my yamaha 650 starts, but wont rev?

Im the crazy donkey who put this bike in a ditch, underwater.
but pulled it out later and got it to start that night.

My problem is, after its starts, i give it gas, and nothing happens, just makes a bogging sound.
my spark is good, i dont have points on this year motor and the timing has been idiot proofed so it really cant be changed.
went through my carbs three times thinking its a fuel thing, but they looked pretty damn good. flushed the tank till clean, and xleaned up some corrosion from when it went under.

its an 80 xs 650, transistoriized ignition, unadjustable mix carbs and a nontampering timing(right).

im missing to much summer, any ideas, anyone.

water/moisture in the crankcase?? bad lubrication due to fudged up oil?? Im not even sure why putting it in water can offset your timing, unless its electronically controlled by one of the new fangled hall effect timing systems.

apparently, the rebreather tube from the engine must be connected back to to filter boxs or it wont accelerate.
i wish i new this a month ago
