Whats the difference between the FE and the FG?
Not a lot on the outside. There are supposedly a large number of changes to the motor internals. One noticable difference on the ‘FG is the inclusion of a rocker-cover breather pipe that runs back into the airbox. However, going by the serial numbers and other details in the parts list, it appears that the breather pipe also appears on some of the later ‘FEs as well. One thing to note is that the ‘FE came in Red, Black and Silver paint schemes, but the ‘FG was only available in Red or Black.
