The spark plug wires on my '93 were getting kind of brittle so decided to do a replacement. Checked around & stock or aftermarket items were way out of my price range so with the advice from DaveO430 a DIY project was formulated. I went to NAPA & got 12 feet of solid core bulk wire & headed fro Dave's place.
Pretty simple process really;
1) remove a plug wire
2) use a flat blade screwdriver & remove the screw in fitting & resistor fro the boot -

3) check the resistor for proper resistance -

4) work the boot up the wire to expose the metal end piece & then use a soldering iron to remove it from the wire -

5) Use a soldering iron to remove the metal end from the wire -

6) cut new piece of wire & slide boot on
7) solder metal end onto new wire -

8) put the resistor & screw in piece back into the boot
9) install back on to bike, repeat 5 more times

As a help only do one wire at a time. Total cost was about $15 & a couple hours if time. Hope this helps some folks, Andy.

Thanks Andy and Dave
This will help many as the wires start deteriorating on the 1500s.

Does it use the same 7mm copper core wire the 4 bangers did? I would assume it did........
Yes, same wire.

Did you notice any performance difference?
He hasn't ridden it yet, will be a while.
We did find a resistor bad and found the ones for an 1100 are the same. I had plenty of those lying around.

Looking at the pictures of coils for the GL1500, they remove and install at the coils the same way since the GL1100 coils.

Wire just sticks into the coil, penetrating a nail in the coil. Wire is held into the coil with a compression ferule and nut.

Remove by loosening the nut all the way and pull the wire out.

I put the NGK Iridium DPR7EIX-9 and put 4300 miles on a ride out west, they seem OK on highway but lag on low end. Had to use partial choke halfway when starting up cold and had to tweak choke for the first 3-5 minutes until it would run without choke. Also seemed to be rich after choke was off enough to burn our eyes when behind bike while ideling.

Did a compression check on my 97 Goldwing GL1500 today and found all cyclinders within Honda specs they were between 195-205psi.

Swapped out NGK Iridium DPR7EIX-9 with a set of E3 Dimond Back's E3.36 and immediately saw a great improvement at low end - Hell the bike starts cold without any choke at all now, but have to give a little after a minute or so or it will practially die. THe Iridium's would have never started without choke. So smooth through powerband now!

E3 all the way!:)
