I've got a Kohler K4620 two-piece toilet.
When the flapper started leaking, I replaced it with a Korky red "universal" flapper. This flapper didn't seal properly, so I went to the plumbing supply store for the OEM flapper. They could not find my model number on their computer and finally sold me a GP85160, which seems to be Kohler's "universal" flapper. They said that the float was pre-adjusted for 1.6 gal toilets.
Nope! The flapper closed in 1/2 a second at that setting, so the flush was useless. I moved the float all the way down on the chain, and it is better, but still closes too soon. I'm wondering if I should have gotten a GP87449 (same flapper w/o float). It sure seems like it would be a lot easier to install and give me a better flush.
