I might be able to help you here. We just finished a 500 s/s and used 500 unit triumph rings which are 69mm standard. They were perfect and just needed modifying at the ends. Remember four strokes don’t have ring stops…
We might even have a couple left.
email me at email@example.com if you aren’t already sorted out.
