Picture Attachment problem (09 Jul 2022)
Due to the extraordinary growth of the membership and resources, we are once again bumping up against hosting limits. I am working on a fix. In the meantime, the forum should function, but you won’t be able to attach images. Working as fast s we can to fix. Thanks for your patience. - Makotosun

I put a thin amout of jb weld on the threads down in the hole, I will attempt to set the screw down in later today after it sets awhile.
I need to get into the tap retap. I need to put a second spark plug hole in a dt400 head for a compression release also.

I bought used good quality taps and dies and, together with my pillar drill, are some of the best buys I've made.

Stripped thread in the pilot air screw hole would be a 'first' as they're never screwed in tight. Was it all corroded & crumbling on moving the screw.

You can see where there is spot in the casting to put the hole.
I had to cut away part of a cooling fin that was going over it.
The shiny circle is the spot for the hole.
I don't think all the Enduro heads have that, I know my 250 does not.

I know it's silly.
But I hardly ever use the brakes on the 400, even less so with the release.

The screw or hole had no real corrosion, but the threads weren't grabbing but the screw looks fine.
I ran the screw in after the jb set all day, it took considerable force, I got it to bottom, the back out 1.5 turns and it stayed time, hopefully it holds.
