"Brisk" spark plugs

[Worty]

The only time I had a 'problem' with NGK was entirely my fault.  I found the screw cap could work its way loose over time and, concerned this could cause a problem, put threadlocker on it not realising that said threadlocker acted as a partial insulator

Once I discovered my error, I now screw the caps over a few strands of copper wire which 'locks' them in place.

The bike almost always starts within one or two kicks from cold, maybe three if it's hot.

Screw caps coming loose shouldn't really be a problem (do 'em up with pliers) but if they do come loose then just crimp the plug stud thread slightly with the wire cutting part of said pliers and screw the nut back on.

Just a question before I try Brisk plugs.  Are the ceramic bodies glazed?  All other brands of plug I've seen lately seem not to be glazed, so soak up unburned fuel and collect contaminants.

I seem to recall that they are glazed (unlike many others) which is why they can be cleaned.

If modern NGK plugs are not glazed, why does that not appear to matter on my 650 of another marque in the BSA/Triumph group?

I have managed to foul and clean the plugs many times.
