As I've said (in other threads) before, mine uses about 80mls every 1000 miles or so,
I can stop that, just by slowing down and not hammering the bike so much, but I like doing
(I recently went 2500 miles without any oil lose, just to try, bit borring though)
the SV lump is fine under normal use, but you have to expect a bit of oil consumption when you hack it.
