Interestingly, the (Copyright 2009) UCE manual calls for 195cc on the C5... but the (Updated on December 2010) EFI calls for 265cc + 2.5cc for C5. Those should both be the leading axle fork! If either one was correct for the leading axle fork, could the same be true of the center axle fork?
As others have found, the 2017 Euro IV manual calls for 430ml for the C5 under "Periodical Maintenance" Page-05, then on Page-82, under "Fork Oil Filling" it says 195ml for the C5. That is a center axle fork, and probably is the same as my 2015...but then again, who knows?
If you still have that 2014 link Haggis, could you also send it to me? I don't know if you can access my email address directly, but a PM will work fine. At least that would be the closest reference to my 2015 C5. Ideally, I would order a 2014 hard copy (since there is no 2015 version) of the manual but that probably doesn't exist, because after all... only someone who likes old school stuff (like an Enfield) would want one of those!
As I stated in an earlier post, the new Haynes manual says just to put back the same amount that comes out... and on that subject, what about the quantity that the factory puts in?!
Is that ever even close to correct, or is there ever anything close to the same amount in each side?
They don't seem to give a f*ck when they build these things,
why is it so critical to be correct now?
Of course, I want to do the best for my Bholenath, but it didn't seem to matter much to the factory.
From other research I have been doing, I believe there is no really true absolute amount of oil one should have. I think the factory recommended amount should be a good average, but that you may choose to have a little more or less to suit your purposes, (or due to being unable to find the one correct answer!). This is a very interesting, and somewhat amusing subject. It will be interesting to see what becomes of my 265cc 2015 fork seals over the next few months (at least), as I won't be able to get back to them before Winter. Once again, over 400 miles since putting the 265cc of Motul 15W in and all is well... so far!
