1974 Honda CB360 cannot maintain power when riding?

I just recently got my hands on this bike it has been sitting for atleast a year the first things I did were.

-Checked the tank for rust (it was clean) had some gas in it but was drained and added new fuel
-Checked the spark plugs they looked ok
-Took the carb off and cleaned it out, did not get a kit yet just looking for suggestions first.
-Checked the Throttle cables they move freely both forward and back.

The bike starts up after a few trys with the electronic starter. It idles ok after a little adjustment on the throttle.
I can rev it up just fine when it is sitting (no smoke)
Once I throw it into first and attempt to take off it will go with about half power or less even at full throttle.
At times though, I can get it to ride fine for about 2 minutes then out of nowhere, its as if the engine is getting no gas even though my knuckles are pointed to the sky.
Then I have to quickly enage the clutch or it just cuts out and then even sometimes it will just cut out.
Then I have to have the throttle half open to start it up again.
After starting it sometimes it just won't give any gas with full throttle. I just keep reving the grip and eventually the engine starts to respond. Other than that the engine is not misfiring and yes I understand its a 35 yr old Honda, But I'm not giving up yet.

This is my first Motorcycle and I am prepared to put forth the effort to make the ol girl go like she once did before.

In honesty I am no motorcycle mechanic however I am capable of performing most repairs myself. The only suggestions I have gotten so far are to replace the rubber pistons on the accelerator pumps on both sides of the carb.

Would this solve my problem?

Any suggestions would be greatly appreciated Thank You in advance.
 
You said you cleaned the carbs, but, the problem you describe does sound like carb trouble. I have cleaned a number of carbs that someone else supposedly had "cleaned", not to insult you, but, this may be one time you need some expert help. If you have a shop clean them for you, you could save money by pulling and reinstalling them yourself, good luck.
