Spark plug wire

Ok I was talking to a guy who increased his spark plug wires from 7mm to 8mm. Is it possible to just replace the wires and not ends assembly that goes on the ends that connect to the spark plug? If so, how do I get the ends off the wires?

the ends twist off the wires, but 8mm wires need 8mm spark plug ends, or you have to shave insulation off the wires to get the 7mm boots to fit the 8mm wire.

I have a spool of 8mm Accel wire as well as the cheap replacement wire from Dennis Kirk. It was no trouble at all to get the 8mm wire into the NGK plug ends, but I couldn't get it into the stock coil side retainers at all. I used the DK wire temporarily, but would like to use the 8mm wire since I've got it and it appears to be much higher quality than the generic DK wire. Can anybody that's used 8mm wire comment on how they got around that?

Could trim rubber insulation a little off the end of wire?

I tried that, but removing the rubber insulation makes it far too thin. I didn't see an easy way to remove just a little bit of insulation. Basically an all or nothing thing. I'd love to be wrong about that, though.

I switched to 8mm years ago. All I did was use my table top grinding wheel to evenly shave off the excess sheathing till it fit the stock coil.
Also, no problem with the NGK caps.
Since sold them to Wib when I stripped the bike.

So you just held it up to a bench grinder? That could work. Definitely an option I hadn't considered.

Yeah, the knife was my first try and an utter failure. Thankfully I have 75 feet to work with so burning an inch or so as scrap wasn't a tremendous loss.
