Periodically losing the ability to drive at full throttle?????
Periodically like the carb float bowl does not fill due to a vacuum in the fuel tank or restricted fuel flow?????
Take the gas cap off, stick a rag in the hole and drive it, does it still have the problem??
Is the fuel hose have a kink in it? did you try reserve to see if the main fuel line is restricted?

Subject: [Honda-C70] Acceleration problems after carb cleaning
After cleaning my carb, the bike starts much, much easier--although I'm not sure the choke was working at all before. However, I still have the hesitation/missing around 30-35, and I'm periodically losing the ability to drive at full throttle, accompanied by an occasional backfire. After a couple minutes of full throttle riding, I lose almost all power until I let off to about 3/4, then the bike acts like it has about 3/4 throttle. A bit later, I can go back to full. I found Mike's guide to adjustment that Chris sent me to, but I haven't done anything with the tabs to allow me to turn past the factory allowed adjustment range yet. The existing range isn't making a difference.
...and that makes me realize that I don't know if I've got that adjustment back to its original position.
