Yamaha R-3 Undercut Transmission:Undercutting is one of the most highly regarded modifications for race motorcycles. Many manufacturers do not undercut their transmissions at the factory. Undercutting involves the modification of the drive dogs and slotting to precise angles. Creating an interlock of the gears under acceleration,virtually eliminating the occurrence of an involuntary gear jump. Most drive dogs from the factory posses a 0 degree back cut, producing rounded gear corners under normal wear, in turn creating involuntary disengagement. Mach Modified under-cutting service can precision cut your transmission to perform at its most accurate and true level of performance.                                                         Allowed in MotoAmerica
