Manual Cam Chain Tensioners : manual cam chain tensioners are designed to replace the automatic and hydraulic tensioners on high performance engines. The automatic adjusters can back out when the throttle is closed suddenly at high rpm. This allows the cams to go momentarily out of time, and can result in bent valves and/or serious engine damage. Hydraulic tensioners have a tendency to put too much tension on the chain guide under high rpm/high oil pressure conditions, resulting in premature wear.

Kawasaki EX300 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
