The intake manifold is suitable for mounting connecting rubbers with 60mm hole stitch.These are available in two different diameters, suitable for carburettors with Ø24-25mm and Ø28-30mm cross section. The inlet cross section of the intake manifold is the same as the bgm Pro RT cylinder kit, therefore no adjustment is necessary.
