fuel/air mixture?

[Dead Eye]

I knew mine was over-fuelling before because it would bog down a bit at higher revs and didn't pull anywhere near as well as my previous Fazer. After the adjustment its running a lot better but I still have the starting issue.

I changed two plugs a couple of months ago and that seemed to help a little - I would have done all 4 but the two inner ones (on cylinders 2 + 3) were quite tight and I didn't want to risk snapping them
