Posting for my brother-in-law. These are listed cheaper than you can buy them new, they are complete kits that have never been mounted to a kart. The engines run strong, much more mid-range than the IAME Leopard or X30. Please contact Taylor at 620-757-1981 or email tdeverhart.27e@gmail.com and I will give you his contact information.
