Sounds like water in the gas. Bad gas at an old filling station can be the source. More likely is simple condensation in the gas tank. Drain the carbs if not fuel injected and also drain some gas from the tank.

Either take the carbs off and clean them or add some fuel additive to clean the system. Sounds like you have a clogged jet.

6500 rpms? Just how fast are you driving my friend?
You have serious fuel issues (not to mention the need for speed issue). Your trouble is in your fuel delivery system. ... probably too much.
