I should also mention that the skirts on the Harley flathead pistons were a little too long and hit the crankcase baffles. You can trim the bottom of the pistons. In my case the baffles were pretty broke up so I just removed the remaining baffle reminants. I used the cast iron oil control rings that came with the pistons and it runs great.

afternoon, may try Eastern M/C Parts in Blackville S.C. or V-Twin in NY
taiwan made UL pistons that you ll need to trim 150 thou. off the bottoms. then you ll need to decide whether or not to run the expander ring under the oil ring. good luck.gww57.com

The expander is a good thing. It helps support the piston to prevent rocking in the bore. A taper ground piston gets its support at the bottom front and rear. The expander helps central the piston at the top. No real cons with the expander.Last edited by harleytoprock; 08-23-2012, 09:18 AM.
