Been out fettling on the bike all afternoon, replacing damaged fairing and giving all the parts tucked away under it a good clean and polish, anyways one of the winter jobs I had on the cards was replacing the fork oil, what would be the best grade of oil to replace the existing with?, 5, 10 or15? also is a 2005 fz6 setup the same or similar to the FZS as I've never done this before and see there is a couple of great writeups about this on the forum, any help good or bad greatfully received.
