I was driving my Cbr600F2 on the high way one day and then it sounded as though it was running out of gas and bogging so i switched it to the reserve and so i kept gassing it and flooring it and i couldn't hit 75 and was going 60 so i switched down a gear trying to keep my rpms high and then the same thing would happen so i was stuck going 50, did i blow my headgasket?

 

could be a head gasket or it could be something even more simple kink in the fuel line or carb needs cleaning it could be simple as that or the head gasket which will be kinda a bitch to replace cause you have to remove a lot of stuff honestly start at the simple stuff bleed the fuel line check the carb that stuff is very simple if you dont know how to check youtube there is videos for everything

 

Check the r/r on the bike for heat sign. Check the connector as well.
If the regulator/rectifier over-heats and/or starts to fail, the bike will be getting poor
ignition spark. That will exhibit similar signs to low/no fuel. If, after the bike sits for a
few minutes, it starts up and runs fine, that's probably the issue.

Here's a couple of links to further explore the possibility...
