Remove the air filter and spray some Starting Fluid into the intake while cranking - any sign of life? If so, it confirms a fuel issue of some kind.

Because it's F.I. it may be something that you can't fix yourself if that's where the troubleshooting leads.
cool thanks man. Yeah that's what I'm afraid of. Don't wanna take this to a shop and spend tons of money on labor!

For the CBR, I would run Rotella T5 semi-synthetic in 10W-30. 30 is the recommended weight for that engine, and T5 is a good choice IMO.

Honda GN4 10W-30 doesn't test out that well from what I've seen.

I don't think the oil change interval has anything to do with the issues you are having.
Yeah I'm going to change it much more frequently now.
