   I had the TPS checked and reset twice. 2.5 (mV?) both times.

2,5 degrees, 423 mV.

Is the ignition map also a custom map?

I don't know. I assume not, since I was never told it is.

I've been around a while, and have never seen a center electrode completely disappear on a 4 stroke, They'd partially dissapear on 2 srokes, and the manufacturers came out with electrodes that would stand the gaff.

Something is going on, and I have no clue as to what it is.

... I wonder if a fuel map, functioning well on the Dyno, can get digitally lost (forgot to press ENTER kind of thing) and be automatically/accidently replaced by ECU stock info. It could explain a lot.... also the poor performance/top speed.

In that case the worst plug might have become THAT bad because of the spacer leakage, but would have shown clear signs of lean running anyway - like the other plug.

The shop usually steps up in cases like this. Because of geography it won't be easy to get anything done before next July. I will be able to check the plugs and establish if the spacer was the main cause for the destruction of the plug tip.

Just the positive electrode gone and the rest of the plug intact is new to me too.  Unbelievable that plug was able to fire.

Overheating?
Too lean mixture due to
1. squashed spacer
2. map too lean for that cyl, offset map mishap
?
