I started taking the bike completely apart.
When I got to the point where I needed to pull the fly wheel off I realized that I do not have the correct puller.
Here is a pic of the flywheel on the bike.
It uses a very non standard thread.

So, I went to my parts catalog to order one and no such puller was available.
So I contacted ATK, gave them all my info and ordered a puller.
They were not even sure they could get one.
It's been a few months now and I am tired of waiting so I decided to make my own

The first step was measuring the thread pitch and diameter that I would need and ordering the correct size tap.
Then I went to a local machine shop and gave them a print of what I wanted.

Of course the print I gave them has the measurements

After I get the puller back I will post some pics and let you know how it works.
