« on: September 20, 2019, 01:51:13 PM »
Is there anything wrong with using these for my 1981 CB650?

I used these ones from 4into1 for my cb650. They work great and stay flexible but those will work just fine.

 Those could be made to work... however, the stock coils have a screw - on type set-up, so the extra 'make your own' caps and crimp rings can't be used. If kind of looks like the spark plug boots are pretty short, too... just saying

I assume you would just cut them to length and stick the cut end into the coil? No special prep or trimming?

Would the boots being short be an issue?

Silicon wires is first choice, but... make sure you fit them well to avoid they will move too much in the riding wind. Any specs mentioned on 'suppression'? You don't want suppression in the wires. When suppression varies with length, I wouldn't pick them.

IF you have Dyna coils with automotive HT lead fittings.

My coils are original. Would the boots being short cause a problem? Is it better to use the resistor NGK caps with regular plugs or resistor plugs and these caps?

How are you planning to attach the new wires to your original coils?

As far as I know, you just stick the wire in the coil and tighten down on the threaded caps.
