Our full kit for the upgrade includes new coils from Rick’s Motorsport in addition to the ignition kit from Elektronik Sachse. Elektronic Sachse makes ignition kits for many vintage motorcycles. Rick’s has coils to replace most vintage bike ignition coils. Photo by Keith Fellenstein

Our project this issue is upgrading the ignition system on a 1977 Suzuki GS750 from points to Elektronik Sachse solid state ignition. Once done, we won’t have to worry about points and condensers any more and can just enjoy riding. This project is relatively simple, as you don’t have to disassemble anything more than the points assembly. A good set of metric wrenches and JIS screwdrivers are all you need to complete the project, along with wire crimpers and strippers, and some zip ties. — Keith Fellenstein

1. Our subject bike is up on the lift. It currently still sports the original-style points ignition. Not for long!

2. After disconnecting the battery, we’ll start the process by removing the points cover. Three Phillips type screws hold the cover on. This is a dry assembly, there should be no oil or fluid inside it.

I have installed a Electronic Sachse System on my Benelli 750 SEI. They sell a fantastic product, and despite a bit of occasional extra “fitting” required, highly recommended. The article is well detailed, but a few points: In step 43, your instructions suggest “Rotate the engine until the outer two cylinders are at TDC”. With the original ignition plate and advancer removed, how do you determine TDC? On my Benelli I had to open up the other end of the crankcase, mount a degree wheel, and fabricate a pointer....... Lastly, you should be clear that changing coils is just an interesting project. If they are working, why would you? The money would be far better spent on a new set of caps (definitely trimming a bit off the wires). Maybe a new set of Iridium spark plugs would have been a more useful spend?

A couple of thoughts here as in the tools needed start your article you noted a JIS screwdriver (Japanese Industry Standard) which is the only type of screw used on a UJM bike. Then in the article you refer to a Philips screw which they are not that type used anywhere on the bike. While it may be nit picking, unfortunately too many novices don't realize there is a difference and end up damaging the JIS screws with a Philips driver. Given the cost of the parts from both the electronic ignition seller especially the need to grind down the outer PCB board on that unit is well poor design at the least. It should be designed to fit exactly to the bike it is intended to be used on period. Anything else is shade tree mechanics at best, it appears the manufacturer is making a one size fits many models approach, which this one it doesn't fit well at all. There are benefits to the electronic ignition upgrade for sure, yet personally I would spend my hard earned dollars on something that fits correctly out of the box.
