Motoforce Racing PWK 28 - 34 mm carburetor, chrome version

To improve the performance of your motorcycle, scooter, or moped, you should install a larger carburetor. This 2-stroke PWK carburetor offers excellent performance at a truly affordable price.

What is a PWK carburetor?

PWK carburetors are larger-diameter tuning carburetors designed primarily for racing . They feature a fuel inlet, a chrome-plated flat slider, a Powerjet, a large float chamber, and a lever-operated choke. There are two groups:

• 28mm to 30mm models: intake connection width 35mm and air filter connection width 50mm.
• 30mm to 34mm models: intake connection width 40mm and air filter connection width 55mm.

In terms of performance, the carburetor offers better throttle response and better fueling at high rpm. This improves engine response and increases top speed.

What size carburetor do you need?

It's very important to size the new PWK carburetor correctly: neither too large nor too small! If it's too small, the engine could overheat, while if it's too large, fuel consumption will be unnecessarily high and performance will be inadequate.

Here's a guideline:

• PWK carburetor 28 mm (HD 135, ND 55, PJ 32) ==> 70-80 cc Racing / High-End Racing
• PWK carburetor 30 mm (HD 140, ND 55, PJ 32) ==> 80-90 cc Racing / High-End Racing
• PWK carburetor 32 mm (HD 160, ND 55, PJ 32) ==> 80 - 90 ccm High-End Racing
• PWK carburettor 34 mm (HD 160, ND 55, PJ 32) ==> 90 - 100 ccm High-End Racing

Please note: When installing this type of carburetor, the original intake system can no longer be used; a larger intake manifold or a larger intake rubber with a diameter of 35 mm or 40 mm is required. Additionally, the original throttle cable, original air filter, and original fuel tap must be replaced with a non-vacuum model.
