KZ650. Never failed me. Till Now. Need Ideas: Coil, Carb most likely

You really shoud not pull plug wires with the engine running. Secondary voltage can get high enough to break down insulation in plug wires and coils. Secondary voltage is limited by the spark plug gap. The larger the gap, the higher the voltage must build before it can jump the gap.
When I want to remove spark from a cylinder, I put a spare plug in the plug cap and ground the base.
 

Thanks for this. I will keep it in mind. Hopefully the coil is still OK. For now I will change the wires.

Ive been researching since Ive posted. It seems that wires are NOT supposed to shock you when you pull them off the spark plug, and if they do, they are probably cracked and leaking. Im going to replace them.

Snap On make these for that very purpose 

 

I repeat, spark plug wires are not supposed to shock in the way they shocked me the other day. Im changing them. They have been resting on the cylinder head and are probably fried

Pulling leads with plastic pliers was the normal method of mis-fire diagnosis "back in the day" hence why Snap-On made a tool specifically for this. Even if you pulled a brand new lead on a running engine it is going to "bite you" (I have over 40 years experience !)

In the past, Ive pulled wires  from the spark plug while a bike was running, and did NOT get a shock. As I mentioned, all my research says the wires are arching. I will be changing them and will post an update. I'll have to find wires that are compatible with the Dynatek DC1-1 coil that is on the bike. I will also take the coil off and test it.

I'll provide everyone an update when i change the wires. btw, i know whats going on. I mean in re the forum. Thats all I'll say. Its fine.

I am confused, what do you mean by this ??

and:

Perfectly fine leads and caps can shock you if the bike is running and you pull the cap off. Because the bike is running the coil is pumping volts to the cap and if the least resistance to earth is through you then that's the route it'll take. 
If the cap is on a plug and the plug is in the head then it's earthed and will take that route. 
Coil power has to go somewhere and if the cap isi not earthed and you are it'll go through you. 
Basic physics. If what your reading says differently it's wrong. 

All I can say it that the advice and guidance offered on the forum comes from decades of experience in most cases, however who you choose to listen to is entirely your choice. I checked out your link and the "expert" authors ?????
PS: If you touch the leads and get shocked when they are connected to the plugs as normal then they are faulty 

 

Ive done it before, without being shocked. Im changing the wires and will keep you all updated.

I wouldn't bother trying to tell him anything. He seems to ask a lot of basic questions and then argue with the more experienced people about the answers.

I think he is actually someone who was banned from the site a year or two (?) ago for bad behavior. If it's not the same guy, he's doing a pretty good impression.

Anyway, now that he is apparently keen to do his own research, perhaps he can go do that and leave us lesser mortals alone.

​​​​​​. Obviously not reading any of Einsteins stuff cause he knew nowt about physics did he.? ​​​​
