Can CDI increase speed?
That scooters run exactly 45.000 km/h. So, if your mechanic has a “better” CDI, it either doesn’t actively limit the max. RPM, or it has a better timing at higher RPM, allowing more power output and hence top speed. Yes, stock CDI limit the power.
Are Honda CDI boxes interchangeable?
Because ignition characteristics (particularly timing) vary widely across vehicle models, there’s no one CDI box that can cover them all. The CDI must be matched to the engine that’s being worked on. The CDI boxes in these systems are not interchangeable.
What does a high performance CDI box do?
The “CDI” regulates your engine timing and also controls the spark intensity of your ignition system. A high performance “CDI” will advance the engine timing allowing for higher low rpm torque and higher top end speeds. The installation process is simple and the results are instantaneous.
Can you run a bike without CDI?
You need a variable spark timing anyway. To do this without a CDI the points have to be mounted an a self-advancing plate that rotates when the revs go up.
What is the effect of racing CDI in motorcycle?
The stock CDI would have slower charging capacitors with a lower max RPM, while “racing” CDI would have faster charging capacitors and a higher max RPM. You won’t notice a difference at all unless you push the engine to the rev limit, assuming your engine can reach the higher rev limit allowed by a “racing” CDI.
How do you take the rev limiter off a scooter?
Extract the limiting washer from the variator system. The limiting washer is positioned around the front pulley wheel, and in most scooters it can be removed by hand or with a pair of needle-nose pliers. Reconnect the left pulley wheel and replace the variator case faceplate.
How do I know if my CDI box is bad?
Symptoms could include misfiring, dead cylinders, backfiring, bizarre tach behavior, and countless other things related to how your engine’s running. The problem may get worse as the bike warms up. It might not even hold low revs at all.
What is Honda CDI?
Capacitor discharge ignition (CDI) or thyristor ignition is a type of automotive electronic ignition system which is widely used in outboard motors, motorcycles, lawn mowers, chainsaws, small engines, turbine-powered aircraft, and some cars.
Does a CDI box control timing?
In addition to dischargin’ those capacitors, the box may also influence your rev limit, timing advance, and other variables related to spark, but that’s it.
