Ignitech

Seeing as yer close, are you coming to the rally John?

Close to what? Certainly not close to speaking English as far as I can tell  :LOL:
 
When I got back to mucking around with my new ignition, the bike wouldn?t run properly. It turned out the insulation on the pickup wires was crumbling, causing short circuits all over the place.

During the repair, when I was tracing the wires I found that I had misread the workshop manual when working out the colour coding for the coils, when hooking up the Ignitech.

The book has:
left sparkplug labelled 1
right sparkplug labelled 2
centre sparkplug labelled 3

I missed the small print under the sparkplugs and read the numbers as cylinders 1, 2, and 3, with 1 being the left cylinder as you sit on the bike. All wrong.

To have the colour of the wires for each coil on my bike, match up with the book, I have to read the book as having the left hand side, when looking at the bike from the front.

On my bike, the coil wire colours are (when looking from the front):
LH ? orange. No. 1 in book
RH ? black. No. 2 in book
CENTRE ? green. No. 3 in book

What I call No. 1 cylinder on my bike (the left cylinder as you sit on the bike) has the black wire. The book labels the black wire as, RH cylinder, No. 2 sparkplug, and shows it connects to the front CDI.

Once I saw this I realised I had the Ignitech coil connections wrong, but as Cam pointed out earlier, it is a pretty smart box, and worked out what to do, in spite of me. I don?t think it runs any different now I?ve hooked it up correctly, but I only had one short ride before.

Afterwards, I took it for a ride with its new pickup wires, and ignition. The difference with low gear running is brilliant, the way it exited corners in low speed twisties was somewhat amazing.

I?ve got a bit of a backfiring problem to look at, that wasn?t apparent before, other than that, it?s going great.

While holding a steady throttle, about 3.5 to 4k revs, it?ll be making lots of small pops. Hard to hear sometimes. The sound is a bit like carby farts, but I?m pretty sure it is in the exhaust.
The backfiring isn?t real bad, and it doesn?t seem to affect how it runs, or do it all the time. I think I?ll go for a ride with the original ignition connected and take the same amount of notice as to how its running, maybe it was doing it before.

RGS harness - coil/cylinder 1 (left, when sitting on bike) ? black, front CDI
RGS harness - coil/cylinder 2 (centre) ? green, centre CDI
RGS harness - coil/cylinder 3 ? orange, rear CDI

Ignitech coil 1 ? Orange
Ignitech coil 2 ? White
Ignitech coil 3 ? Yellow/Black
 
I?m back. I have been fiddling some more, over the past few weeks, and the bike now runs great.

I re connected the BTZ ignition, and went for a blast, and it ran really well, I think the new pick up wires made a difference, but more importantly, it did not do the staccato, machine gun type back firing.
I played around with the beginning of the ignition curve, and the back firing was still there, but went away after the bike warmed up.

I then changed the base advance setting from zero, to one, and the back firing disappeared. I thought zero base advance was a bit strange, the Ignitech instructions say it could be anywhere from 3 to 22 degrees, and I never read of anybody else having zero base advance, when reading up on all the Ignitech info on this forum.

I did try a couple of degrees above zero when I first was playing with it, but it ran like a hairy goat, which I now put down to my crumbling pickup wires. I was changing, and trying things with an intermittent short before.

I moved the base advance to two, and I think it runs the best it has ever done. At the same time, I made up a setting with three degrees base advance, but I haven?t tried it yet. Quite happy with how it is now.
