There is a seller on eBay who has replacement screw kits for many of our old enduros. Someone will come along and direct you to him. I can’t think of it at the moment and have never used him myself.  Not yet at least….

I've purchased a few times from Motodad on ebay, he's a good guy.
In my experience the head height is less than the original screw, depends how true to original you want to keep it.

Least everyone thinks this project slipped into the basket case never to be running again category, a few update pics on the frame/misc parts.  Other things got in the way, and my powder coat oven needed enlarged to fit the frame.  But that is over the hump now.

Machine shop said they could not get piston nor the crank bearings, so I need to source those and get them to the shop so they can bore to fit.

Pleased with how the frame came out.

Then strip and prep

And some results. Not bad considering where it started

Not sure this powder coat color does as well on the silver, but its not too bad a match.

Still much to do... one little step at a time

Last post was 2022.... smh. And the engine has sat here all this time.With some help, made a push over the hump. Here is current status/pics. Turns out the piston was the wrong one so I need a 125'B' piston oversized. (was bored to clean up). And some seals.I have to say the case parts cleaned up nice.

Hmm... pics not working

You need to use a 3rd party hosting site like imgur to post pics here.
