Hello there. First time posting here. I bought a kawasaki as my first bike a couple days ago.($250) It hasn't been tried or ran in 6 years. It has been garage kept all of its life. I cleaned the air box, replaced the filter, and lubed the clutch cable. New yuasa battery on the way. The spark plugs are rather black, but I have new ngk plugs on the way. I have a grunge brush on the way, as well as the solvents needed, as well as new RP oil (10 w 40). I have bought some carb cleaner as well as some RP gas tank cleaner. The tank was stored empty, and the fuel filter is clean. I cleaned all of the chrome with the aluminum foil trick.



Not for right now, but how can I repair that dent? It has a crease in it, but it seems like an airbag could relieve a lot of the dent. Thoughts?

Once I get everything, I am going to try to start it. Should I shoot PB blaster or WD40 into the spark plug holes to save the rings? Should I just shoot oil in there? Also, what am I missing? Thanks.

The dent, I'd ask around at the paintless repair places, as they have tools to work on the inside of the tank. I'd remove the sparkplugs, spray some PB Blaster in there, re-install the plugs & let sit for a few days.

Do this too:

Cleaning Motorcycle Electrics

Get some of the De-Oxit DN5 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. CAIG Laboratories - Home of DeoxIT® & Hand-E-Glove® is their website, and can be purchased at most electronic supply stores.

On the older Kawasaki's, and other makes, 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 DN5 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 response 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. If you discover the soldered connections at the switches are crumbling, I’ve got a repair procedure for this, just ask.

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 DN5 and then rubbing the inside of the fuse clip.

All battery cables must be clean and tight for maximum current transfer. Check the cables going from the Negative(-) battery terminal/post to the engine mounting bolt

Also the one going from the Positive(+) terminal to the starter solenoid and from there to the starter motor.

If any battery cable feels ”Crunchy” when flexed, replace it as possible corrosion is inside the insulation.

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.

Some people put the Di-Electric Grease on cleaned terminations/connectors, I don’t, as I’ve read/heard it can cause problems when it gets hot, actually insulating the connections, so the choice is yours to use or not.

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


“I spent a weekend going through every electrical connection and switch on the bike with a little scotchbrite pad and DeOxit - what a difference! Everything was brighter, gauge backlights, indicator lights, turn signals, I was getting a nicer spark, it fired up quicker, etc. Well worth my time. WELL worth it! “

Re: Cleaning the many and various Motorcycle electrics.
I used the De-oxit D-5 spray on all the electrical connections of my 78 Kz1000 that had sat for twenty years .

When I parked the bike in 92 I was starting to have troubles with some of the electrical system, but after pulling everything apart and giving it a spray , reconnecting the connectors and working them back and forth a few times, then gave them another shot of spray to wash them off before the final reconnection.

Everything still works perfectly and has for over 7000 miles this year.

I am extremely happy with the results , a lot of the connectors were green when I started and after the cleaning they looked new ( shiny gold )

I found the Deoxit D-series, D-5 spray in a 4 oz can at a big electronics store called Frys in Illinois, don't get the small cans at Radio Shack , they are different and meant for computer type stuff.

DeoxIT® D-Series

Trust MFolks , the guy's a true rocket scientist and really knows what he's talking about.

When getting a older motorcycle back on the road, you'll need many things replaced:

1. Tires: probably due to dry rot, since the contact patch on most motorcycle tires is about the size of a quarter(.25 cents), get the best tires you can afford. Tires should be replaced before every 5 years, as the Sunlight & Ozone affect rubber items.

2. Brakes lines & brake fluid; again, Sunlight & Ozone for the rubber lines, as for the brake fluid, most are water absorbing(Hydroscopic), and may have corrosion or rust in the brake calipers, or brake drums.

3. Engine oil; the old saying "Oil is Oil" does not apply to todays oil, as most car engine oils have "Friction Modifiers", to increase mileage, but it's harmful to the starter clutch, and the wet plate drive clutch(makes them slip). Get motorcycle specific engine oil, Shell Rotella is well liked here.

4. New properly gapped and correct heat range sparkplugs. When installing them, put on the first few threads, some of the silver anti-seize, to prevent galling of the threads in the engine(it also makes removal much easier next time).

5. Drive chain & sprockets, If there's any "Hooking" of the rear sprocket(the actual teeth will look bent), replace the chain, and engine and rear sprocket. The reason for that is worn parts, will quickly wear out new parts. The drive chain should not have rust, excessive wear, or missing rollers. If the bike has a centerstand, get it up, and with the transmission in neutral, try to spin the back tire, inspecting the rear sprocket, chain, and wheel for damage. Listen for wheel bearings making noise & dragging brakes.

About all I can think of at this time....

