How To, Harley Davidson Throttle Body Cleaning. 

Always appreciate your tips and step by step how to videos

Really appreciate how you take good of your machines,plus I am starting to get addicted to your very informative videos!

Really enjoy watching your videos Rocco. You got a great way of gently talking viewers through the process.

I just did this maint on my 2005 FLSTNI. Your video was spot on as always. Tanks Rocco!

Thank you for sharing the knowledge. I like your number one rule: "Don't get crazy"

Always watch your Harley related content. Very informative, keep them coming.

Great vid. Vented the heads to a catch can and everything is much cleaner in the air box

Good to see you back making content!

That’s my “Blue Bird” I have a 16’ Road King “Cosmic Blue” I get complements everyday I ride which in Houston area,, I’m able to ride 9 out of 10 days,, hot, but sunny. Thank you Rocco!

Nice job...beautiful bike. Thanks for sharing 👍

Hey Rocco, top tips as usual. I have a base gasket to do on my sporty, and cam tensioners on my Dyna, if I get in a clinch I will tap you up. Cheers Rocco.

Great Video as always 👏🏼👏🏼👏🏼👏🏼👏🏼, keep it up Roco✌🏼✌🏼

Excellent video, thanks for the good information.

Nice. Just encountered the same issue on my 2010 Electra

Love it rocco!

Well sir, another wonderful video. Thank you for sharing. I like your channel b'c you seem to work on Road Kings of the ilk I have. I purchased my 1st RKC (2006 Inj. w/38,000mi) from an original owner in 2021 (early Fall). The bike was great looking and mostly mechanically sound. The speedo didn't work but I wanted to replace it w/ the new version 600 LED light scheme & tack speedo anyway. I changed the speed sensor as well and she's working fine now. The gas gauge didn't work and I tried the pump assm. but, although the schematic shows the float included, it didn't come in the kit and had to send it back. I replaced the caps w/ the Blue LED Harley version and although the LED's do come on, they all register at ignition and turn off one by one , leaving only one of 5 on perpetually. Even when the tank is 1/2 or full. I have a fuel sensor unit on order but it's been on back-order for 3 months now and the new ETA is May sometime. :( I did several preventative maintenance actions (oil, trans fluid, new gangster whitewall tires & balance, LED Headlights & Fogs, new windshield & tinted the lower 1/2. Lastly, a brand new 1-1/4 diameter Lindby Magnumbar) w/ the help of many of your video's !! Thanks BTW !! :) I'm glad to see the care needed for the air cleaner in this video as well. But, I sent it in for a for a 40k service to Cowboy's HD (Beaumont, TX.) Great dealer btw. I'm actually a Louisiana boy in Leesville, LA. and Taboo HD in Alexandria, LA. is only and hour away. But, I wouldn't send my worst enemy there. I like Cajun HD in Lafayette, LA. but they are 10 min farther than Cowboys so , there's that. I do business w/ both and happy they are w/in 2 hours of me. Anyway, Cowboy's thought it was a wonderful bike that was taken care of well. They confirmed the guy I bought it from was the original owner, complimented me on the up-grades I made and gave me a T-shirt & a couple of poker chips for me and my riding partner (Doc, w/ his new, used but only 1 owner 2017 Street Gliude) He's a 21 yr Ranger medic vet w/ 9 combat tours. One tough hombre and president of our III % riding club. However, they did find the clutch plates were shot. I had an idea they might be b'c after riding about 6 mi the bike would try to seize or bog down and struggle to move when letting out the clutch. It would change gears but struggle to move. The plate were getting hot and seizing to each other. Once cooled I could drive it a bit again. WE CHANGED THE CLUTCH PLATE ASSY. and been on several small 3 or so hour trips w/ zero issues. I'm one happy camper as they say :) If you have a t-shirt, and /or can get me any white longsleeve XXL t-shirt w/ colorful logo from a dealer near you and their poker chip, I'd love to send you the fee :) Just a thought and don't think twice if it's too much trouble :) Thanks again, Sincerely ........................

Might be better practice to blow compressed air from the inside (as best you can) of the air filter. Blowing from the outside will typically jam dirt further into the element.

BEST PERIOD.

Thank you 😊

Love the video’s too

Thank you for this! I’m noticing some hesitation in throttle response here and there w/ my Road King…I’ll try this first before taking more extreme measures. 👍🏼👍🏼

Thanks!!

Nice Bike !

as always very helpful thanks. one question your opinion on an external breather kit

Cool content 👌 😎 👍.

I see that Vet sneaking in the background 😎👍🏼

More preventive maintenance for longevity and avoidance of breakdowns . Thanks Roc

I swapped out air cleaners and when I pulled the old one there was oil on the breather bolts and oil on the screws that hold the a/c onto the throttle body. I'm gonna used q tips to clean the threads before I install the new a/c with blue loctite. Could I use something else or soap n water w q tips? Thanks much. Your channel is awesome. Common sense and explained perfectly.

