The latest Predator Engine is now 224cc with a 70mm bore and 58mm stroke crankshaft produced by Ducar for Harbor Freight Tools. This new engine increases output up to 10% more than previous models. This engine features the more popular non-Hemi head but uses many of the same parts as the Ducar 212 and Tillotson 212E.
The Predator 224 Cylinder Head features a 5.5mm valve in a Non-Hemi Head, similar to the GX200 Honda and 196 Clones. It also has plastic cam gear. If you want to increase power, especially with rpm, we highly recommend changing the camshaft.
