I was told that this part number has been discontinued, does anyone have any idea on the replacement part number?
Also, where is a good place to order Sealed Power rings from? My web-fu only led me to one online source, who told me the number was discontinued.
Do the Hastings rings work equally well for Nikasil 1000cc airheads?
Thanks for any info.
