SOURCE: have to flush 2 or 3 times to empty toilet bowl

hello, this is a standard toilet you will need to inspect the flapper that is the rubber flap that holds the water up in the tank it works when you pull the lever it pulls the chain upward and lets the water flow if this flapper is old it may not stay up long enough for the water to flow. open the tank top and flush the toilet see if this flapper is staying up long enough and giving the tank enough time to empty if not change this rubber flapper its inexpensive part.
if this is not the reason then you need to adjust your water filler valve there should be a small screw on top of the pivoting float arm
if you have to adjust it for the water limit line inside the tank this will be the proper amount of water needed to flush once completely

also check that the chain lenth on the pull lever is not pulling the flapper down quicker than its supposed to,

try this let me know your results
hope it helps

SOURCE: Toilet Refills Every 15-Minutes

I have minute amount of leakage into the bowl causing mold to grow. I believe that it may be the rubber seal for the flapper body to the porcelain.

SOURCE: Toilet will not fill up

Some Toto fill valves have a plastic debris screen located at the inlet connection. Turn off the supply valve and remove the supply connection at the bottom of the tank. Use a mirror to inspect the screen for debris.
I agree w/ Smithbrother, the Fluidmaster fill valves are cheap and work well. The only thing they ever need is an occasional seal for $1.50 and 5 minutes to replace.

SOURCE: valve adjustment

You need to replace the flapper and you will need to purchase one specifically for the Kohler toilet. I have the same toilet and tried using a generic flapper and from experiance, it didn't work until I bought the correct one and I'm a plumber! Have a great night.

SOURCE: Kohler one-piece has no flushing power

Don't flush more water! Trash the toilet and replace it with a toilet that uses less water and flushes efficiently; practically every manufacturer makes a dual flush or eco model. Spend your money on a good toilet rather than paying for and wasting water every day.
