I have modified my 2003 GL1800 with the reverse fan modification using "Electric Fan Engineering" fans. These work great. However, I am going to upgrade to the larger radiators from 2006 and above. The radiator shrouds are 1.5" larger in diameter. My EFE fans do not fit this shroud. Can anyone tell me if the fans from 2006 - 2013 (all have the same part number 19030-MCA-A61 are larger than the 2001 - 2005 fans (19030-MCA-003 and 19032-MCA-003)? I have heard that the older stock Honda fans mount straight in the new shrouds, but is the fan diameter larger on the newer models? Also - has anyone done the reverse fan modification on a 2006 - 2012?
