    Up until two days ago when I rode in a rain storm, my bike was running fantastic.

    Now I have this issue where at Idle it purrs like a kitten but when I go to take off from a light she boggs from 1k - 2k then accelerates as her normal awesome self. I cannot for the life figure out what is causing it.

    like a blahhh-VROOMM! When I give it gas.

    take a close look at the spark plug wires when the bike is running in the dark. you may have a short to ground.

    Both of my XJs did this all the time.
    With one of them, this issue seems to have disappeared after I rebuilt the carbs. (The other one I haven't used for 3 years now, so this bogging is propably the least of its problems)

    I can't explain how a rainstorm would influence the carbs.
    Maybe the wet / cold created a vaccuum leak?

    how's your battery, under 2K that's what your running on.
    if you can find a cooler pipe, slowly pull that plug boot up away from the plug a 1/4 inch. if you hear the spark inside the boot and the miss goes away the plug is bad if you get shocked see cyclenoob's post

    Thanks community! IT was plug wire #1 was splotched with oil from my leaking valve gasket (yes this is getting fixed soon) I wiped it all down and reseated the wire on the plug and VROOOOM! no hesitation.

    Thanks again all!

    Good that you fixed it.

    Good videos of plug wire arcing, obviously easy to spot in near-total darkness:
