I cleaned the injectors on 2006 yamaha vstar 650 got a little more power but when I open full throttle and release it some it is surging what could be making it surge now?

Your idling jets works well, but your throttling jet may have blocked in it. open the carburator and clean it.

idle cable out of adjustment and or throttle cable needs adjusting also and they always need to be lubed at 5000 miles adjust throttle cable with wheel striaght forward idle cable to all the way right lock and 2-3mm free play on throttle grip

Stars seem prone to fuel system issues, mine keeps me amused with its antics. I usually take it for a good romp now and then to show it who's boss.
I'd suggest changing gas stations to avoid the ethanol additive which causes gumming up of some fuel lines, disintegration of others and somehow manages to hydrate the gasoline to where it burns irregularly. Additives will be your salvation if you can't escape the ethanol.

this symptom resembles an intake leak. Check to see if your intake seals are not leaking

it sounds to me like clogged jets in the carb u need to take them off and clean the jets with a peice of small wire pull a peice off a wire wheel it works best for the polit jets (small ones ) get a digital camera and take pictures as u go if you are not sure that way u can refer to them if you get lost good luck

poor tickover is in the pilot circit. does it smooth out at half throttle? what condition do the plugs show after a long tickover?
if you didn't really really clean the carbs (full disassembly, all ports checked for good continuity) then go back and take them apart.
