Z1R Valve Adjustment and #1 Spark Plug Fouling Issue

A day of small details.

It looks like progress but it’s not really… Well, at least we got the engine to start.

Oh! The cap might be coming loose…

To verify the feeling, I measured the depth on the cap side…

I’ll mark it precisely with a marker.
Up to here, around this area—if it goes in this far, we’re good.

Drilling a pilot hole in the insertion area makes it screw in much faster.

It’s gotten a greenish patina look.

Since it’s the old mounting method, I’ll switch it over to terminals and power cable.
