I had purchased a big bore kit from Eric for my 2001 RM125. It is complete; cylinder, head, piston, rings,circlips, power valves, etc. Just bolt on and go. I just purchased a YZ250F and the RM big bore / top end package is still sitting in the box. . Question,...Does anyone know if it will fit, ie;bolt right up, like it did on my 2001, to the 2004 model bike? Thanks!
