Performance CDI and high voltage coil in order to have strong ignition with timing that changes with rpm's which improves spark strength for more consistent combustion (cleaner smoother running) and gives better power at all rpm's and allows it to rev high without as much engine vibration or chance of knocking.

Specifications
•True 2 stroke CDI designed for China engines
•Timing advance & retard curves
•Twice the spark power
• (especially necessary for higher compression)
Adjustable timing curves (4 settings)
•3" x 2" x 1" enclosure
•High power ignition coil
•High performance ignition wire with spark cap

Benefits
•ignition retard at high rpm's allows
 higher rpm's without engine overheating
•Timing curve works with expansion chamber to extend power band
•Faster combustion resulting in more engine power
•Less engine vibration at high rpm's
•More reliable than stock CDI/coil
•Easier starting
•Smoother running
•More torque and horsepower
