Default Throttle Body Cleaning, first time?

I don't mean to piggyback off the thread just posted about x-bikes but im going to be installing a new air cleaner on my bike in the next few days.

I have a 2005 Vegas and I just recently(last week)installed RPW Slash pipes and a VFC-III fuel controller and everything seems to be running fine. It rarely, if ever back fires and the acceleration seems fine even though I don't have much experience as this is my first bike so I don't have a lot to compare it too.

I ordered an S&S air cleaner which should be here today and I figured I should clean the throttle body while I have the tank and air cleaner off.

What should I be looking for on the throttle body(dirt? soot?) when I get the stock air cleaner off?

Also, how should I clean it and with what? what are the do's and dont's?

Last question, will i need any new gaskets that I should get from the Vic dealer when I pick up the S&S cleaner? Don't want to pull it all off then realize im gonna need new gaskets or other parts; im trying to save myself an extra trip.

Again, this is a 2005 Vegas with the 92 c.i. and I just hit 12,000 miles. The last dealer service on this bike was the 10,000 mile service which was done back in 2008!!!

I have not installed a new air box on mine, but I don't think you would need any gaskets from the dealer to do so. I cleaned my throttle bodies not to long ago. I used a toothbrush wrapped in a cloth diaper. I sprayed carb cleaner on it and scrubbed it out. It actually was not bad. It was a little carbon build jut under the butterflies. It only took a few mins to do. I did notice the idle go up afterwords. Open the butterflies up with the throttle and put a flashlight on it and you will see the build up. There was none on the air box side.

I have the 92CI too just on a kingpin.

I recommend reading this: http://www.thebikersgarage.com/victo...body-cleaning/.

Please add your bike's year and model to your signature. Here's why.

Just out of curiosity, back when I first started driving, I owned a car with a carburetor. I would remove the air cleaner, throttle up a bit, and spray the carb cleaner directly into the butterfly. It would cause the engine to bog down but if you didn't spray too much too fast you could keep the engine running.

Not being much of a wrench (so no flaming please ), was that:
1. OK for a carburetor but not for fuel injection
2. Cleaned the carburetor but not as well as using the toothbrush and cloth.
3. Cleans both a carburetor and throttle body but not good for the engine.
4. Other

The stuff is too hard on there. The cleaner alone will not remove it without a little brushing.

Goatlocker, to do it without removing the gas tank such as trying to use those vacum ports on the right side would be a pain I think and you cant ensure you got them spotless, it actually is a pretty quick job once you do it once. I didnt have the cool link Crossroads provided my first time and it easily became routine. I do it ever other oil change and yes, it makes a differnce.

Cool Blue/Fed, I found SEAFOAM has a spray cleaner as well as liquid for the fuel and it works great!

Only thing I will add is I like using a set of mechanical fingers inside of a sock along with the tooth brush. This also helps to push more sock in the TB for that final spray to help soak up some of the mess from going in the cans.

Last thing I would add (im not for sure if this is on the 100 but on the 92 it is) there is a vacum port for CA emissions located on the right side of the TB and that rubber cap has a history of dry rot and causing vacum leaks. Inspect and replace if needed.
