15 Deg 4-Cycle Mount System - American - Burris revolutionized the 15 degree 4-cycle mount system with the best the industry had ever seen. Our design has a three point slotted mounting of the slider to the base allowing for instant engine repositioning as well as a more structurally ridged package. Every critical surface has been machined to insure fit, function and performance. The 15 degree angle of this mount gives you the necessary clearance for either tank to tire or carb to tire for both flat head and OHV applications. We also know that looks matter, so to give your Burris mount that distinctive look, we black anodize and laser engrave each mount with the Burris logo. Superior quality and craftsmanship is what we pride ourselves on. Applications - 5 hp Briggs, Animal, World Formula, Yamaha YF200 R1, Honda GX160 & GX200, Tecumseh Stars and all F200 engines
