Cheap Spark Plug Wire Splice ?

kzdcw wrote: I know it's probably just a batch job, but my #4 spark plug wire on my 77' KZ1000A is a little short in length. Even routing it the shortest way to the new angled spark plug cap I have, the wire just allows the cap to screw into it. Not banjo string tight but hardly any play with the wire.

A cheap and easy way to repair this I think, would be using a short sharpened finishing nail and driving one side into the stock wire leaving the coil about an inch from the coil. Then attach a new section of solid core copper wire to other side of the finishing nail in the additional length that I need. Then use some shrink wrap to insulate the joining wire ends.

Good idea or Bad idea ?

Or is using the NGK spark plug wire splice better ?
