I know the 848 is higher compression, but I can't see any difference between the two. | | | | | Joined: Oct 2001 Posts: 3,458 Extreme Gabster | | Extreme Gabster Joined: Oct 2001 Posts: 3,458 | I don't think there is any other difference except maybe the drilled passages for the rocker arm oil supply.
