zekibanshee Posted September 18, 2012 Report Share Posted September 18, 2012 just bought a 4mm crank it was suppose to be a short rod and it turn out to be a long rod. Is there a way a can measure the stroke to find out if is really a 4 mm crank Quote Link to comment Share on other sites More sharing options...
Wildcardracing Posted September 18, 2012 Report Share Posted September 18, 2012 Measure from the crank center axis to the rod pin center should come up with 29mm or 1.142" if it is a +4mm crank Quote Link to comment Share on other sites More sharing options...
