Good point Martin, thanks.

I put some masking tape around the throttle where it butts up against the light switch housing then put a piece on the switch housing too. Put corresponding marks at zero throttle, then twist throttle to full open and mark that position on the throttle, then divide into 8 segments from zero to WOT [wide open throttle], then you can do your plug checks at set throttle positions. Plug chops best done on a decent road with frequent laybyes to use. Hold throttle at set point, switch off ignition, immediately pull in clutch and coast to a halt, preferably in the laybye where it should be safer to remove the spark plug, that gives a snapshot of the plug at the time of switching off the ignition. Ideally you'll have held it at the same throttle position for at least a couple of minutes.

Thanks Martin........what you up to today........

Doing plug chops would have been a better day than digging out a tree stump.

Doing plug chops would have been a better day than watching the Cup Final

Fair point.....

Thought you'd be watching the cup final, mate? Oh, sorry, don't suppose you wanted to be reminded of that

Even digging out a tree stump was preferable to watching that FA Cup performance.
