I heard praytell that there is a simplified wiring diagram on rexs-speedshop.com but i couldn't find it for the life of me.
I was able to find these simple diagrams - https://www.flickr.com/photos/bcm-blog/sets/72157615127432489/
couple questions; In the diagram, they keep saying magneto. Do they mean that as the charging system? In my world a magneto makes spark for an old harley.  Also, are all sr500's a CDI ignition? mine is a '78.

thanks!

The mystery box is the stock VM34SS accelerator pump. Yes, the bike runs a self-exciting coil (kinda like a magneto), so you don't need a battery to have spark. Downside, one of the coils is a very fine wire 300 Ohm coil prone to shorting out, which means you end up with no spark below 2000-something RPM. (That's when the other coils kick in and produce the electricity for the ignition.)

Unfortunately for SR500s, you simply speak the wrong language, if you want support - time to brush up that German, but google translate will help you through the worst.

In order to bypass the stock induction setup, there's a so-called two-wire setup to check out the rest of the electrical system:

That being said, if you need parts, look into the direction of http://www.kedo.de

And yes, the SR500 has always been CDI driven, you can convert it to points, if your really wanted, but that's only possible, when you still have an older set of cases, which still has the casting pre-drilled for the points shaft and gear. Plus you will need a XT500 clutch-cover and points-setup. (Some german racers use that in the Grab the Flag Classic 500 series, aka. SR500 cup (www.grab-the-flag.de) and because you will surely wonder about it... tuning is rather sophisticated, with the best bikes running around the 50 to 55hp (at the rear wheel of course) )

If you need info on hot-cams, short stroke conversios, different carbs, bigger valves, altered combustion chambers... well, I'll keep an eye on this thread here.

Cheers,
Greg

Der Nano, my man! That diagram is perfect! thanks for the help, brother. I'm going to give her hell to get running this weekend. I'd really like to know what state the engine is in before I proceed fixing anything else.

Hurco, I'm in the Akron/Canton area.

That makes sense.  If that is what it is, then there should be two fuel lines - one from the tank and the other to somewhere on the carb where it discharges.

Man, I wish my swingarm was Motolanna. They're real nice. Mine is less elaborate and uses the stock chain adjusters.
