skishop69 Posted June 10, 2006 Share Posted June 10, 2006 I was told that the EA81 had a forged crank and rods by the guys at RAM. If this is the case, does anyone know if the same applies to the ER27 since it's a larger offspring Link to comment Share on other sites More sharing options...
calebz Posted June 10, 2006 Share Posted June 10, 2006 The ER27 is not the larger offsrping to the EA81. It is however similar to the EA82, which, as far as I know has no forged parts. Can't speak about the EA81, since I have only owned one and never worked on it. Link to comment Share on other sites More sharing options...
skishop69 Posted June 10, 2006 Author Share Posted June 10, 2006 Actually, it is. It shares the same bore, stroke, and bearing size. It just has two add'l holes. (1.8/2=.9 1.8+.9=2.7) (though more closely related to EA82) Link to comment Share on other sites More sharing options...
