Oops!
Information is very confused for the various fork designs. I was actually going on a friends advise and I believe he does have the leading axle...
So far they're working great! I suppose I'm risking blowing my seals? Just did a 300 mile ride and no leaks yet...
EDIT; I just looked up my notes and I actually had varified in my Factory Service Manual, page 02-7, 265 ml +2.5 (?) for E5, G5, C5. Of course, it says on the cover; "updated December 2010" and shows leading axles in pictures. Doh!
EDIT AGAIN; Might I ask your source of information Haggis, which indicates 195 ml?
The new Haynes manual just says to put back the same amount that comes out, lol!
Ducatti Scotty's write up says 190 - 195 ml, and that was based on comments from the Indian Royal Enfield Forum. As I remember, Scotty said, that they said, if you go over 195 your seals will (or may) leak...
ONE MORE EDIT AGAIN; I just went out and looked, definately no leaks and about 400 total miles since oil change. I also re-read Scotty's write-up which was at least based on his leading fork C5, and was written in 2011. Not sure if they had the straight bottom forks yet in 2011?
