My bike wont start - what to do?

[Cola]

Yeah, that might be it as well. But it sounds completely normal when I turn the key to ignition. I hear the 2-3 second buzzing sound from the fuel pump, which should afaik outrule that being broken as a factor.

My mates keep telling me diesel start, easy start spray, ether, whatever, and that should make it go. I don't have any of those atm, so I'll wait until I've tried pushing the bike to a start when I get the new handlebars.

I checked the airfilter just now, and it looked like brand new. No dirt or anything around it or in it. Nothing above or beneath it either. Looked totally clean.
