trying to find a dead misfire.

Postby roadwanderer2 » Sun Mar 08, 2015 10:19 am



ok boys and girls, im going out to my garage to see if I can't locate where the dead misfire at an idle is coming from on my bike. I THINK it could be coming from one of the spark plug wires from when I put on my new chrome spark plug covers. what I did was I had to move the left side plug wires so they would fit under the slot on the chrome cover, and I might have pulled the wires a little too hard and its possible I broke a connection inside the wires or somewhere up by the coils. I hope this will be an easy fix. i'll post my findings once I figure out what's wrong. i'll be on and off this site for a few hours, so please bare with me. I don't know how long this will take.

ok, I think I might have found the problem. somehow I must have inadvertently crossed #2 and # 4 plug wires. the only thing I can think of is when I removed the wires from the plugs, they must have reversed themselves and I didn't realize it and just put them back onto the plugs. I just finished switching them back, and the misfire seemed to have disappeared. once I have everything bolted back together, im going to take it out for a short ride to see if that fixed it.

well, I guess i'll find out soon enough. my wife just called, she's at her mom's house and forgot one of her afternoon med pills, so I have to bring it to her. this is the perfect chance to see if I was correct in what I did. this ride is about a 30 mile round trip so i'll know for sure if its working or not.

well, I took my bike out for a test ride and the misfire seems to have stopped. its still not running perfectly, but its much better. it still has a very slight misfire, so im going to pull the plugs, clean and regap them and put them back in, or maybe just go and purchase a new set of plugs.
