I have a 2004 cbr600rr, I recently had a little problem to start my bike engine that I have to press the electric start button more than once or twice before the engine could be running. I am sure is nothing to do with the weather and hope you guys could give me some help.

 

When is the last time you did a tune-up? Could be spark plugs or fuel delivery issue.

 

weak battery maybe?

 

Spark plugs. Or sending unit for the ignition. You can search the part number or go to your local dealership.

I doubt it's a weak battery, but that's an easy place to start.
