It's okay I've ripped it the other way by using the same NGK plug for almost 15,000 miles in my B5.
I intend to check it later today when I do an oil change. I may refit it I may not. It's been totally problem free, never been cleaned and only been out of the bike once at 5,500 miles for this photo opportunity. I may fit a long lasting Iridium plug just to see how long it will last,but I don't think I'd actually benefit from one.
The fatter the spark the less chance a plug has of fouling in less than optimum running/starting conditions. Some bikes will benefit, some bikes won't, older style electrics and engine designs more so than newer ones.
Removing an unnecessary resistor that might fail at some point and fitting a quality plug cap is a very cheap upgrade to a better ignition circuit. I've been stuck at the side of the road on a soaking wet night with a metal encased plug cap more times than I wish to remember before realising that having a metal encased plug cap is not always a good thing. I've been throwing them away for some time now.
EDIT:- put a file to the centre electrode, gapped it and decided to put it back in the bike. I'll change it when it's done 20,000.
