It’s a simple way to refresh fuel delivery on older or modified 50–125cc engines — especially popular for Honda, Yamaha, Kawasaki, Suzuki and many GY6-powered machines. The chrome semi-flat (D) slide and included power jet let tuners refine mid- and top-end throttle behavior while remaining compact and straightforward to install.\u003c\/p\u003e\n\n\u003ch3\u003eWill this carburetor physically fit my engine?\u003c\/h3\u003e\n\u003cp\u003eMost fits depend on two key diameters: the intake manifold side and the air filter side. This MothAr PWK 24mm is built for engines whose intake manifold outer diameter is roughly 35mm and whose air-filter attachment measures about 50mm externally.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eIntake manifold outer diameter: 35mm\u003c\/li\u003e\n  \u003cli\u003eAir filter side outer diameter: 50mm\u003c\/li\u003e\n  \u003cli\u003eRecommended engine range: 50cc to 125cc (single and small multi-cylinder setups)\u003c\/li\u003e\n  \u003cli\u003eCommon-compatible models: many Honda, Yamaha, Kawasaki, Suzuki, SSR, TTR, TaoTao and GY6-based machines\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eHow does the PWK 24mm change performance and throttle feel?\u003c\/h3\u003e\n\u003cp\u003eThe 24mm bore size and D-shaped (semi-flat) throttle slide produce a quick, linear throttle response suited to lightweight engines and race-tuned small displacement bikes. The included power jet gives you an additional tuning circuit to control richer mixtures at higher rpm, helping peak power once the carb is correctly jetted for your setup.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003e24mm venturi for improved airflow over restrictive stock carbs\u003c\/li\u003e\n  \u003cli\u003eD-type throttle slide yields sharper throttle transitions\u003c\/li\u003e\n  \u003cli\u003ePower jet allows fine tuning of high-rpm fuel delivery\u003c\/li\u003e\n  \u003cli\u003eSimple needle and jet changes support progressive tuning\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat installation and tuning steps should I plan for?\u003c\/h3\u003e\n\u003cp\u003eInstallation is straightforward for mechanically inclined riders, but you’ll need basic tools, hose clamps and possibly an adapter or manifold gasket to obtain a perfect seal. After mounting, expect to adjust the pilot jet, main jet and needle height to match altitude, exhaust and air filter changes.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eVerify manifold and filter diameters before fitting\u003c\/li\u003e\n  \u003cli\u003eUse a new gasket and secure clamps for airtight connections\u003c\/li\u003e\n  \u003cli\u003eStart with stock jetting and make incremental jet\/needle adjustments\u003c\/li\u003e\n  \u003cli\u003eCheck for air leaks, smooth idle, and correct high-rpm behavior after tuning\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat materials and features help durability and serviceability?\u003c\/h3\u003e\n\u003cp\u003eThe MothAr PWK 24mm uses a chrome semi-flat slide and a power jet design that’s familiar to tuners, making it easy to find replacement jets and spares.

It’s suited to projects where improved throttle response and easier tuning are desired, and for anyone replacing an aged stock carb or building a performance-focused small-displacement engine. Note: confirm manifold and filter diameters before purchase and perform proper jetting to match your exhaust, elevation and riding style.\u003c\/p\u003e\n\u003csection class=\"product-faq-snippet\"\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Which engines will the MothAr PWK 24mm fit?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: It fits many 50cc–125cc engines with ~35mm intake manifold and ~50mm air filter mounts; check your diameters before buying.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Does the carb require additional parts to install?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: You may need clamps, a gasket or an adapter flange; jet changes are recommended for proper tuning.\u003c\/p\u003e\n\u003c\/div\u003e\u003c\/section\u003e","brand":"MothAr","offers":[{"title":"Default Title","offer_id":67590452215993,"sku":"B074HBG6BW","price":75.47,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0822\/3765\/3177\/files\/mothar-pwk-24mm-front-view.jpg?v=1790534684","url":"https:\/\/redleafauto.ca\/products\/mothar-pwk-24mm-carburetor-for-50-125cc-engines-d-slide-adjustable-power-jet","provider":"Redleaf Auto","version":"1.0","type":"link"}
