gwrightoy Posted October 26 Posted October 26 Could anyone shed any light on these small pistons. Approx 53.5mm diameter 50mm deep. Maybe JAP or Villers.? Number in photo. x3XC.M152.74-1061. Thanks Graeme Quote
Richard Farrant Posted October 26 Posted October 26 Hi Graeme, I think this may be a piston for a BSA 300watt charging set, the standard bore is 54.2mm. The part number look remarkably like a BSA number in same format as their motorcycles. Check the diameter across the skirt. Quote
