TICKLING BARN25 december 2025 om 22:54 #831750Hi Joe,
I don’t know if that coil and CDI will work together. It would be great if they did, and we’re all curious about that, because a Curf, wow.As for turning the ignition coil on a lathe, it seems difficult to clamp. Maybe it would be easier on a distribution table on the milling machine.
On the lathe, I would use an aluminum insert because coil iron is soft and benefits from a sharp insert.
A contact point flywheel only has poles and isn’t designed to provide the correct timing with a pickup coil, like an electronic flywheel does. It only provides an alternating magnetic field to generate current for both the light and the ignition coil. The contact points provide the timing.
But it’s certainly worth a try. I’m not familiar with the coil you’re using, and this whole idea is new to me. You could turn the inner diameter of the soft magnetic strip from the contact-point,s flywheel bigger so you wouldn’t have to adjust the coil.
I’m very curious to see how this experiment progresses. 🙂
Edit:
I have to say I’m a bit disappointed with the Curve. It should idle at 0 degrees and start to drop at around 7,000 rpm for fast cylinders, and should top out at around 10 degrees at 12,000 or higher.
But hey this is better than a straight line.

My friends have also been using the stock us flywheel and the kinetic flywheel and the kinetic internal coil with the hpi cdi box for a more aggressive ignition curve. Those boxes don’t use a pickup coil they fire from reverse magnet polarity. So it fires twice per revolution vs once per revolution like an ignition with a pick up coil.
I clamped the old case in a 4 jaw chuck from the inside to get it true to the machine, and turned the coil down with a external thread tool because I had a new insert for the bar. It cut great, I didn’t want to mess the coil up with the interrupted cut.

When doing this you have to set the timing on the bike without the woodruff key, I lap the flywheel to the crank with valve grinding compound to keep it from slipping. Currently I have 2 bikes with the kinetic flywheels and the parmakit cdi boxes. I was curious about going this route since the flywheel is 100g+ lighter.
euro points flywheels


kinetic flywheels

😎
Where exactly lay those 2 reverse points to make shure where the ignition must come fore the spark plug at the ride moment ?
And lay those reverse magnet poles 180 degrees (opposite) on the turning circle ?
And also a spark just before bottom dead center ? (not shure that wil work)Is it working yet with the CP flyweel ?
Succes
TICKLING BARN1 januari 2026 om 19:11 #832053so if I read it correctly then I can use a tomos bobine/cdi 2 wire and connect it to my berini coil and use the berini flywheel to get a spark?
