This appears to be the best option. When all else fails brute force works! Thanks all!


What's your mileage? Who cares. Is it practical? See #1. What happens when it rains? You get wet.

Or if you're locked into the spark plugs with the threaded on ends, keep them, but swap out your spark plug boots that use the spark plugs with the ends removed. Most of the Japanese bikes of days gone by used them.

I used to have this problem. Threadlock resolved it for me.

You can see why the plug caps come loose with the amount of wobble on the HT leads.
Messing around with the GoPro I've got the shot.

And you can always change the leads and their ends to a brNd that might clamp onto the plug more firmly.

I had them unscrew on mine once and had a strange misfire I even hooked it up to my laptop see if the codes would give me any indication and it said that one bank was out of range or something like that what I ended up doing is pulling off those threaded on bits crushing them a bit with a pair of pliers and then screwing them on very tightly and that seems to have done trick
