josef9177 Posted February 17, 2015 Report Share Posted February 17, 2015 Hi all I bought a wsm platinum series banshee/rz 350 64mm Pistons for my rd 350 aircooled. But unfortunately when the Pistons came there is no manufacturer recommended clearence on the package. When I asked the ebay seller about clearence I got a reply of .0030" to .0035" of clearence which I believe is for liquid cooled motors? Since I plan to use it in a aircooled rd 350 with a cast iron liner what clearence should I run? Thanks Quote Link to comment Share on other sites More sharing options...
