Morning all. I know a couple of you are following this, and if
this is you , and you have looked at the Daniel Creaney CDI
performance parts YouTube video channel, you will probably know
that there is not a lot of easily accessible information on it.
He talks through things very quickly and assumes you know
things. Also the kits have changed slightly since some of his
early videos.
The system does not seem to be rocket science but I thought an
un-boxing video might help anyone who goes down this path after
me... (Before watching, see erratum below)

Interested to see where this goes Jim, thanks for explaining it.
I put CDI on my hard to start V8 and it transformed it, instant
start, smoother idle and instant response when you floor it !

I now have to add an erratum to the above video. It seems
(somewhat illogically to me) that the coil green terminal is the
earth and the black terminal is the feed from the the CDI unit.

Well, I have eventually plucked up the courage to go into the
sub zero, unheated garage and spanner the engine out of the BSA.
The CDI kit fit pretty much straight out of the box with the
exception of having to make a small bracket for the coil as the
one supplied fouled the exhaust a bit for testing. (not a
problem if I had it in the cyclekart with the proper exhaust)
So the first start took a bit of doing as the engine has been
sat for ages and I think I had a loose sensor wire. That sorted
it went on pull 3 and went well... So I shot a small video of
the second start after a couple of minutes of warm up for this
thread...

It pains me to say it but that looks very much like a GY6/Pit
bike ignition module. I did wonder if one would do the job after
you bought it, so would have been too late to save you money
anyway.
They come in various "flavours" including AC ones which might
run off a charging coil fitted to the engine:

True, looking at the bits, the CDI is about a tenner, the coil
about the same, the wiring and harness say a quid in bits. BUT
the flywheel sensor is bespoke. On his website, he suggests that
it is programmed with his own easy start programme. As I can't
see inside the box, this is hard to verify. As I said at the
start of this thread, I may be wasting my money. I doubt I could
have replicated an accurate sensor for the flywheel so perhaps
not?

Fair point, a sensor is the only thing that doesn't show up on
the search, and I think it's integral with the alternator coils
on a gy6 engine, and NO I'm not taking mine apart to find out!

Thanks for the offer of the box Chris, I was not trying to be
ungrateful. If I ever fry this one, I would try an eBay one
before going back to CDI performance parts. I do think that the
guy deserves credit for trying to market this, the GY6 engine is
reliable and runs well with good power for a small block. Even
if it is just the same box, the firing point should place less
stress on the engine especially at higher revs which places less
strain on the internals. Time will tell. Experimentation is
sadly what I always do. I just wish I had a Dyno :)

You didn't come over as ungrateful Jim, bouncing things around
frequently gets results. A bit more research has turned up
trigger sensors so they are available. I'm probably going
electric with the Renault, but if that doesn't go to plan I may
end up playing with a GX200.

Thoughts on the CDI kit so far…
Bearing in mind I still need to test it at an event, and the
conversations that I have had here about it.
1.
about £30 all in Except the Pulse/ Stator/ Trigger sensor which
has been made bespoke for the GX200 type engine. I cannot track
down a single trigger sensor with the same plug and wiring. A
GY6 sensor might do (another £8 eBay purchase but it is an
unknown). Another big unknown is if the internals of the CDI
unit have a map to suit the GX200 or it is just a standard four
stroke single cylinder map as for the GY6 engine. This said, the
$100 (down to $80 on thanksgiving, Xmas, labour day, black
Friday) plus postage – which if you choose land mail takes
literally months - still seems reasonable to me given the
unknowns of trying to create my own and adapting a sensor. If
you do go down this route, budget for a rechargeable battery,
charger and battery holder unless your system already runs off a
battery.
2.
motorbike than a lawnmower now – yet to be tested in real life
yet.
3.
put and the sensor moves. No hitting the flywheel nut with a
hammer or levering, no need to lock the shaft to apply the
correct torque. – I like that.
4.
above) but the plug showed that I had retarded it too far, two
more adjustments to the timing and the plug is the right colour
and it doesn’t spit flame on the over-run. I don’t want to add
too much advance as this kills the torque low down, and torque
low down was my initial aim rather than power at the top end.
5.
they don’t vibrate out – an easy job. I will mount the CDI box
on the cyclekart body, strap and tie the wires and cushion it to
stop vibration killing it.
6.
battery, at £10 off eBay, I think it will be worth it.

7.
stuff like a klaxon 😊
I am happy so far with it, the metal the sensor is on is soft, a
good flat washer needs to be used under lock washers as lock
washers cut up the surface. Gapping does not seem too critical
either.
