Question about 2002 Suzuki VL 1500 Intruder LC
The intruder idles fine, and revs fine without issue when cool. But it quickly begins to misfire if I hold a mild throttle as it warms up. The hotter it is, the worse the misfire. I checked the main jets - clean. The forward plug was black as is the tailpipe. It has about 30Kmiles on it.
The voltage to both coils is right at 12 volts or a little more. I'm leaning toward a bad coil to the forward cylinder. How can I check it and what would be the test specs? Any help would be appreciated. If it could be something else, don't hesitate to recommend a test.
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.

If the exhaust is blowing black smoke when misfiring, it means that the mixture is rich, so you should look for a blocked air cleaner, or stuck choke. If the smoke is blue, then it means it is burning oil, which is more serious.
Try running the bike in the shed, with the air cleaners off and see if the problem changes
