Spark Plug Wires

imported post

If it runs well and you don't see any sparking at night, I don't see the need to change them out. Just my opinion though.

the wires are not carbon core . they are copper core . as long as the outter insullation is good they will be ok. no burned spots or cracks .

Thansk guys. I'll have to tinker elsewhere then!

Really? Were they the original braided copper wires?

I removed the old ones, and i'm pretty sure they were original, they even had little stickers saying which cylinder they were for. at the coil where they screw in, they were litterally compressed to about half the original size, and they were very hard, not supple at all. for the new i just bought 8 feet of 7 mm copper core wire from bob's, cut it to length, screwed on the caps, and screwed into the coil.. felt the difference first ride!

They were original if they had the markings. I'm surprised it made a difference.I didn't knowcopper strand could deteriorate or corrode. Maybe it was just the connections.

In any case, I might try changing mine.

change the sparkplug covers, around $4.00 each. little known fact, there is a resistor and spring inside the covers
that can be tested for omns.
