E: Engine Does anyone index their spark plugs ?

Well spotted sir, I'm too tight to buy them anyway !

I like to call it sustainable financial decision making!

Looks correct. Tops don't screw off.

Nope, and I don't check plug gaps either. Here's the bike doing the fastest lap at Goodwood on £1.47 NGK plugs.

When first started the Manx, it only ran two seconds before the piston had made plug gap disappear. Solved by fitting two washers.
Have read somewhere on the net that NGK has stopped making non resistor plugs. Don't know if it is true.

Well somethings changed, heck for the first time in 40 odd years I bought a Champion plug the other day!
