Which model H1 do they fit ?

I will contact them and find out

Have received the following reply, now waiting to see if they have any left in stock.

Thank you for your enquiry, we did manufacturer a ignition box that runs from the 12volt supply not the high voltage alternator widings, these often giving trouble. It could be used with the original triggers on many of these models.
I don't know if we have any stock of these so I will pass this on to the works for them to follow up.

I highly recommend Lake Services....their products are proven to work well on the Triple.

If I remember correctly.
The Boyer system would only work properly with a fully charged battery (13.8volts)
Below that it begins to misfire.
Unless this has changed I would steer clear

Got the following reply today about which bike they fit.

We can’t supply exact model designations for these bikes, but the following description, combined with the information sheet (attached) should help ascertain suitability.
The ignition unit is intended for installation by someone with basic electrical knowledge and a workshop manual.
BOX00246 is designed to work with H1/H2 series bikes that were originally fitted with CDI and CDI Magneto systems.
It utilises the original Kawasaki ignition pick up (pulser) coil/s, which should be connected as appropriate and in good order.
If the engine is fitted with an ignition distributor it must be disconnected as interference from its slip ring and brushes will cause interference to the unit.
On magneto models, the Kawasaki high voltage generator coils are also not used, and should be disconnected.
The system will operate with the original CDI ignition coils, but check for earth links that will require removal on some models.
Suitable new ignition coils can be supplied if required, only two coils are required, one dual output (Part No.COIL00008) and one single output (Part No.COIL00007).

I had a boyer on my71 h1a for 25 years and it was ok but as some one said you have to have a fully charged battery
