Two are carb vents,.... they connect to nothing, but loop up above the carb into the frame tube, under the tank.
The one on the throttle side goes to the back of the petcock,... it directs vacuum to open the fuel flow in on and reserve position..

vents...

vacuum...

Test your petcock... it's probably bad from sitting so long...
Here's how...

I can't even put more throttle. It
Stalls out or acts likes is going to stall like if the carbs were getting flooded. Correct me if I'm wrong is hard to find the words to explain my situation since English is my second language.

this is the same as mine the bike ran fine 7 years a go and was just left in my dads garage and now it wont rev up nothing has been ajusted just the bottom taken off to clean out the old petrol

Fixing yours is simple, clean the carb.

You might try seafoam, drain the gas out, and fill with seafoam. Leave at least overnite, drain and pour into the gas tank. petcock to prime and start her up.

Sounds to me like the diaphram that actually admits the air and fuel when the throttle plates are opened is not opening. Stuck plunger or bad diaphram. Remember on a CV (constant velocity) carb the throttle plates a simply a request for engine acceleration, acceleration is controlled by the vacuum signal operating on the plunger that is sealed by the diaphram. Raising the plunger admits more air and fuel to speed up the engine. When you crack the throttle plates only some air is admitted leaning the engine to the die point. Max

You don't want to drain all the sea foam out,Try to start the motor to get the sea foam up in the carb. Just setting in the bowl isn't going to do to much.

It's vacuum controlled, but I would think it should go up enough to give full bore open.

Take the top off and check the rubber too.
