Gents... quick opinion poll on oil usage... I've had to top mine up today quite a bit and it struck me that it hasn't been long since I last had to. I've no scientific measurements yet but will monitor as of today to come up with a firm idea of how much I'm using. I'm just coming up to 6k on this bike since it was replaced in August. There are no leaks so it must be burning a bit. The old blades were notorious for getting through oil, and my last gixxer used a bit too, but anyone got any input as to how much you are using?
