For those of you who have ever had to remove the spark plug cap on your zenoah to install the steel braided shielding as supplied by MA or to shorten the high tension lead (as in my case) I have found a much more robust re-installation technique for the plug cap.
I personally dont like the small piercing from the plug wire as it only contacts a very small area of the high tension lead and is a definite weak spot.
First step is to remove the wire that fits on the spark plug from the rubber boot. Secondly, straighten the 90 degree bend leaving only a very slight bend.
First slide a one inch piece of heat shrink tubing onto the shortened high tension lead. Then take the straightened plug wire and press it into the high tension wire from the END. Keep pressing until the wire is close to the original hole, when youre close put a slight bend in the high tension wire which will cause the plug wire to poke out of the high tension wire.
Careful not to poke yourself in the finger (dont ask me how I know..)OK, so once the wire protrudes a few mms put another 90 degree bend in the wire facing the tip towards the high tension lead. Make sure that when you make this bend that you properly orient the coil wire to align with the spark plug. Being that the high tension lead is so short now, this will eliminate any unnecessary twisting of the high tension lead when fitting to the spark plug.
Then simply squeeze with a pair of pliers to pierce the wire back into the high tension lead. The wire will not be able to twist or pull out.
Slide a pice of heat shrink tubing over the hole and reinstall the orange plug boot using a bit of saliva or WD-40 for lube on the inside of the plug boot.
The advantages to this is there is a much greater contact area between the high tension lead and plug wire, also it cant twist or pull out.
Here is my relocated coil on my Predator.
