Question about 1987 kawasaki VN 750 Vulcan

1 Answer

I tried to start my '85 kawasaki 454ltd for the 1st time this

I tried to start my 454 for the 1st time this year, the bike started up, but soon died, and then on the 2nd try, a very loud backfire from the right side exhaust pipe, some black smoke came out, then nothing, the motor turns over but no spark, I checked both spark wires, with the plug still in, but grounded to the side of the motor, no spark from either side, I replaced the main fuse (the only one I could find under the seat ) still no spark, I'm not sure where to look next...any help..?? thanks

    I put in new plugs, used some starting fluid, and it fired up, so now i'm in the process of cleaning the carbs, petcock and lines, putting in some new gas, and it should be good to go...
    thank you for your quick response, it was extremely helpful.

Sounds like a bad CDI box. That is part of the ignition. Do you use a fuel stabilizer when moth balling your bike each year? That may have been part of the backfire and shut off. Your bike having carbs may have gummed a little. Are you handy? Try spraying a small shot of starting fluid in the air cleaner,small shot! Just to make sure it's not a fuel problem. Try a different plug in the wire also. Sounds weird,because I'm pointing out fuel starve problem but the plugs could be fuel fouled. Anbd a new set of plugs for that bike shouldn't be that expensive and a good place to start.

1986 kawasaki 454 ltd manual


Hi, Maddy the vast majority of service, parts fiche, and owners manuals on the internet are "FREE" to download and all service manuals contain wiring diagrams in the back pages. The rest usually charge a modest fee around $10 and there is a handful of obscure, rare, obsolete, and very old models that are no longer or never were available, for these rare occasions I shall look on eBay and find the cheapest one available. Most of the manuals will cover your exact make, model, and year otherwise one will be provided that comes as close as possible to your bike and will have most of the same info that an exact manual would have. If there is no $ sign after the manual link it is free to download for viewing or printing. To download your manual please click on the blue links below. Good luck and have a wonderful day

Why does my kawasaki kx 85 run ok for 5 minutes then just die then start up when it cools again then die again have put new coil on but still same


possible blockage of fuel cap if after running you remove the fuel cap and there is a hiss of air rushing in then the cap breather is defective try running the bike with the cap off and see if it runs ok. if that is not it then possible dirt being lifted in the fuel tank. clean out the fuel tank ensure no dirt is getting into the fuel system if that is not the case then check the carborator, i dont think it is a heat problem to test remove line from tank to another fuel source tank and run the bike and see if you have the same issue. i hope this helped. do this in a well ventilated area due to fuel fumes and exhaust gas.

1986 Kawasaki 454 ltd cranks but won't start


Hi, Twireone9 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. 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.
17. 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.
18. Loose or corroded wire connection at the coil or plug between ignition sensor and ECM module.
19. 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.
20. Ignition timing incorrect due to a faulty ignition coil, ignition module or MAP, CMP, CKP, O2, TPS, ETP, IAC sensors.
21. Faulty neutral, clutch, kickstand safety switch.
22. Faulty fuel pump or fuse or relay.
23. Faulty or corroded run/stop switch.
24. Tilt sensor needs a reset.
25. Security system not disarming alarm needs a reset.
26. Check for engine trouble codes.

Starting and once started won't run


The problem seem to involve a number of circuits, I would suspect the Key switch as it supplies power to all affected systems. The dieing on release of the clutch is usually the kickstand safety switch. If the kick stand is not up, and the bike in gear, then when the clutch switch detects release is kills the engine so you don't kill your self.
Check or replace these switches.

Hope this is of some help.

Bike dies if rpm rise above 4 or 5


Hi!

That clicking noise comes from the start-relay, that tells your battery is out of power or almost out of power, when the battery isent giving enough of power the start-relay clicks. Recharge the battery,
Now for that other thing, that your bike dies around 4-5 rpm, that can be caused by many things but i think that you will find the solution in the carbs. You told us that the bike has been standing outside for 3 years, that tells me that you carbs is in need of cleaning. Inside the carbs is a lot of smal parts that opens and closes when you hit the gas, after so long time outside some part dosent work as they should, therefore when you hit the 4-5rpm the bike dosent get the right mix of fuel and air since the carbs harsh and the bike dies.
Take the bike to a repaire shop and let them clean and calibrate the carbs and your problem will be solved.

Good luck
