Hello, i am new to this forum , i am here to ask for help for my 09 Fatbob
So , i own a 2009 HD Dyna Fatbob fuel injected bike , everything was fine until one day it had trouble starting , it started but was misfiring with black smoke. Then a couple of days later , when i want to start it, it just cranks and misfires.
I read here on the forum that it might be the coil or the crank case sensor ( i got error p0373 )
I changed the the coils and the crankcase sensor, still the same problem . Now what ?
just wanted to mention , the bike is stored in my garage so no water problems , i checked the ground wires, and the wires coming from the crackcase sensor to my ECU.
i bought the battery this year and have it fully charged , i will try another battery tomorrow, i just checked the lines in the tank with flashlight and they seem OK .
Also , i have new plugs ( tried to start with the old ones as well )
below 10 under crank is considered bad.
do as mr. nevil suggested, charge and do two back to back load tests, first is to remove and surface charge and second to see what is going on.
if coil saturation is low, the output will be low so you will get a weak spark. if the cyl loads up with fuel, it will smoke black and hard to start.
