I've started using the DSS electronic ignition system and it's actually an excellent quality item. I believe this is the 'Daytona' system made in Japan by Kokusan - interestingly they are the OEM manufacturer of the electronic ignition in my 1979 Kawasaki KZ1000 MkII.

Bryanj:
Kokusan made a lot of electrical stuff for many japanese motor manufacturers

Bryanj:
2nd for Mark(hondamans) system because i do so little mileage i live with the points as is but if i was riding more i would go with his.
He is that honourable that when a two year old system failed he replaced it evev though the problem was where the owner mounted it and managed to fill it with water.
Similar to the old sparkrite system for cars where it drops the current accross points to milliamps so no arcing or electrical wear, plus if it does go wrong a matter or minutes to revert to standard, unlike full ellectronic systems

"Similar to the old sparkrite system for cars" that's a good memory of those Bryan.

I've still got a Sparkrite fitted to a 1980 Rover V8 with single set of points for all 8 cylinders. Still works perfectly and has a switch so that you can isolate it and run just points or switch it to electronic without changing any hardware.  Works so well you can start it by hand hot or cold with the crank handle  ;D

They are just taking the timing from the points with a miniscule load across then,  then using an amplifier to switch a power transistor to run the coils.  The points really do last indefinitely with this method as all the loads are switched via solid state components.

Thanks for all of the insight chaps, there certainly seem to be some good systems and choices out there.

Ken has very generously offered me a solution to replace the mess on my bike and get me up and running. I think I'll need to take the time to look into Honda Mans system too, it sounds like a great compromise between the two.

I have plans to ride the bike over to the Netherlands and West Germany to visit some travelling friends once I've got the  bike roadworthy and the world has opened back  up a little more, so I'm working to the goal of making her ready for a 1000 mile trip after languishing in storage for all of these years.

Some parts are finally starting to turn up on the  doorstep so I need to get cracking. I've even picked up a 6L ultrasonic cleaner to do justice to the carbs when  I get around to stripping them. I still need to work out what the best service kit for my rebuild will be. Perhaps considering all of the required O-rings from Julie and then hoping that all of the internal components can come up like new in the ultrasonic...
