1999 Kawasaki VN 1500 Vulcan Classic compression very high


Take a look at the exhaust valves. If the exhaust valves are not opening, the pressure will build (sort of like an air compressor). There should be a cam for the intake and the exhaust, make sure the cam and the valves are operating correctly. Also, check your base gasket and head gaskets. If either gasket is too small, it'll boost your cylinder pressure. It is common to switch out the base gasket and/or head gaskets with thinner ones as an inexpensive mod to boost cylinder pressure. Lastly, too much carbon on the piston head or cylinder head can boost cylinder pressures (rare); the carbon can be a problem which can lead to detonation as well.

Hi, Brandon my guess is you have a faulty spark plug or spark plug wire/cable or ignition coil or wiring to the coil is corrupt, check the ohm reading on your plug wires/cables for more information about your question and valuable "FREE" downloads that you will need please click on the links below.

1997 Kawasaki VN 1500 Vulcan Classic the engine is only firing on 1 cylinder


Hi, Anonymous you need "FIVE" things in order for a cylinder to run properly:
1. FUEL: in order to validate your not getting fuel spray some starting fluid into the air cleaner and hit the starter button, if it fires up and runs for a few seconds then you know you have a fuel delivery issue. Multi carb banks should be bench "SYNC"
2. SPARK: remove the spark plug and with it connected to the spark plug cable ground the threads to something metal you should see a bluish white spark if not you have a faulty spark plug, spark plug cable, ignition coil, condenser, CKP, ECM, sensor or the wiring in between.
3. COMPRESSION: you must have at least 80-100 PSI for most bikes, multi-cylinder engines should be within 10-15% of each other if not perform a leak down test you may have a burnt or bent valve or hole in the piston or broken rings.
4. CAM TIMING: confirm your timing marks are aligned to see if the cam chain or adjuster are worn out and the chain has skipped a couple teeth.
5. IGNITION TIMING: on older bikes check to see if your points have not closed up, timing plate has not become loose and confirm with a timing light for proper retard and advance functions, on newer bikes where timing is controlled by an ECM and is nonadjustable check you CKP, TPS, MAP, O2, sensor or its counterpart for integrity.

1999 Kawasaki VN 1500 Vulcan Classic Tourer no spark


Hi, Tim and the usual suspects are:
1. Fouled spark plugs.
2. 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 preliminary 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.
3. 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.
4. Loose connection at ignition coil or plug between ignition sensor and module.
5. Spark plug cables in bad condition, shorting/leaking, spark plug cable connections loose check for spark leakage in the dark.
6. Faulty ignition coil or electronic control module.
7. Faulty pulse coil.
8. Faulty CKP, CMP, or BAS sensor.
9. Faulty ignition switch.
10. Faulty run/off switch
11. Tilt sensor needs a reset.
12. Security alarm failing to disarm needs reset

2003 1500 Vulcan classic fowling Rear Plugs


Perform a leakdown or compression test on the bike before you go to the expense of a top end rebuild. You may find it is something as simple as the rear cylinder not firing properly or perhaps fuel mixture to that cylinder is not correct.

Post a picture of the plugs that are fouling. Are the ignition wires crossed back there? Both plugs may not fire at the same instant, some dual plug setups fire slightly apart (although I can't think of a way that would cause severe fouling like you describe.)
