pistons are of a cast design, they are recommended over
forged design in most 2-Stroke ATV’s.
Sizes:
Generally STD thru 8th over in .25mm increments.

Ignition
Rewinding: As ATV stators get old or exposed to the elements
their power output begins to breakdown and weaken the
spark going to the engine or in some cases causing complete
electrical failure. When this process begins to happen
your engine will lose powerand start to run inconsistantly.
Rewinding
the stock ignition gives a solid alternative to purchasing
a new stator at a much cheaper price.
Lighting
Coil Output Modification
Lighting coils are rewound to put out additional lighting
power. This makes upgrading your lights to higher wattage
an option.
