Hi all

I am considering upgrading my standard Z1B to an electronic ignition system but not sure which way to go. I want to replace the whole lot including coils. Research I have done so far points to at least three systems. I also like the idea of being able to remove the current original centrifugal ignition advance mechanism.

Dyna S (uses existing centrifugal advance I think)
Dyna 2000 computer programmable
Boyer Bransden Kit 00288

Any views welcome on what you have and why. Also are there any other systems out there?

cheers and thanks in advance

Dyna S if its for a standard road bike , no point in using Dyna 2000 unless you want advance/retard and such. I have Dyna S on my Z and Gs1000 both very good and easy to fit

Thanks very much for prompt reply. Any views on the Boyer Bransden one? Am I correct that the Dyna s retains the mechanical centrifugal advance gubbins?

don't really know anything about boyer, Dyna S I would go for only three wires easy to install. Suzuki performance spares have all the dyna range in stock and are good to deal with

Make sure your electrics are good , Dyna S does not like extra Voltage

yes the Dyna S uses the standard advance bob weights,

I have the Dyna s on mine with the coils and Taylor leads and can recommend it

Boyer works OK - but a bit less rugged as it has lots of "bitz & bobz" showing on a flimsy circuit board

How very true. I have had 2 dyna's pass out on me. One had the 1/4 circuit fail and the other actually melted whilst riding with smoke billowing from the points cover.
Keep your battery in tip top condition. They don't like tired batteries

ive had the bransden s 2000 on mine for some time, blumin thing has never started

Thanks for your advice so far, I went ahead and bought the dyna s and some new Ignition coils and DW600 supressed ignition leads. on trying to fit coils, I have come across some of issue I would like to run past you as the instructions are not very good.
First issue is that the mounting 'core' of the dyna 3o ohm coils is thicker than the one currently fitted so the bolts are not long enough to re-mount them on the frame, I will buy some 45mm long 6mm thread and that will sort that.


Second issue is the low tension wires one of them is only about 1mm away from the spacer. So I have put the earth wire in that position and hope it doesn't cause a problem, difficult to see on photo but look at the yellow / red wire


Third issue is how to fit the connector on suppressed HT lead as it just seems a load of threads, do I strip it to the black core or to the threads and then just fold it back under the crimp?


Any help greatly appreciated

WATCH FOR THE LOW TENSION WIRE SCREW SHORTING ON THE MOUNTING POST

Hi Pigford

Yes that is one of the things I am concerned about. But apart from ensuring the low tension lead near the post is the earth wire so I am assuming it wont matter if it shorts, I could put some insulation tape around the post but neither seem an ideal solution to me?

Sits very close....I put insulation around the front post and smeared it with silicon grease to keep water out too

Agree with Mark about the Lt shorting to the post i used a piece of heatshrink insulation on the post and covered the terminal with silicon,yes you do just fold the core back and crimp,have used the set up you have selected a few times and found to be very good make sure you set up with a strobe though
