I am finally able to start puting my 500 unit together. The engine is from a 70 T100c and it is completely taken apart in my garage.

I know there are a lot of options for ignition systems (points/digital) and electrical systems(battery/cap). I looked around on google and I haven't found anything to valuable.

I really would like to know what my options are.

Since this is a complete and total rebuild, I really have the option to take any route I want.

I have accepted the fact that this bike is a money pit, and that the 20$ here and 100$ here will add up to be more than a new t100 would cost me.

So, does anyone have any information about the different options they could send me? or do you have any advice?

Two basic avenues are keep it stock, with new components, or go for upgrades/non-stock parts.

Stock - points/condensers/coils for your ignition, and stator/rotor/zener/rectifier/battery for the charging side.

Upgrade - Boyer electronic ignition w/single coil for the spark side and Sparx uprated charging system, which is a stator/rotor and regulator/rectifier box. Oh and a little battery because the Boyer needs it. This cleans up the charging side considerably (fewer parts AND higher output). The ignition is fixed/doesn't have moving parts to wear out either.

The points argument is that you can always fix them on the side of the road with a hammer and baling wire. The counter to that argument is that you don't have to fix a Boyer.....

Are you saying that the Boyer units have never failed in service??

I still like the magneto option.

Thanks, for the info.

So let's say I wanted to go the magneto route. What would I need to keep? What would I need to dump? What would I need to buy?
i run a joe hunt mag on my bobber, never misses a beat, you can still keep the alternator and run a boyer black box for your lights doing away with the battery

So let me see if I understand this:

If I go the magneto route, I can get rid of the zener diode, rectifier, and coils. But I will need to keep the stator and rotor for the lights.

Then with a boyer black box (is this the same as a mitimax?) I can ditch the battery and if I want to upgrade the lighting, I will need to get something like a sparkx high output alternator.

or am I still lost?

if you go the mag route, you dont need ignition from the alternator.
if you want lights n stuff then you need a power source, so, keep the alternator but if you use a boyer powerbox (or similar) you can ditch the zener, battery and regulator.
make sense?
