Looking at the specifications in the 1930 brochure: http://www.hendersonkj.com/ffo/documents/brochures/index.html both the KJ and Super X list their intake valve as 1 13/16 inches (not surprisingly since both the KJ and the Super X used the same intake valve). That works out to 1,8125 which is close enough for government work to your 1,826 so I'd have to say that's a standard valve. I don't know for certain what size valve the Super used, but I have a pair of intake valves here that are 1,875 (1 7/8 inches) and that seems likely what they were from. I believe A in the engine number indicates Alloy pistons rather than cast iron ones. XS means it was a Super Sport motor. There are also motors with L in the number. This seems to mean it was a low frame model. Some people think these are early 29 only (pre-Streamliner) but based on the serial numbers it looks like it was produced for most of the 28 season too ... Perry ----- ORIGINAL MESSAGE FOLLOWS ----- Hello! I have measure my inlet valve to 46,4 mm/1,826 inc. Are this a standard or super sport valve? Some Super X have A on the engine number others have XS. What are the difference? Sigurd |
