Ignition Coil With A Detachable Ignition Wire?

[jaan]

The Motoplat ignition coil of my Montesa has a fixed wire from coil to spark plug.

Any ideas on a good ignition coil with detachable ignition wire?

My Motoplat coil is thirty years old and it's wire is worn out. I'd need a longer ignition wire than Motoplat coils have.

Hi Jaan,

Not 100% sure what you mean here, but I think you are referring to the High Tension (HT) cable that attaches to the spark plug. If this is too short, then you can easily use another piece of copper HT lead and attach it with a tight fitting sleeve, usually a piece of an old plastic breather pipe will do, make off the ends flush and the spark will jump across easily - you can always cut off the head from a long self tapping screw and sharpen the other end on a grinder then insert this into either end of the HT leads to make a physical join - not that it is so necessary. The old Motoplats were a good coil, I haven't found a good replacement mainly as I have a spare Motoplat just in case! I guess you could try an old Japanese 6V HT coil from an early bike. I have experimented with fitting up a Kokusan 2 map digital ign system to my 352 Bultaco, not quite finished - need more time and less work. But this is a bit extreme I guess, I just had a spare system in the garage (flywheel/stator and coil).

Bye, PeterB.
