R100GS exhaust nut

[arptra]

hello all, does anyone know where I can get a thread chaser for head to clean up the threads for exhaust nut?

I used a metric thread file after I had to cut off an exhaust nut. Then, I used a good nut and some WD40, and that cleaned things up for me real well.

Any specialty tool house could order the metric die. I forgot what the pitch is...probably something like 1.5mm. As for diameter, 52mm sticks in my head.

S Meyer has them.

Or the metric thread file if the threads aren't too bad.

McMaster Carr (check out on internet site) has just about everything known to man.

Also, any supply house that would be a supplier for machine shops, tool & die makers.

Be sure you know the thread pitch - in metric, it is the dimension from one thread profile to the next. In english, it is threads per inch.

When you say "clean them up", do you mean the threads are damaged and you want to run a tap over them, or are they just dirty with build-up.
