The design uses a \u003cstrong\u003eflange-style carburetor mount\u003c\/strong\u003e, making it compatible with a variety of carburetors that share the required mounting pattern and dimensions.\u003c\/p\u003e\n\u003cp\u003eThe manifold was developed and tested around a \u003cstrong\u003eNibbi PE17FL\u003c\/strong\u003e, but is not limited specifically to the Nibbi carburetor.\u003c\/p\u003e\n\u003cp\u003eInternally, the carburetor outlet transitions into a \u003cstrong\u003e20mm runner\u003c\/strong\u003e that maintains its cross section through the majority of the intake before smoothly expanding to the factory reed cage opening. This keeps unnecessary intake volume to a minimum while still distributing the incoming charge across the reed cage.\u003c\/p\u003e\n\u003cp\u003eThis manifold started as a solution for my own BW80 after discovering it had been fitted with a PW80 engine. The first prototype successfully ran, tuned and rode, and the design has since gone through multiple revisions based on what I learned from the original.\u003c\/p\u003e\n\u003cp\u003eThe current version is printed from \u003cstrong\u003eFiberon PA612-CF15 carbon-fiber reinforced nylon\u003c\/strong\u003e and annealed after printing for improved mechanical and thermal performance.\u003c\/p\u003e\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eDesigned for Yamaha PW80 engines\u003c\/li\u003e\n\u003cli\u003eFits PW80-powered Yamaha BW80 builds\u003c\/li\u003e\n\u003cli\u003eUniversal flange-style carburetor mounting\u003c\/li\u003e\n\u003cli\u003eDeveloped and tested using the Nibbi PE17FL\u003c\/li\u003e\n\u003cli\u003eShort, direct intake path\u003c\/li\u003e\n\u003cli\u003e20mm internal runner\u003c\/li\u003e\n\u003cli\u003eSmooth transition to the factory reed cage\u003c\/li\u003e\n\u003cli\u003eReduced pre-reed chamber volume\u003c\/li\u003e\n\u003cli\u003ePA612-CF15 carbon-fiber reinforced nylon\u003c\/li\u003e\n\u003cli\u003eAnnealed after printing\u003c\/li\u003e\n\u003cli\u003eThick mounting flanges\u003c\/li\u003e\n\u003cli\u003eMetal crush sleeves at mounting points\u003c\/li\u003e\n\u003cli\u003eDesigned and tested by Cerealnaut\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eCarburetor Fitment\u003c\/h3\u003e\n\u003cp\u003eThis manifold was designed around the \u003cstrong\u003eNibbi PE17FL flange dimensions\u003c\/strong\u003e, but the flange-style mounting system allows other carburetors with compatible bolt spacing, flange dimensions and outlet size to be used.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eAlways verify your carburetor dimensions before ordering.\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCarburetor mounting bolt spacing:\u003c\/strong\u003e 48mm center-to-center\u003cbr\u003e\u003cstrong\u003eCarburetor-side opening:\u003c\/strong\u003e 24mm\u003cbr\u003e\u003cstrong\u003eInternal runner:\u003c\/strong\u003e 20mm\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e1 × Cerealnaut PW80\/BW80 performance intake manifold\u003c\/li\u003e\n\u003cli\u003eMetal mounting\/crush sleeves installed\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eCarburetor, reeds, gaskets, mounting hardware and other engine components are not included unless specifically stated.\u003c\/strong\u003e\u003c\/p\u003e\n\u003ch3\u003eImportant Fitment Note\u003c\/h3\u003e\n\u003cp\u003eThis manifold was developed using an original Yamaha PW80 engine installed in a nearly 40-year-old Yamaha BW80.
