dependable sportster?
Yes it can be done. Not difficult. Swap out the points etc, swap in the electronic ignition unit in the same place. May need to replace the coil as the resistance needed will be different. Also may be a need for different spark plug wires. And reset the ignition timing.
Lots of guys including myself use Crane Cams Hi-4 single fire. Other good brands available also - see what others say. Single fire is a definite plus over dual fire or "wasted spark" systems.

The Crane Hi-4 complete kit consists of the module, the coil, and the wires [and the instruction sheet, package of screws, etc]. You can also purchase the parts separately. And you can mix the Crane module with other brands of coils and wires - just have to use stuff with the right specs. I assume other brands to be similar.

The only problem I see is that when the s&s carb is put on then there is no use for the voes switch and they are saying that you need that switch for the new daytona to work. Will the crane still work without that voes switch Thanks
I am not familiar with the S&S carb. I assume that "there is no use for the voes" means that there is no vacuum port on the S&S carb. This is easily fixed.
Drill a small hole in the intake manifold and insert a short [1" or so] piece of fluted brake line, flute facing out. Any convenient place will do: central location, avoid interfering with mounting bolts, add a little JB weld on the outside, do not have it stick in too far as it would interfere with flow. Attach the vacuum line between this new port and the VOES.
The flute is just to help hold the vacuum line on.

The Crane will work without the VOES, but the bike will run better with the VOES.

Also Daytona will work without VOES as Crane but it uses only one advance curve.

Maybe that is why they put points in the bike instead of keeping the orig electronic ig on my early 84 bobber. It does have a S&S carb and there is no Voes switch on her. Does the bike run better with one or not ? Thanks
VOES = Vacuum Operated Electrical Switch. It senses change in vacuum in the intake then the EI unit adjusts ignition timing to suit.
