Bidalot Kawasaki KX 85-derived V-Force3 lamellar valve power system. The kit includes an adjustable manifold with its support. Carburetors with external ink from 35mm type PWK or VHST can be used. The V-Force lamellar package is modified by BIDALOT to fit easily in the crankcase. This is slightly machined on the sides to finish on a precise and constant width of 39.9mm. However, it still needs small work to the crankcases for perfect assembly.
