettors, so that this really powerful carburettor reacts very well to changes in setting. The fine tuning results in very good throttle response, producing good power over the whole rev range: The PWK carburettors react very sensitively to the adjustment of the mixture screw.
If the engine sticks to a too high speed after full throttle, the side jet is usually too fat. In order to achieve an acceptable idle speed with the too rich auxiliary jet, the idle speed is usually increased and the mixture screw is turned out too far (= leaner).

This compensation of the rich auxiliary jet via the settings on the carburetor leads to the engine getting stuck at a very high speed, although the gas has already been turned back to zero.

With a smaller auxiliary jet the idle speed can be adjusted to a normal level and the idle mixture can be adjusted (screwed in) via the mixture screw to a richer mixture. This is often adjusted inadvertently when dismantling the float chamber. To do this, always remove the float chamber with the carburettor upside down. Otherwise the float can get caught in the inclined overflow pipe.

Recommended float level PWK28: 19mm (Turn the carburettor upside down here too: Measured from sealing edge of float chamber to upper edge of float ).

Sehr guter Vergaser, kompakt sodass er mit MRP Membran in eine Sprint passt, jedoch Standgasschraube auf der falschen Seite sowie Leerlaufgemischschraube nicht zugänglich - Vergaser muss dafür ausgebaut werden
