I have a 2000 VFR 800 with 73k kms and I have just lost the spark on the second cylinder. I purchased the bike in December 2015 and it has always misfired inconsistantly at low rpm, but when run up over 6000 it had great power on full throttle.
-I pulled the spark plug, it was all black, put in a new one, still same, no spark.
-I swapped coils and plug caps from no. 4 to 2 and still no spark on 2.
-Fitted a new lead from coil to cap, no spark.
-Continuity between 2 and 4 B/W coil leads is good.
Is there any way to test the R/Y coil lead to the Ignition Control Module?
Do ignition modules fail in this manner?
Are there any other tests I could do to help isolate the problem?
Thanks in advance for any and all advice from this great forum.
Regards,
Rosewood
