SOURCE: Any way to adjust the rear shocks on a 1996 vulcan 1500-a10 ?

dear susan shock adjustment for the rear shock are done with c wrench. you will notice at the top of the shocks there is a ring with 3 adjustment cams. the wrench is placed in the two holes you see on the shock opposite each other this is where the wrench fits you simply turn either direction for softer or harder ride. this adjustment puts more or less tension on the spring. i own a 96 vulcan as well hope this will help you jim

1200 sportster not running on back cylinder


Verify the cylinder is not firing by measuring the temperature on the exhaust right out of the cylinder. If it is not firing the tempature will be much cooler than the front cylinder. Once you have determined the rear cylinder is not firing then you need to perform a compression test on the rear cylinder. If it is not with in specifications, you may have broken rings, burned valves or hole in piston. Until you run compression test you will not know which way to go.

I have a 2006 pacifica misfiring in cylinder 4. How do i locate that one


Go to the auto parts store and get a tester that fits on the spark plug and on the spark plug coil and it will flash if the plug is firing.You could use a inferred thermometer and aim at the exhaust header and the cold spot is the cylinder not firing. Number 4 is the cylinder in the middle by the radiator side

How do I do a compression test


You need to get a compression tester that will fit to your vehicle.
Remove the spark plugs and fit the tester to the plug holes.
You wiil need to people for thenext step.
One person must look at the guague while the other one crank the vehicle and keeping is foot down an the accelarator.
You compare the reading's of the cylinder's and make sure depending on model and age of vehile that there is not more than a 10% differance between the cylinder's.

Which fires first front or rear cylender on a 1982 FXR 1340


Neither. The front cylinder fires on one rotation of the crank and the rear cylinder fires on the second rotation or vice versa. Since both cylinders fire on different revolutions instead of the same rotation, neither fires first. But, the ignition system, provided it's stock, fires both spark plugs at the same time. It's called a dual spark system because it fires both plugs at the same time. Since one cylinder is on the exhaust stroke and is of no concequence, it's called a 'wasted spark". You can switch the spark plug wires on a stock Harley Big Twin, not the V-Rod, and it will run.

Good luck

#1 plug is miss-firing.I have replaced plug and wire,but keeps miss-firing only on#1 plug.have been told that coolant is possibly getting in #1cylinder.also I have been told #1 coil could be bad.witch is...


Could only be a few things. The coil #1, Fuel injector #1, Stuck intake or exhaust valve, or blown head gasket allowing coolant into cylinder #1. Use a spark tester to check the spark coming out of cylindr #1 if checks good then ohm test the injector when it is warm. Check other injectors to compare. Do a compression test on cylinder #1 and test other cylinders to compare. If cylinder is low compression suspect valves and or head gasket. If compression is low then het a leak down tester to test if a valve is broke or sticking. On your sable i would suspect injector or coil most likely.

Check the coil packs and EGR:
Exhaust Gas Recirculation System Operation Application of the Exhaust Gas Recirculation (EGR) gases is regulated by the Powertrain Control Module (PCM). It is based on engine coolant temperature, engine speed, vehicle speed, throttle angle and Manifold Absolute Pressure (MAP). The operation of the EGR system is monitored by the PCM, which allows gases to flow at a calculated rate and compares it against MAP sensor and oxygen sensor activity. The PCM anticipates an increase in MAP voltage and an increase in O2 sensor voltage.
Electrically operated vacuum control solenoids used to control the flow of vacuum to the EGR valve, rely on pulse-width duty cycle commands from the PCM to control its operation. Using input values and the operating conditions previously mentioned the PCM completes the electrical circuit for the solenoid to allow vacuum operation of the EGR.
In addition to solenoids controlling vacuum flow, the incorporation of a back pressure transducer regulates vacuum signals independently of electrical signals. When back pressure in the exhaust system is low, the transducer pintle is open and manifold vacuum is allowed to bleed off. As back pressure increases the amount of vacuum allowed to bleed off is reduced resulting in more vacuum being applied to the valve. This allows air pressure to open the valve.
The following symptoms can be caused by a faulty EGR valve due to loose connection, bad grounds, high resistance in the circuit, or opens in the circuit.

Diagnosis and Testing Secondary Spark Test These spark tester looks just like a spark plug, attach the clip to ground and crank the engine to check for spark 91052p10.jpg
This spark tester has an adjustable air-gap for measuring spark strength and testing different voltage ignition systems 91052p11.jpg
Attach the clip to ground and crank the engine to check for spark 91052p12.jpg
This spark tester is the easiest to use just place it on a plug wire and the spark voltage is detected and the bulb on the top will flash with each pulse 91052p10.jpg
The best way to perform this procedure is to use a spark tester (available at most automotive parts stores). Three types of spark testers are commonly available. The Neon Bulb type is connected to the spark plug wire and flashes with each ignition pulse. The Air Gap type must be adjusted to the individual spark plug gap specified for the engine. The last type of spark plug tester looks like a spark plug with a grounding clip on the side, but there is no side electrode for the spark to jump to. The last two types of testers allows the user to not only detect the presence of spark, but also the intensity (orange/yellow is weak, blue is strong).
  1. Disconnect a spark plug wire at the spark plug end.
  2. Connect the plug wire to the spark tester and ground the tester to an appropriate location on the engine.
  3. Crank the engine and check for spark at the tester.
  4. If spark exists at the tester, the ignition system is functioning properly.
  5. If spark does not exist at the spark plug wire, perform diagnosis of the ignition system using individual component diagnosis procedures.

I have a 1998 4.6 triton engine missing on #8 cylinder


Make sure your testing cylinder 8. Ford numbers their cylinders differently that others. #8 is the rear cylinder on the driver's side of the engine. The ignition coil may be putting out a weak spark. It should produce a spark capable of jumping a half inch gap from the coil terminal to the end of the plug wire. Next step without diagnostic tools is to swap fuel injectors with a good cylinder. After that check compression and compare with a good cylinder (hold gas pedal to fully depressed position before turning key to "on" to place computer in "clear flood" mode so engine won't run when checking compression).

Four things I can think of:
1) There is a short in your spark plug wire. When you bend it to connect the plug in the machine it allows the exposed cable to contact the engine block. Examine the wire all the way to the coil.

2) Flywheel key is sheared ( you obviously know how to take off the flywheel since you checked the seals).

3) Flywheel air gap is not set correctly. Loosen the coil. Put the cover of a notebook or the cardboard piece of a cigarette pack between the magnetic portion of the flywheel and the coil. Tighten the coil down. This will get you the proper gap.

4) Your cylinder/piston or rings are scrubbed out. Even though it passed a compression test, on rare occasions it will loose compression only when it fires. So do the following:

Remove your exhaust manifold. Look into the cylinder with a flash light. You are looking for scratches. Anything larger then a light fingernail is definite proof you need a new cylinder/piston assy.

If it passes that test do the following:

Pour mixed fuel straight into your cylinder until 1/4 full. Slowly pull your saw over while looking into the cylinder. If you see bubbles after the ring/rings go by then you need a new cylinder/piston assy. On rare occasions if no scratches are present on the cylinder wall or piston, you may be able to change just the rings.

First if you can get a inline spark tester so you can see if your getting spark with the plug installed.
