NEW BIKE, first KZ 1981 csr 650 19000 original mi

Your bike probably needs to have all the electrical connectionc cleaned as it's a 1981 model:

Cleaning Motorcycle Electrics

Get some of the De-Oxit electrical contact cleaner and figure on spending a good day going from the front of the bike to the back. It’s a plastic safe cleaner/preservative. www.deoxit.com is their website.

On the older Kawasaki's, a majority of electrical connectors are inside the headlight housing requiring removal of the headlight, then the fun begins.

Do one set of electrical connectors at a time to avoid mixing up what connects to where. Usually disconnecting, spraying with De-Oxit and reconnecting is about all you'll need.

However, when encountering the green crud of corrosion, a brass wire brush may be needed on the pins you can reach.
Some 400-600 grit wet and dry sandpaper strips rolled into a tube should reach the male and female pins in the more difficult to clean connectors.

Smoker’s pipe cleaners, cotton swabs and wooden toothpicks work as cleaning aids.

Really small electrical connectors may require the use of a welders tip cleaning tool assortment.

Most pins in the connectors are coated with a thin plating of tin, and others may be nothing more than copper or brass.

If moisture is added, the resulting corrosion lowers the voltage/current being carried causing dim lights, slow engine cranking, slow turn signal responce and lower input voltage to the ignition coils resulting in weak spark.

The left and right handlebar switch pods will need attention too as they have circuit functions like turn, horn, run/stop, and start.

Usually a spritz or two with actuation of the switch is about all needed for these switches unless corrosion is detected and then careful disassembly is required.

The ignition switch may or may be not sealed to allow spraying the internal contacts. I urge caution if attempting to open this up as springs, and ball bearings may fly out never to be seen again!

If your bike has the older style glass tubed fuses, I suggest replacing them as vibration can cause internal failure. AGX is the type used, and most auto parts stores can get them for you.

Clean the fuse holder clips, looking for signs of overheating(discolored insulation, signs of melting),
I use metal polish on a cotton swab, followed by spraying another clean swab with the De-Oxit and then rubbing the inside of the fuse clip.

Each "Bullet Connector" will have to be sprayed to ensure good connectivity, especially the ones going to the energizing coil of the starter solenoid.

The alternator output “Bullet Connectors” are usually behind the engine sprocket cover and will need inspecting and cleaning too.

The turn signal light sockets will benefit from a spritz from the contact cleaner along with the tail light/brake light socket.

Some brake light switches can be sprayed on the actuating rod, with the spray running down inside to the electrical contacts, others may be sealed requiring replacement if the switch is intermittent in operation.

I think I've covered about all of the electrical systems on the bike.........

well, if you know anyone that wants them. I'll do an even swap.

i saw a bike on here, I don't know exactly. i'm actually thinking that an all flat black cafe cruiser might be cool. powder coat everytihng?

great looking 650

Hi Torry, Great looking bike and nice price to pay for a bike like that. Welcome to the forum.
Seeing that you are a mechanic, I'd make only one suggestion, and that is to get a Kawasaki Factory Manual. The others are alright, but the Factory manual has more info than the others. A good carb cleaning with a fuel filter is in order if the bike has been sitting for a long time. I also have a 650 E which I just love to ride. A polished up,clean vintage bikes like ours, always have people looking. The bikes are not hard to work on and a zillion parts are still available. Good luck, and make it look new. Check out the KZ650.info forum, I belong to both. Bob

Nice find. I also just picked up an 82 CSR. I plan to BoB mine like this

It should be an easy transformation. Just a little cutting and welding on the frame, cut the seat pan down and reupholster and a set of flatter non-pullback bars. Reattach the backlight with some angle iron and make a plate holder. A set of mini led turnsignals and a neat little jumping spyder is born. Yours might be too nice to do this to. I also love a nice stocker too. Whatever you decide good luck.

replace the Fr Br mc? what the fuck? don't know what that is. Turn signals, ok, frame grip, got it. What kind of headlight upgrade.

Guessing Front Brake Master Cylinder.

But might be Frik'n Broomstick Motorcycle. :lol:

Good Fortune!