Testing Kawasaki and other brands of Motorcycle Ignition Coils For Input Voltage:

When voltage testing Kawasaki and other brands of Ignition Coils, the following needs to be done:

1. Remove the fuel/gas tank to access the coils.

2. Fully charge the battery.

3. Using a multimeter, set it up for VDC(Volts, Direct Current), range of 20.

4. Turn on the ignition switch and the run/stop switch to “Run”.

5. Put the multimeter’s RED probe on where the red or red/yellow wire goes on the ignition coil.

6. Put the multimeter’s BLACK probe on either the battery Negative(-) post/terminal or a good frame ground.

7. You should be able to see battery voltage at the ignition coil connection, but this depends on the current draw of other items in the same circuit.

8. If the tested voltage is down to 8-9 volts, you probably need to clean the many and various electrical connectors.

9. To check the spark output at the sparkplugs, use Ignition Spark Testers. Instead of grounding the sparkplug with the sparkplug wire attached, looking for a spark. This method puts the IC Igniter and ignition coils at risk of failure due to high currents, and possible internal shorting.

These bikes have a 5000 ohm, non-replaceable resistor in the sparkplug caps. They go bad from heat, vibration and age. New ones are available at most Japanese motorcycle stores, or through Z1 Enterprises, Inc. - Specializing in Vintage Japanese Motorcycle Parts, including New Old Stock & aftermarket parts.

It supposedly has new tires, and they look good. Brakes are solid, but I have yet cracked open the master cylinder. The rear is a cable into the rear drum. I have bought a grunge brush and a bunch of cleaning sprays, so I hope to get that going good. The only thing I am concerned about is that while I am in neutral, there is some clicking after a little turn of the rear wheel, and it is like that the whole way around. Is that normal?

The transmission is a wet clutch, correct? This oil will not work?

Best Oils To Use In Your Bike (Just My Opinion)

Engine oil : The commercial grade oils are clearly superior to the mass market oils. For the best protection in your bike or car, use Shell Rotella Synthetic, available at Wal-Mart in blue containers . For the best petroleum oil you can buy, get Shell Rotella T, Mobil Delvac 1300, or Chevron Delo 400, available at any auto parts store. On the back of most oil cans is a circular stamp with the certification. Avoid oils that say "energy conserving" in the bottom half of the donut. These oils contain friction modifier additives that could cause clutch slipping over time. All XXw-20 and XXw-30 oils are energy conserving, and should not be used in your motorcycle. Don't buy any oil additives like STP or Slick-50. Here's several listings on all about oil justifying these conclusions.

The Recommended Synthetic Oils :
Shell Rotella Synthetic
5w-40 Delvac 1 Synthetic
5w-40 Mobil-1 SUV/Truck Synthetic
5w-40 AMSOil AMF Synthetic (pricey, but it’s your money)
10w-40 Golden Spectro Synthetic
10w-50 Motul 5100 Synthetic
10w-40 Mobil-1 Synthetic
15w-50 Mobil-1 MX4T Synthetic

The best synthetics are: (in no particular order)

Shell Rotella-T Synthetic 5w-40 (blue container, not white), gallon at Wal-Mart.
Mobil Delvac-1 5w-40 (grey container, not black), gallon at Petro stations, gallon at Farm and Fleet.
Mobil-1 SUV 5w-40, qt anywhere.
AMSOil AMF 10w-40 synthetic motorcycle oil. (again, pricey)
Golden Spectro Supreme, (no price).
Motul 5100 Ester, (no price).

Mobil-1 automotive oils all contain small amounts of moly - about 100 to 200 ppm. This can cause clutch slippage in some motorcycles. I've only heard of this being a problem in Honda Shadows.

The Recommended Petroleum Oils

Chevron Delo 400 15w-40
Delvac 1300 15w-40
Shell Rotella 15w-40

The best petroleum oils are: (in no particular order)

Chevron Delo 400 15w-40 (blue container) gallon at any auto parts store, gallons at Costco.

Mobil Delvac 1300 15w-40 (black container) gallon at any auto parts store, gallons at Sam's Club.

Shell Rotella-T 15w-40 (white container) gallon at Wal-Mart or any auto parts store, gallons at Sam's Club.

Castrol 15w-40 (Green container) gallon at Wal-Mart or any auto parts store, gallons at Sam’s club.

If you live in another country, you'll have to do a bit of research to decide on an oil. Generally, any oil certified for use in a late model Volks wagon or Mercedes turbo diesel is a good choice. Another good idea is to go to a truck stop and ask the truckers about brands. Rotella is marketed all over the world, but in other countries it's called Rotella or Rimola or Helix Ultra, and the formulation may be a bit different, depending on local climate and preferences. It will likely also be a lot more expensive than it is here.

One last thing to consider is whether oil contains friction modifier additives. For improved fuel economy, most passenger car oils have such an additive. But the wet clutch in your bike doesn’t perform right with friction modifiers. Universal engine oils don’t have friction modifiers.

Be careful choosing diesel oils. Not all of them are universal. In addition to the API Service Category CI-4 PLUS for diesels, look for API Service Category SL.

Premium universal oils like Shell ROTELLA T Multigrade are formulated for heavy-duty performance, and your bike engine has some heavy-duty challenges for oil. For optimum performance, be sure your oil is up to the challenge.

