A very detailed model of a Go Kart Single Cylinder Motor. Includes chain link drive, Carb with air cleaner, and expansion chamber exhaust. Many molded parts with 173 total pieces. Taken from the Shifter_Kart model, yet can be used on watercraft, motorcycles, ultralights, and lawn mowers! :o).Built in 3DS Max 7.0, and exported out as a 3DS file. opened, checked , and rendered in Maya 7.0 testing the export integrity. NOTE 3DS is an exported format so some smoothing will need slight adjusting once you import it as with most 3DS exports.
