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.

Why would you have to clean the throttle body unless it sat for a very long time. I'm just trying g to get a lesson out of this.

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.

Thanks John.

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

With the rain tomorrow it might be a good project.

Oh brother, hope it don't turn out like the tranny plug, too soon no I ain't

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.

Or my tiller

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.
My garden isn't that big so I just turn the soil over with the BH,

K&N's are the way to go I have them in everything I own that they make them for.

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.

One thing to note with K&N style reusable filters. When you re oil the filters, especially if you use a little too much. You start the bike, the air pulled in through the filters will suck in (or off the filter) any extra filter oil. That oil will stick to the side of your intake and sensors. So going easy on, or using the correct amount of filter oil will help cut that down.

Your fault bringing this thread back up, Kiwi...

I'm going to disagree with removal of the FI. Here at Club Spray my butterfly with choke cleaner and a cap or two of inject this shit with my gas, I just don't see mrs. homemaker out in the driveway; pulling the throttle body off the family car, using the same gas, same sensors, same-same... get back in the house.

Same on you!
