Hi, Js92039 ask 10 different riders and you will get 10 different answers. All oil is certified by the Oil Gods to perform under specific conditions for specific applications and any oil is better than no oil and if you're in a bind diesel oil works just fine. If your engine is air cooled never run automotive oil because normal motorcycle cylinder head temperatures run much hotter than water-cooled cylinder heads, make sure the oil is designed for motorcycles. Your owners manual recommends a specific type of oil that is designed to lubricate the engine parts to withstand the normal driving conditions the motorcycle was intended to be used for, end of story. Now for an analogy, your cars owners manual recommends using 87 octane fuel to power your engine for maximum performance and it does a wonderful job of achieving that goal. But you say 92 octane is better because it has a higher number and is more expensive, well guess what your car will not run any better and there are no long or short term benefits from running a higher octane fuel bottom line your car doesn't need it. Same thing with oil sure they make lubricants that can withstand the temperature of molten lava which you would need if you were planning to drive into an active volcano, don't waste your time and money on snake oil just use what your bike needs and your manufacturer recommends and nothing more. The oil weight grade is for ambient temperatures you expect to drive in between oil changes 20w50 covers 80% of all driving temperature conditions if your looking for a better oil that works in all temperature conditions, buy a Synthetic in the same grade from a reputable oil manufacturer I personally recommend AMSOIL just because they were the pioneers in synthetics and their load test numbers for wear put them in a class all by themselves and you can go longer and further in between oil changes. It's a little hard to find in stores but easily available online otherwise Mobil 1 is my second choice.

Is the bike locked up? Did the piston melt into the cylinder head?

If so you need to free up the piston to release the cylinder head.

You could try a little penetrating oil on the piston ring area and some heat. Then a wood stake and a mallet with a couple solid hits might unstick the rings.

Of course, after that...the head, rings and probably the piston are all gonna be scrap! Which they are anyway if the melted together right?

This is a link to your bikes online parts list from Kawasaki. You can at least get part numbers for replacements if needed.

Good luck and be careful!

Not really a big job here.
  • Take the sprocket off
  • Take a medium size hammer and screwdriver and punch the outer rim of the old seal towards the shaft. The idea is to deform the seal so you can gently pry it out without damaging the case.
  • After removing the seal just clean the case, lubricate the rubber seal and slide in onto the shaft and into the casing.
  • The seal needs to install evenly. If you can, use a deep reach socket, (just a bit smaller in diameter than the seal), to go over the shaft and mate with the seal.. Tap the socket with a light plastic hammer to seat the seal.
Remount the sprocket and chain and go for a ride.

Please rate this solution. Thanks!

Hi, Dcscccjc and the usual suspects are:
1. Fuel tank empty.
2. The fuel tank has old dead gas.
3. Fuel tank bottom contaminated with ethanol sludge, dirt, water, rust, etc.
4. Fuel supply valve/petcock turned off.
5. Fouled spark plugs.
6. Engine flooded as a result of overuse of the choke.
7. Vacuum hose to the fuel supply valve/petcock disconnected, broken, cracked, or pinched.
8. Fuel valve/petcock or filter clogged.
9. Fuel line to carburetor or throttle body pinched, kinked or blocked.
10. Carburetor float stuck.
11. Fuel injectors clogged.
12. Fuel injectors stuck open.
13. Quick disconnect check ball stuck.
14. Compression below 75 PSI.
15. A stuck-bent-burnt valve.
16. Improper valve clearance (too tight)
17. Severely discharged or a damaged battery should have 12.5 volts or more and be able to pass a proper "LOAD" test if necessary, you may have a cursory reading of 12.5 volts or more but little or zero amperage the battery is faulty and must be replaced, AGM batteries fail in this scenario more so than lead-acid batteries.
18. Check battery terminals for damage or corrosion, check the battery cables at "BOTH" ends for loose, corroded, or broken connectors, "INSIDE" and outside the cable harness, perform connector wiggle test and check cables with an ohmmeter if necessary.
19. Loose or corroded wire connection at the coil or plug between ignition sensor and ECM module.
20. Spark plug cables in bad condition and shorting check for spark leakage in the dark, cable connections are loose or connected to the wrong cylinders.
21. Ignition timing incorrect due to a faulty ignition coil, ignition module or MAP, CMP, CKP, O2, TPS, ETP, IAC sensors.
22. Faulty neutral, clutch, kickstand safety switch.
23. Faulty fuel pump or fuse or relay.
24. Faulty or corroded run/stop switch.
25. Tilt sensor needs a reset.
26. Security system not disarming alarm needs a reset.
27. Check for engine trouble codes.

Hi, Alan unless you are a professional competitive racer with specific engine performance criteria, let me set the record straight about fancy spark plug "HYPE" it's all "SNAKE OIL" Your bike when new came with a specific spark plug designed to give you maximum performance for the type of riding the bike was intended for, end of story. In my 60 years of riding everything on 2 wheels and 35 years of professionally wrenching on motorcycles, the factory OEM spark plug worked just fine. But what about the Multi Pronged-Platinum Core-Golden Tipped-Lazer Cut-Logo Etched-with exclusive patent designed LED cooling fins made in Hermetically sealed laboratories-packaged in Water Proof-Ballistic Transparent Thermoplastic Acrylic Plexiglass and endorsed by a secret subculture of NASA that sells for the outrageously low discounted price of only $25 a piece you ask? Excellent question, these plugs were designed for the Millennium Falcon. Seriously the bottom line in all these fancy plug designs claims may be true for those daring individuals trying to set land speed records but it would take a team of Nuclear Physicists using classified military grade Mass Spectrometers to prove it. Regular folks like you and me would never see or feel any difference. The temptation to spend 10x the cost of an OEM spark plug is great thanks to the highly paid Wall Street ad agencies, but trust me, save your money and replace your spark plugs with the ones recommended in your owners manual, if there was a better spark plug out there don't you think all the motorcycle manufacturers would use it? "ALWAYS" go by what your owners manual recommends!! The correct spark plug for a 1993 Kawasaki KX 500 is NGK BR8EG with a gap of 0.022" or 0.06mm installed with a dab of Anti-Seize on the threads and torqued to 20 ft-lb or 27 n-m. The spark plugs in your question are exactly the same you made an error, probably a loose connection between the brain and typing finger, despair not, it is a common affliction. If you like you may leave the other spark plug number in the comment box below, I will receive an "ALERT" icon and respond "toot sweet"