What is the difference between Berryman B-12 Chem Tool Throttle Body Cleaner and Berryman B-12 Professional Chem Tool Throttle Body Cleaner? Love your videos. Keep 'em coming.

Beautiful Bike.

I can do this also on carb with the spray?

My 2003 883 air filter seems to drip some stuff out on to the exhaust bar under it. What would cause it to do that???? Is it running to high or something???

Do you have to pull the map sensor to clean it . Thank's for your time.

my 2010 883 sportster runs good, idles good. But, even after riding an hour, I can stop for 15-20 minutes and when I start it up it will idle at 12-1300 rpms for 2-3 minutes before it settles down to normal idle. I have replaced the temperature sensor on the rear head. It shows no error codes. have also cleaned the the throttlebody and IAC.

Open the throttle with bike off and use a brass brush with the spray to clean butterfly area...! .....Nice ride"

Should you remove spark plugs after and clean or replace them

How about that C2 Corvette in the background? What year is that and what engine is under the hood?? Also, beautiful Roadie. I have a Heritage now but want to get me a newer Roadie in the future.

Revving the engine and opening the throttle body with out the cover on is safe for the engine? Granted I noticed you didn’t crack it wide open.

Can we use WD 40 for cleaning iac system

Can those filters be washed?

Hey Rocco love your videos !! I was hooding you can give me some advice. I have a problem with 98 dyna wide glide, let me start from the beginning I had a petcock swapped out because I had small drip and ignition sensor pick up changed out and went from screaming eagles to Vance and home pipes bike was stored at Harley dealer ship over winter and they did the work picked it up in April took it straight home but didn’t ride it till a week later I live 10 mins from dealership the first time I took it out for a long ride 2 weeks later it stalled out start popping from exhaust island I hear like a clicking or also sounds like a shortage sound coming from throttle or from carb area some times like a clicking noise and never fails to stall out always after 20 mins to 25 mins of riding then I got to wait 15 to 20 mins to restart please help here’s what I done so far a buddy of mine told me to do I changed ignition coil , I bought a new gas cap , and rejected the carb to a 45 from 42 he said since I put Vance and Hines I had to go up on jet ?

Is it best to do it cold ? Or warm it up first ?

Go K/N Air Filter that you wash, re oil, and re use. Do the oil to the breather bypass with the catch can, stop sending that oil to your breather and engine. DK Customs offer these, or you can make your own. At least look into it. I love mine, and it's easily concealed. Only you will know, and no more mess!

I’ve got a question I hope someone can help me out with I have a 2011 Dyna street bob that does not idle right I’ve changed the spark plugs, cleaned out the throttle body, cleaned the filter and checked the throttle wires Everything seems fine but still sounds like it’s going to boggle out then the rpm’s shoot back up. Tps maybe? Thank you in advance

Run the crankcase breather to a catch can or to the ground so simple air cleaner will be clean forever

It'd be a good idea to fix your crankcase breather, it's going right into your throttle body.

That sure is a small air filter for such a big engine! Looks like it could use a bigger air box and filter like maybe a big sucker or something!

Is this a injected model

Never use compressed air on the air filter, and you clean it from the inside out, not outside in. He's only pushing the bad stuff deeper into the filter.

Oh boy…. I guess I should change mine. It’s black

Too much oil in the engine ( DOES NOT) cause blow by . Only 1 thing causes blow by >> COMPRESSION leaking by the piston rings to the inside of the engine , in other words the cylinders need bored and/or honed and new piston rings . The other thing is , when the pistons travel up and down the cylinder , on the down stroke it creates a pressure threw the engine , on the up stroke it creates a vacume >> this is normal engine ventilation for any piston engine . Harley chose to use the very low profile head breathers inside the valve covers , the breathers are not tall enough to allow enough room (not tall enough) to allow proper separation of the oil and air before it goes to the air cleaner , now add piston rings leaking to that (actual blow by)and you have a real oily air cleaner problem , its that simple . A donaldson oil bath air filter is a good example of what Im talking about , the air comes threw the oil in the bottom and up threw the tall metal mesh wire where it separates the oil from the air and then the air goes into the intake . You might be surprised how many harleys are running around with leaking cylinders and scuffed/scored cylinders , it only takes about a cheap 10.00 dollar bore scope from ebay that works with a phone and/or lap top , down threw the spark plug holes looking at the front and rear of each cylinder for scuffing/scoring . Or check the compression , anyone having EZ start cams can not check their compression . A oil build up on the Tmap sensor from the above can ruin your engine , it controls the injectors and amount of fuel (rich or lean) along with the temp sensor . Now do what ever you want , you paid for it .........
