I bought this.

If you buy the genuine outer rotor, generator coil, and other peripheral parts,

it will cost quite a bit, and I have decided not to buy used electrical products.

The one that caught my eye until the end was Modern Works' lightweight outer rotor.

The generator set is an incredible bargain at 5,980 yen.

It says to use a lightweight outer rotor because it puts stress on the crank.

Right? (ﾟДﾟ) It's in the notes for the GPX engine.

It seems that the original is almost the same as Takegawa's lightweight outer rotor.

It has many good points, such as a great throttle response and improved acceleration,

but the power generation is unreliable, which is a drawback.

If you make the outer rotor smaller, the generator part will also be smaller, so it's only natural that the amount of power generation will decrease.

I have no complaints about the current power generation, or the outer rotor, which seems to be a little lighter. *14.5V at 5000 RPM.

I'm satisfied with the idling, acceleration, and RPM increase.

The only problem is that the ignition is messed up, and it's strange to rev above 6000 RPM. I don't want it to go above 12000 RPM or anything like that. ε-(´∀｀*)ﾎｯ

So, this is Daytona's middle weight outer rotor.

It's lightweight at 680g and the power generation seems fine... and it comes with a CDI, so I think it should be fine...

But I don't know if it will actually run without problems when I install it...

Because this is also for Honda horizontal engines, and it's not a perfect guarantee for Chinese engines... I can't complain to Daytona because it's a wrong way to operate it.

If this Chinese CDI worked properly, everything would be solved...

(´・ω・`) sigh...
