I rode the bike for about 20 minutes until she was warm,
Let del for 15 seconds switched off waited two minutes then checked....

I have topped it up now and she seems fine

About the oil backingup into the air box is that somethng to worry about? And I'm not clear as to why so much oil came pouring out of the drain collector thing.... Surely it can't be right for that much to come out?

Thanks for all your replies btw! Much appreciated
