Honda C-Series motorbikes that have 100cc engines such as Astrea Grand, Legend, Supra, SupraX, Supra Fit, until now the newest releases are Revo, FitS and FitX. The motor engines are basically the same, but the Astrea Grand, Supra and SupraX engines have shorter piston handlebar lengths, shorter centric chains than other C-Series motorbikes.
The ignition system already uses AC CDI, on C-Series motorbikes the ignition system is alternating or AC.
Ignition for a standard motor occurs
• At low RPM (1,000 - 3,000 RPM) spark jumps at 8 - 15 degrees before TDC
• At high middle RPMs (4,000 and up) the spark jumps at 25 - 30 degrees before TDC
why does a standard motorbike pop sparks 8-15 degrees before TDC... this is possible because of the nature of the fuel/octane and the compression in the combustion chamber used.....as we know standard motorbikes use premium octane fuel 88 (combustible) and compression between 8-9: 1 ... so it only takes a narrow degree to burn premium fuel plus low compression which further supports the combustion process faster at (RPM 1000-3000)
but entering RPM 4000 and above the angle of the sparks explosion changes to 25-30 degrees before TDC is possible because the engine speed is faster and the "compression ratio" is different from low RPM
how can we upgrade this ignition degree.?
manually it can be done by sliding the pulsar pick up (the protrusion on the magnet) but of course using this method requires high precision so that the results are accurate....but this method is the cheapest method...therefore until now this is still a lot of people who apply it
but if you want a more accurate one, of course, use a CDI that can be programmed...which is widely available on the market...but the price is pretty decent.
If through the CDI the program is clearly very accurate, we don't need to bother changing the ignition level... because it's already available, so just click.
hopefully this is useful, greetings are healthy, LM CHANNEL.
