Misfire forward cylinder

Front plug wet, rear plug black. Resistance of plug conectors 9k ohms on front 7k ohms on rear. I have found most bikes run around 5k ohms. What is the correct reading. At higher rpms front cylinder will attempt to fire. Both plugs will fire removed from cylinders and grounded

First you'll need to get a jet kit from West coast star. Then you'll need to jet the carbs to run equally. This may take some trial and error. Another thing that worked on my bike was the upgraded coil kit they sell. It's almost double the voltage of the stock coils and comes with better insulated wires for a more uniform resistance. I haven't had this problem since. It'll make the cylinders fire evenly and save you from those pestiferous fouled plugs. I hope this helps.

2002 harley electra glide front spark plug turns black


A blackened spark plug is a sign of a rich air/fuel ratio or a misfiring plug. You stated that you changed the coil and wires, but did you change the plugs? Spark plugs, even new ones, can, and do, go bad (excessive internal resistance). Make sure that the plugs are also the correct part number for your application, as they could be of the wrong heat range for your bike. I have even heard of guys using a colder plug in the rear cylinder and a hotter plug in the front cylinder because the front cylinder tends to run a little cooler than the rear (increased air flow in the front).

Bike breaks up at 2500-3500 rpms


Is it good above this rpm range or not.

Check for trouble codes.
2001 TOURING Diagnostic Trouble Codes (DTC) and Fault Conditions
DTC NO. FAULT CONDITION
12 MAP sensor
16 Battery voltage
24 Front ignition coil
25 Rear ignition coil
35 Tachometer
41 Crank sensor
44 Bank angle sensor (within TSM/TSSM)
detects possible theft attempt
52 RAM failure
53 ROM failure
54 EPROM failure
55 Ignition module failure

Battery condition and connections may cause misfires. Inspect for corrosion at battery terminals, main circuit breakers, ignition fuse terminals (GY and R/BK), right handlebar connector [22] and coil connector.

Fuel system problems may cause misfires.

Spark Plugs OFTEN cause misfires, even plugs that look good. If carbon tracking is evident, replace them.

Spark Plug Wires may cause misfires - Front/rear 20 in. 5,000-11,666 ohms. Wires must be clean and tight. Excessive wire resistance or faulty connections can cause coil damage. If carbon tracking is evident, replace the ignition coil and inspect the spark plug wires. Spark plug wire connectors can corrode and should always be coated with dielectric grease to prevent this. If there is any corrosion replace the corroded parts.

Coils may break down and cause misfires but not usually at a given rpm range only. Coil testing can be performed by substituting a known good coil for one causing the no spark condition. The coil
does not require full installation to be functional. Verify a possibly
faulty coil by performing a resistance test. Test the primary coil resistance on your coil. Disconnect all the wires going to the small terminals (primary) on your coil. Using a good ohmmeter on Rx1 setting, test the resistance between the two small terminals. You should read somewhere between 2 and 3 ohms. If you read more, the coil is bad. Before you do this test short out both leads of the ohmmeter and if the reading is not zero you will need to write down or otherwise remember the number and subtract it from the reading you get from the primary circuit test or you will have an incorrect resistance reading for the primary wires because you will also be reading the ohmmeter internal resistance and/or the wire and lead resistance added to the primary wiring resistance.

You can also test the coil by leaving the "hot" wire on the coil and replacing the other side (ground side) with a short piece of wire. Turn the ignition on and temporarily ground the short piece of wire you put on the "out" (ground) side. When you take the wire away from the ground, (which will collapse the primary current into the secondary) you should see a spark at the plugs if it is a wasted spark system or at one of the plugs if it is not a wasted spark system. If you have current to both sides of the primary of a two part coil both plugs should get a spark whether wasted spark system or not as you are energizing both sides of the primary and collapsing both into both secondaries at the same time when you remove the ground wire from the cylinder head ground.

Take the plugs out of the cylinder heads and lay them back on it so that they have a good ground. Then watch the spark plugs closely when you turn the ignition switch off. You should see a single spark on each plug. This tell you that the coil is getting fire and that it is good and your problem lies elsewhere. You get a spark on both plugs because it is a wasted spark system that fires both plugs simultaneously, one on power stroke and the other on exhaust stroke. This will not work on 2006 and later EFI as there will be no spark with both plugs removed.

Manifold leak Spray water around induction module seals with
engine idling. If RPM changes, change seals.

Improper fuel system pressure may contribute to one of the following conditions: 1.Cranks, but won't run. 2. Cuts out (may feel like ignition problem). 3. Hesitation, loss of power or poor fuel economy. Fuel pressure must be a steady running pressure of 55 to 62 psi (380 to 425 kPa).

Plugged, dirty air cleaner may cause rich misfire.
Plugged/dirty fuel filter may cause lean misfire.

Missing on front left cyl. popping when you give it gas left front plug is clean and wet check fire and it is strong and blue compression is good


G,day. If only the L/H front cylinder is the problem & compression is good then the most likely possable causes of your problem are - A open circuit spark plug cap on that cylinder or a carburettor fault(blocked jet) on that cylinder(or carby balance setting).I would suggest testing the ignition coil secondary resistance.Do this by removing plug caps from cylinders 1 & 4. Set multimeter to kilo ohms(ohms x 1000) .One test lead to one plug cap- other test lead to other plug cap(do not allow probes to touch your fingers-touching both test probes whilst undertaking this test will give a false reading).reading should be 10 to 20kilo ohms.If open circuit-remove plug caps from leads( they unscrew)and test caps seperate. Should read 5 kilo ohms. Replace if open circuited(This is a common problem on all road bikes).If that sounds to difficult, any good motorcycle shop should be able to check them while you wait.It only takes a few seconds.Sorting the carbies without experience is very tricky.Have the carby balance & mixtures checked first in case its just an incorrect setting before pulling off & cleaning the carbies.
Hope this is helpfull

Honda 1986 vf400f nc13 engine front two cylingers not firing help


If the spark appears to be weak only for the two front cylinders, then I would suggest checking the electrical connections for the ignition coils.
If the spark for the other two cylinders looks the same (yellow), then I'd suggest checking the compression on the non-functioning cylinders. A compression reading of 140~160PSI is what you're looking for. Low compression indicates internal engine damage - or could be from something relatively simple - like insufficient valve tappet clearance.

If the bike has been sitting for a long period of time, it could be that the carburetors are plugged up with fuel varnish. This can cause some cylinders to not run. A complete carb disassembly and clean-out will be needed.

2000 Suzuki Intruder VL1500 misfire


Hey, I have a 2000 Intruder 1500 as well and in the last week I have had the exact same problem and was thinking the same thing. I checked the front plug and it is pretty covered in black and changed both plugs. This did not help, still seemed like the front cylinder wasn't working just right. If you could let me know what you eventually find I would really appreciate it.
