No... it’s to get someone else to do that and see if they Yelp !!
Long story - there is a point...
I've been working off and on with a guy with little mechanical aptitude and even less electrical aptitude. It's a 79 Bonneville he bought new. I fix it, test it, have him test it, and then in 1-2 weeks he's messed with it and it won't run properly. The last time I rebuilt the MKII carbs, put in the correct spark plugs, and admonished him severely for letting the bike idle on the side stand with the enricher on, for 10 minutes! He took the bike home, rode it a couple of times and then called me saying the left cylinder wasn't running. Of course he assumed I screwed up the carbs. I tried to get him to check the spark but he assured me that since he had Tri-Spark and a dual output coil that it was not possible to have spark on one cylinder and not the other. I finally got him to pull the plugs, reconnect them to the plug wires on and put the plugs on the head and then kick. Now he told me he couldn't see spark in either plug. By now I was quite frustrated and gave him three options:
1) Call someone else to work on his bike (good luck on that).
2) Get his wife to look at the plugs with something to shield the sun while he kicked.
3) And, here's the point of this story: I told him: "Man up, grab the plug with your hand on the business end and the same hand touching the head, and kick". He said, won't that shock me"? I said, if there's spark it will but it won kill you.
At that point, he started listening, and magically could see the spark on the right side and none on the left. Had him swap the plugs - problem didn't move. The wire were molded into the coil so couldn't swap them. Had him unscrew and swap the NGK caps - problem didn't move. Told him to replace the coil and call me. Bike is running great again - I wonder how long this time.
