Bultacos: Alpinas, Sherpa Ts, Sherpa S, Fronteras, Matador, Pursangs, Metralla 62
To date we have probably fitted more Bultacos with OKOs, both the K-101 series and the K-104 series, than any other brand of motorcycle.  In the sixties some Bultacos used spigot mount carburetors.  Through the mid-seventies, most used flange mount carburetors, and after that Bultaco went to all spigot mounts.  We have kits for many models, including the 250 and 350 Alpinas, the 250, 326 and 340 Sherpa Ts, 250 and 370 Fronteras and the 370 Pursangs.  For other models, we just need to know the manifold size and the model you need a carburetor for.  Photos below show kits for both flange mount and spigot mount models.  If you don't see what you are looking for, contact us at usaoko@comcast.net or call us at 410-635-6722.
