How much oil has yours used during run in ? and did you run it in by the book or more briskly?
I have now done 300 miles & it has used not a drop of oil.
I have not thrashed mine, but I have ridden it how it feels happy i.e. regularly to 4250 - 4500 rpm (even after 50 miles) and up to 5000 sometimes. The engine has been very smooth from the begining.
