{"product_id":"billetron-pro-125cc-300cc-carburetor","title":"Billetron Pro 125cc-300cc Carburetor","description":"The Lectron Billetron Pro is a high-performance, track-adjustable carburetor engineered to replace stock components in 125cc-300cc two-stroke motorcycles. Developed in collaboration with professional engine builders, this unit utilizes an engineered bore design to maximize volumetric efficiency and airflow dynamics. Its three-circuit fuel delivery system—comprised of a metering rod, torque jet, and power jet—allows for isolated, real-time adjustments across the powerband, enabling riders to precisely tune air-fuel ratios without complex jet changes.\n\nTechnical specifications include a 46mm spigot OD for the engine intake, a 62mm bell OD for the air intake, and an overall length of 78mm. The carburetor is equipped with a throttle position sensor (TPS) and a constant vacuum jetting system, which ensures consistent fuel delivery and immediate response.\n\nInstallation requires careful verification of physical clearance; please measure your bike's intake dimensions against the provided 46mm spigot and 62mm bell diameters to ensure proper fitment.","brand":"Lectron Fuel Systems","offers":[{"title":"Default Title","offer_id":52686604337464,"sku":"1138-LB","price":805.58,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/658281971.jpg?v=1784875255","url":"https:\/\/store.motormia.co\/products\/billetron-pro-125cc-300cc-carburetor","provider":"MOTORMIA","version":"1.0","type":"link"}
