Briggs & Stratton no longer produces this engine in its assembled format. The Raptor Racing Engine is now in the form of a kit engine. The kit will consist of most of
the components needed to assemble a Raptor Racing engine less the parts that are usually replaced with after market components such as cam, valve springs, lifters, flywheel, etc.
Below is a list of the components that will be included in the kit engine and their separate part numbers. Also be mindful that the engine comes with a +.010" oversize piston, so
the cylinder will have to be honed or bored to fit the piston.
