Replacing HT plug wires

[alke46]

from the coil to the plugs, is it necessary to insulate the leads from the engine heat? The originals had some kind of outer wrap to protect from heat I guess. Is this needed and if so what do I use?
I have some heat shrink material that fits right over the 7mm wire but it does not appear to be as thick as the original stuff.

I'm thinking the heat shrink stuff would be sufficient but is it even needed?

TIA

Most wires available today should withstand the heat of the engine, just don't let them touch the exhaust pipe.

When redoing the wires on my bike I recycled the outer covering and put it on the new HT wires. Squirt a little WD-40 inside and it slides easily.

Creative thinking Ed. I am instead going with new Accel brand coils. I am tired of fighting this losing battle to save my originals.

On my last attempt, after replacing the HT leads and installing back on the bike, I checked for spark and only got spark on the 1st revolution of the engine. After that, I was back to no spark again.
The GS hasn't been out of the garage for way too long already so now we will see how she responds to new coils.
