Tech Info
Light on fluff, heavy on the stuff that actually matters.
Ignition Basics
The stator makes power and trigger signals. The CDI decides when to fire. The coil steps voltage up high enough for the plug to jump the gap under cylinder pressure. When one of those pieces gets weak, hot, or unstable, the bike shows it.
- Weak stator = weak or inconsistent spark
- Bad grounds = mystery issues that waste time
- Wrong timing = lost power or broken parts
Timing Advance
More advance can wake up the midrange and top when the rest of the engine is ready for it. Too much timing for the fuel, compression, and load will cost you parts. That’s why the timing kits are built around controlled increments instead of random slotting.
- Blaster kit: roughly +3° through +7°
- Tri-Moto kit: roughly +5° through +8°
- Start conservative if you don’t know the current setup
Stator Health
A CDI can only do its job if the stator feeding it is healthy. Old insulation, heat cycles, and vibration kill ignition performance slowly. If a machine breaks up hot, drops spark randomly, or acts different every ride, the stator deserves attention.
