 I did try the plug end but that was fine,
 I used a silicone sealer (flexible bathroom type) as that's what I had to hand

         +1. When I had the tank off my bike a while ago, I noticed the HT lead seemed, well, loose in the coil. So I did exactly as above and used marine silastic to (hopefully) seal that area. This is an old 'mod' shown to me years ago by a very experienced competitor in reliability trials, which my mate and I have applied religiously to almost every dirt bike we've owned.
         
        
 Silicone has the added advantage of bracing that area where a tightish bend in the HT lead exists, such as on XT660s. There's little doubt that it's a potential issue for all of us.
