ASP 400 FS 5 Cyl Radial

64.00cc, 5 cylinder, ringed, includes manifolds but no silencer included as standard.

The mounting ring is 122mm diameter and has five fixing holes that are around 72mm apart, the engine is 200mm long from mounting holes to prop nut and 110mm radius from rocker cover to centre of shaft, so double that for required diameter. As the cylinders are slightly offset measuring directly across the engine is difficult.
