Accelerator pump timing

Has anyone done the timing mod only (checking that the squirt doesnt hit the slide) and noticed a gain in performance or power delivery??? I have a 01 WR426 and it runs perfectly from top to bottom... SO I dont really want to open the jetting can of worms yet...

many WR/YZ's have hosed APJ timing and duration. You have EVERYTHING to gain, by at least CHECKING IT OUT!!
