Wrist Pin Installation ???
Please help with this one : I'm in the shop about to put the new piston , wrist pin , clips , rings and cylinder on to cases and I noticed the wrist pin differs from one end to the other end . One end of the pin is solid whereas the other end of wrist pin is hollow , (same as original pin ). I can't imagine why unless it has something to do with allowing air to move through pin for cooling ? Question to all of you out there is which end of wrist pin do I orientate towards the exhaust port , the solid end of pin or the hollow end of pin ? Also does anyone know the reasoning behing this design ? Your help will be appreciated as I'm trying to get this thing finished up .
