Question about 2004 Harley Davidson XL 1200 C Sportster Custom
The bike has about 6200 miles.How do I check to be sure that the new pipes haven't burned the valves or are over rich? What are the chances of either? could I cure over rich with K&N? What about lean, how to detect over lean?
Too rich or too lean condition will only occur on that model if the o2 sensor,or computer is bad.(If it runs,You can rule out the computer)
It has EFI system and the computer controls the mixture constantly adjusting it.
