Anybody know if Harley made and still sells a 10 over piston for the XB9? Parts manager at American Harley in North Tonawanda spent alot of time looking for me but couldn't give me a difinitive answer. He looked up pn 22246-04 based on stock pn and normal iteration HD uses for OS pistons and the system came up with a valid pn but he was just taking a guess on the pn. Anybody know for sure?

Why 10 over?
Heres a link for over sized pistons, i see a +0.015in. Seems though they all get compression ratio bump to 10.5:1( this is stock for 9 engines i believe)

Might as well big bore it bump it up to the 1050cc