JASO OIL SPECS:
Find an oil that shows the JASO-MA rating on the bottle; there are plenty of them available both dino and synthetic.

The ingredients in oils have changed over the years. For example, today's Castrol GTX oil (and pretty much all other AUTOMOBILE oil) is not the same as it was in the 1980's. Back then it worked great in KZ bikes. But, things have changed. Early AUTOMOBILE oils contained zinc phosphorus compounds (ZDDP) to protect engines from metal to metal contact. This was good for engines, but it was found to be destructive to catalytic converters. Consequently, in AUTOMOBILE oils ZDDP was virtually eliminated and replaced with different chemistry generically referred to as "Friction Modifiers."

These work fine and offer good protection for normal AUTOMOBILE engines. However, today's AUTOMOBILE oil "Friction Modifiers" are destructive to wet clutches. KZ bikes (and many other brands) have wet clutches. As a result of these oil chemistry changes a distinction needed to be made between those oils which are suitable for wet clutches and those which are not.

That distinction was documented by the Japanese Engine Oil Standards Implementation Panel (JASO). JASO developed a number of different oil specifications for different applications. The specifications that apply to 4 stroke motorcycles fall under the "4T Specifications." Within the 4T specifications the JASO MA class oils are specifically formulated for 4 stroke motorcycles with wet clutches.

Using oils that are not designated as meeting the JASO-MA standard may be destructive to KZ clutches. Here's a link that may be helpful:

I have a repair manual in the mail. I have read that this oil will not work. RP oil would cause issues with my wet clutch, correct? I guess I can find another use for it... :p

Going to get rotella tomorrow I guess, spark plugs will hopefully arrive tomorrow also...

EDIT: I guess this could all seem rudimentary, but I am just trying to get some stuff done before I get my book. Thanks for all of the help.

Sparkplug gap (what I use) is usually .028" to .031" checked with the wire sparkplug gauge. A flat feeler gauge may not measure the electrical erosion on used sparkplugs, so get a set of the wire gauges. You will also need some metric wrenches, sockets,1/4",3/8" drive ratchets and extensions. If you're not familiar with the electrical system, and need help if the previous owner messed with the wiring, don't be afraid to ask for help.

Thanks, I have a sundry of tools from dealing with my truck. I have done a lot to it, and now am attempting a bike...

There is one thing with the wiring. I was looking at it, and there seems to be two wires coming from the positive terminal. One of them goes to the rear (actually splits into two), and goes through an inline fuse. It feeds into the wrap for everything in the rear, but on a hunch, I would say turn signals. I would say it would be a chore to unwrap all of the rear wires and figure out which was which, but if it has to be done, it has to be done. It doesn't look oem, but is it?

These bikes usually have a dual filament bulb in the front turn signals, one filament for running lights, and the other for the turn signal. the rear ones only have a single filament, just for the turn signal. If you wanted rear running lights, you'd have to find RED lenses, as nothing amber should be seen to the rear.

Got my battery today, filled it up and charged it. All turn signals work, as well as lights. I was able to turn it over with a little help from carb cleaner, but found out that I missed the gasket on the oil filter housing. Tomorrow I will get new o ring, and hopefully have it running. Also need hose clamp for fuel line leak at new filter.


I replaced the filter, oil, oil filter, spark plugs, battery. Cleaned the chain, looks brand new. Bug and tar removed the fairings and tank, underneath and viewable portions. I put a little bit of oil in the cylinders before starting. Oil is Valvoline 10w 40 motorcycle oil, as parts store had no rotella. New spark plugs are correct part, but old were different part number, that supposedly is wrong. (Cross referenced multiple stores)

Rode it a little bit today. Just up and down my street. I was wondering how people back up and waddle with the bike, but then realized my front brake was siezed. Took apart the caliper, found a spider, cleaned it, and then realized that the real issue was the master cylinder. Took it all apart and put it back together. All of the seals were in great shape, and nothing really bad to say. Stretched the spring a bit so that it plunges all of the way, as it used to give out early.

Issue: The master cylinder will not give fluid to the line. Brake fluid drains through when the piston is out, but once the piston goes in, nothing comes through. I followed the book, and still an issue. It gurgles when I release the brake, which means that it does bleed through the hole in between the two spacers. What could be the issue? All I can think of is that the seal covers the hole, but it is in the correct location...

I'd replace the brake line, as they've been known to swell, and restrict fluid flow. Also, inspect the master cylinder, as there should be two(2) holes in the bottom, for fluid to pressurize, and release.

I'd take wooden toothpick, and carefully open up the blocked passage. One of those should have fluid to the piston when the front brake handle is squeezed, and the other will have a relief, when the handle is released. With low fluid, you can see a small "Squirt" when this happens.

Well, to be honest with you, before I took the cylinder out, I found the right size drill bit and got everything out of the hole that is currently cleaned. Thinking the same thing for the other hole, I started to hand drill it out. However, I started to see fresh metal, so I stopped. If it were factory, It must work...

(all drilled by spinning with fingers.) I see a squirt when I release the brake. Should I see it some other time?
