Hello has anybody experience with these coils on a 350 ypvs? Tia  |

Will these coils work with an ignitech?

Never seen them before
Basically any did is just a capacitor discharging hence the name
I'd be wanting to know the primary resistance reading but should be ok

The primary coil is about 0,7 Ohm.
With both these coils paralel it be 0,35

I have seen them before they are 50cc bikes not a 350 ypvs

Thanks Norbo
I found info that it can be used only on a 50 125 and 150cc gy6 scooter atv tao tao.
What is that? Chopstick driven?🧐

They look familiar to the light weight racing coils from Igni. I will ask Igni for the suitability on waisted spark on pv with dccdip1race.

Same coil as on my lads pit bike thing.
Ohms resistance rating is what you need to go by.
After that it's longevity is down to the build quality.

It is not easy to measure the primair coil resistance. Just measured it again. They are about 0,4 Ohm

Reply from Jiri from Ignitech :
Maybe is possible to use IC-CDI-F (22 EUR each) in serial connection (not parallel).
But I think there will not benefit compare to original double output ignition coil.

If you connect them in series you will half the voltage to each one
Don't think the Iggy or Zeel likes not resistor plugs so if you for coils with too low a primary resistance it would have the same effect

But there is another thing with these racing coils. The secudairy coil is one end connected to the spark and the other one to the common black earth. So if you serie the primaries one secundairy coil is not connected to earth. When i am going to test these coils i will run them with the primary coils paralel. That is the same as running the banshee coils I believe. |

Doesn't the Ignitech give you the option to fire each cylinder individually, so each spark has it's own coil, same as on a 3/4/5 cylinder bike??

Yes they do. But a dccdi1race with waisted spark is also supplied for rd350ypvs and 500
Today I received another email from ignitech.
Cylinder in BDC has not compression, so there spark occurs approx. at 1000 V. If spark occur - it is "shunt" (short circuit) for secondary winding of this coil. Coil is transformer, so that shunt at secondary winding will be transformed to primar winding (also shunt).
In compression cylinder will spark occurs at approx. 10000 V.
Serial connection function so, that non-compress coil is shunt and compress coil works. Non-compress circuit will eat approx. 1/10 of energy, compress circuit approx. 9/10 of energy.
Principle with one coil with two outlets is similar. Non-compress circuit make shunt at one coil output, compress circuit works at second coil output.
Parallel connection of coils will works, but non-compress coil will to eat bigger part of energy compare to serial connection.
I replied
Ok, thanks Jiri
But this is how the the rd350 original works.
Then is a 2 channel better I understand that.
The racing coils have common ground for both primair and secundair winding. When you serie connect both coils there is one secundair which is not connected to earth.
How bad is that?
