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).

If it's running rich already, a bigger jet will just make it run even richer.

As far as the rear cylinder running hotter, that's just the nature of the beast with a V-Twin engine, because the front cylinder blocks the airflow to the rear.

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

Trouble codes PO300, PO302, PO304,PO306,PO308


If you get
P0300
P0301
P0302
P0303
P0304
P0305
P0306
P0307
P0308

error codes and
you have an engine that misfires or runs rough, it can be the injector for that
cylinder or the coil pack. The P0300 code is a random misfire code and may or
may not be the above. All the other messages are for misfire of a particular
cylinder indicated by the last digit.

Test the coil pack by switching it to another spark plug and
see if the problem follows to that cylinder.

If that makes no difference, it is very likely the injector.
Disconnect the injector connector of the same cylinder and measure the
resistance. It should be 13.5 to 14.2 ohms at 70 degrees temp. It can be up to
16 ohms if the engine is hot. If you see a really high resistance or an open or
short then you can try to change the injector. If not, you can remove the fuel
rail on that side and switch the injector to another cylinder and see if the
problem follows to that cylinder.

You
need a 22mm wrench to remove the fuel pressure regulator. The other connections
are std. When all screws are removed, GENTLY wiggle the rail up and guide it
smoothly out. Don't put any sideward stress on the injector bodies.

Here is how to identify cylinders

All of the
injector connectors have a Black with red stripe wire. The corresponding other
wire color on the injector connector that matches with above are

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.
