johnnynhl Posted August 13, 2009 Share Posted August 13, 2009 Hi All Can anyone tell me what size of pistons I have, they are marked 3H5 on the crown. No other idents, I thought it should have been marked STD or + something. The bike is an 1100 US Import of 1980 Vintage. Thanks Johnny Link to comment Share on other sites More sharing options...
