Anyone have a die nut to run down the exhaust nuts on a 3 1/2? I checked back through the forums and a couple of people tried this and wondered how they got on.

Re: Nuts!!
I have both a tap and a die and use them as and when I've scruffy exhaust nuts or exhaust ports. I've several 350 bikes and several 501 bikes (which use a larger thread). I believe using the tap/die does help improve the ease of the nut fitting into the head.
I bought the tap and die on eBay, there are some that are tolerable prices and others that I can't justify paying even though they may be better quality tools. I seem to remember my tap was relatively inexpensive. There are occasionally sellers who have a used item or a one-off they sell cheap.
To provide context, I buy tools whenever I have a reason to do so. Your needs and habits may vary.

Re: Nuts!!
Could you kindly post a picture? I don´t have any idea of what or how is a die or tap
Re: Nuts!!
Norbert, tools for cutting threads. Tap for an inside thread (nut), die for an outside thread (Bolt or screw).

Re: Nuts!!
In the first instance, save yourself some money by modifying an old exhaust nut to do the job.
Photos of mine attached- cut into the thread at 90 degrees in 3 places around the nut and then file a lead in to the new edge.
Will do a pretty good job of cleaning up head threads and significantly reduces the risk of cutting a cross thread which you might do with a tap.
Obviously if the head is really mullered this won’t help much but then a tap probably wouldn’t either, unless you’ve had a insert welded into the head and need a completely new thread (at which point you may as well use an expert like Paul Compton to to do the job for you)

Re: Nuts!!
Of course I’ve just re-read your post and realised it’s the nut you want cleaning up not the head… but the above info may still be of use to others
Re: Nuts!!
Thanks for the aclaracion!
The easiest way trying to save a nut would be a thread file, a very useful tool anyway
