    Sorry can't help Mike, had almost every other problem with 08 EFI, but throttle body ain't one of 'em. Knock wood.

    Strip the T-body of all its removable parts. Use " Brake Kleen" or an equivalent spray solution. Clean inside of t-body. You can take the injector nozzles to a car shop who has the means to clean them, or you can make a setup to handle that.(Prolly won't pay unless you're going to go into business in that area). Check fuel pump pressure. Reinstall parts, and you should be good to go.
    Don't forget new seals throttle body to heads.

    Many times I find an oily mess coating the inside of the throttle body.
    Look in your throttle body, and if it's clean, skip that part of it.

    You may want to check your Street Glide also. Especially with the shitty Harley breather system.:oops:

    When you take your throttle body out or don't. Remove the IAC stepper motor and clean that area also. There is a small hole that runs from the stepper motor housing diagonally back into the throttle body. Clean it with a Q-tip and some brake clean. Be care full not to clean the map sensor or the IAT sensor with brake clean.

    You have that Kabota dealer right by you, drive the tractor out there and pick up a new one and tell Dale you got it back together and gave it a paint job. :D
    My garden isn't that big so I just turn the soil over with the BH, :old2:

    Do the EFI bikes have that crankcase breather running to them like the carbed models? If so, rerouting to a puke can or check valve down low, and plugging the port where it attaches to the TB, like we do with the carbs might help it stay cleaner..
    Just a thought.
