hey guys i am having some weird issues with my bike. it was running great untill my throttle cable broke. after i replaced my throttle cable and my spark plugs since i was in the area, my bike has a hard time getting started. i can start the bike giving it a bit of throttle, but wont stay running, almost sounds like its not getting air, cylinder number 4 is only carb sucking in air hard

 

We're you super careful replacing your throttle cables? Carbs are quite delicate and will preform poorly if something gets bent or damaged.
I'd reccomend pulling your tank/airbox off and having a good look at your carbs and throttle cables... Something might be out of place, bent or a kinked hose. Also a good time to check your ignition leads are in the right order.

I just thought of one more thing. Check your idle, you might need to turn it up. If your previous throttle cable was set up with no free play it would hold your idle up. Then when you replaced your cables you would have corrected the freeplay and lowered your idle. Turning your idle up may fix the problem.
