Hi, how are we all? I ran out of petrol last night and had to walk my bike home. When I got home, I filled it up with some more petrol and the bike now won't start/stay on even with full throttle. I'm not sure what the problem is. It is not backfiring... (yet?) I think the carbies need to be cleaned. Can someone please come over and help me clean them so I'd be able to do it in the future by myself? I would greatly appreciate it. My bike is a 1993 CBR250RR Repsol.
