    As you can see, there are many variables to consider. More information would be helpful. Welcome to the forum!

    Yep,could be a few things and if it's EFI it would be other possibilities like IAC or sensor or broken wire....
    The more info you give,the better the chance of finding the problem:)

    There is a long history of problems. The 1000 mile maintenance they over filled it with synthetic oil, which caused it to blow oil. The bike was in the shop 5 different times for back firing, cutting out, leaking off the the rear motor mount, it would die when it back fired. Took it to another shop the idle was turned down too low,
    the seals had not seated yet therefore the synthetic oil was leaking. Road it like I stole it that fixed the leak. Still ran like CRAP! Cleaned up the carborater, replaced the diafram it ran great. Still blew once and a while. In 2010 my son started it after sitting for about 3-4 months, didn't let it warm up, hit the throttle wide open 3 times, bent the push rods. Decided to do a new top end. Just now got it put together. Won't idle without holding the throttle open. It was taken for a test ride and runs great. Diafram is good. I'm having a new carb kit put in. What is an EFI, IAC?
    Thank You for all your help guys!

    I would check to make sure that the needle is installed correctly in the carb. The needle needs to go directly through the slide, then the plastic (teflon) piece goes in then the spring over the plastic ( teflon). Common mistake to put the needle through the plastic piece.

    Since you will be in the carb, also look to see if the vac port in the slide has been drilled. The whole for the vac port should be 3/64". Double check that but I do think that I am close. If that slide has been drilled, replace it.

    Since you had carb off and did work clean out jets a small can of compressed air the pilot jet am be blocked

    Did you adjust idle air screw. If so turn in gently don't force closes just get it to touch. Back out 2.5 turns

    Then try and start and idle

    Since the carburetor sat for a few months there may be a clog in the passages that connects the mixture screw port, pilot jet, and front air inlet passage. Item #3 on the following page describes this and how to clean it out.
    http://www.cv-performance.com/harley-cv-carburetor-tuning-issues/

    Also, since this is an 06 model you can check the trouble codes yourself to see if you have a bad crank position sensor (common for that model/year).

    When you did the "top end" did you remove and inspect the intake manifold seals for deterioration? Also, when you reinstall it, you need to carefully and equally tighten the attachment hex bolts to ensure the flanges apply equal pressure on the seals. You could have a vacuum leak.
