RE: YS 170 spinner adapter - which is the better locknut
Jon,
Here is the adapter that I use/d when I was using YS: [link]http://www.truturn.com/cgi-bin/store/agora.cgi?exact_match=on&p_id=tt0814a&ppinc=adapt[/link] Ran this on my 170 last and that was actually taken off my 140. Everyone at my field also runs this on their 170's.
