Hey Doc, thought I add an additional tip to the ‘wet’ filter process. While the sump is draining, remove the new o/f out of the box. Fold the box flaps into the box, reinsert the filter, seal up. The box and flaps steady/support the filter. Now fill filter to the top. Put it to the side. Caution: if your environment is dusty, place a clean shop towel over the filter - avoid contamination. Carry on with removing the old filter. By the time you are ready to install new filter, the media will have absorbed the majority of free standing fluid. This makes for a clean installation and you’re not standing around watching dirty oil drain😄.

Harley Davidson Mechanics excellent support after the sale is what convinces me to purchase Harley Davidson Motorcycles. The HD mechanics are professionals that give me confidence in ownership throughout the lifecycle of my Motorcycle.

Anybody else think Doc Harley sounds just like Vin Scully? Thank you for the video, Doc!

I used a 20oz. Pop bottle cut in half from top to bottom. Works great . minimal spill.

once again .... way to go DOC ! keep those videos coming ..... we certainly enjoy them !

Your videos help us to answer many questions. I watch every week, I'm from Brazil.

Thanks Dr Harley for making this informational video

Thanks Doc! Just purchased a Harley-Davidson Street Glide Special 2 days ago and immediately subscribed to your channel! Very informative....

Doc, yet another excellent vlog and especially about THE most important self service topic you could provide to the new and seasoned rider alike. Blessings brother!

Thanks Doc. Basic but vital information.

Another great video and tips to be noted!! ! Serve manuals are golden!!!

Always enjoy your informative videos. Keep up the good work Doc!👍😎

Thanks Doc , Big Thanks from Myrtle Beach ⛱!!

Hey Doc, I hope you're doing well, this past Friday I asked you about the primary fluid capacity and you directed me to a video you made about the primary fluid and how much to use, Thank you so much. This was my first 3-hole oil change, and I was terrified that I would do something wrong, but your videos are the best and my first experience was a success thanks to you. I can't thank you enough Doc. Now I have to go out and clean up my mess. Stay safe Doc

Thanks for all the great information!!!

Thanks for the video doc, I am one of those new Harley Davidson motorcycle owner and yes I will be doing my own oil changes after the first oil change from the dealer .

Thanks Doc always valuable information. All the best from NZ 😎

Thanks for the tips Doc!

Its easy and fun 2 do. Thx doc!

As an old aircraft mechanic is a pleasure listening to you ! Congrats !

Thanks Doc, all great tips! Btw, beautiful color on that Road King!

Great advice exactly the way ive been doing it and the only thing i never heard about is not to fill to the top i never had oil up my air filter

Love the tips. One thing I always do with my oil filters in addition to putting a little oil inside and lubing the gasket is spread a little oil on the threads as well. Makes it easier (IMO) to spin on.

Always love watching your vidoes. They are so informative. Keep up the good work Doc!! 👍

Thanks Doc... I know that you said this vid was geared towards new riders but this old dawg was taught a few new tricks!!!! I wished I could give this one more than 1 thumbs up. Thanks for ALL you do to help us old farts too... ;-)

Another great tip from the Doc! 🇨🇦

Thanks Doc. Great tips.

Doc it’s so cool that you do these videos to help the guys out here that are wrenching on their own bikes, I’ve gained tons of knowledge from your videos and really enjoyed talking to too in Rockingham

Doc, I really appreciate your videos they are packed with good content and your easy to listen to. Thanks for Sharing.

Always informative!

Aluminum foil under the oil filter works too.

Good advice for all the new riders. Teach on.

Doc I love that bike behind you the nacelle especially Thanks for all your videos mate

Good information even for experience riders!!👍

Now that was as simple as 1, 2, 3, Doc!

Thank you. Changed my oil for the first time myself. You made it a breeze.

I’ve used cut down 2L pop bottles or folds of tinfoil underneath the oil filter, to ‘minimize’ the mess. I’ve never quite figured out how to eliminate it completely, but if sure reduces cleanup time.

Awesome video…Thanks for helping us new riders out….

Good information sir. Thanks! I love your videos. 😊

Great vid doc, thanx

Thanks from South Africa 🌍

Another great video thanks doc

Good advice Doc. The cheapest way is form a piece of Aluminum foil under the oil filter like a tray. Then punch a hole in the bottom of the oil filter and then the top of it and let it run out into your drain pan. Then when you unscrew the filter you will hardly get any oil at all because it's already drained out. No muss no fuss. Then fill a new filter to the top with oil, then let it sit about 10 minutes. It will be soaked in ready to spin on. I definitely don't miss the old days of Harley oil filters in the tank that you have to disassemble the filter assembly to change like the old Shovel heads and my two Sportsters. Just my two cents worth of working on bikes for 50 years.

You are a blessing 👍🇺🇸 wish you would travel up to Myrtle beach Harley and give a seminar on anything, we all would be there. Thank you for what you do. Vietnam era/ Berlin wall vet and Dyna owner👍🇺🇸

Doc Harley is the best.

I use break life lube on the oil filter seal it’s like die electric grease it helps the oil filter come off easier syn3 gear in the trans and syn3 oil or ams oil in the engine and regular formula + in the primary

THANKS from Mississippi

Thanks for all the great info Doc, I've just purchased my first harley, a 2006 elactra glide standard, keep up the good work, Andy from devon UK.

When changing the oil filter on my 2021 Tri Glide, having hands like mine, large as a bear, I use the wrench to put the filter on. I also watch after is makes contact that I turn it no more than half turn. So far so good. Thanks Doc for all of your tips. I try to watch them all. I have been riding since my first Shovel. 70 years old now and enjoying the three wheels.

Great info Doc. Thanks

Doc your helping be better Harley owner by educating us. Thanks for do's and don't I change my own oil and you gave advice I will use moving forward. Last thing thanks for mentioning the muffler rubber Isolators...story at end of my 2700 my trip. few weeks ago I started to hear this horrible noise coming from left side toward rear of bike and took me a while to figure out it was coming from these and ordered replacement.

Doc, as usual another fact filled video. I am NOT a fan of one oil in all 3 holes. I’ve been using BelRay 85/140 oil in my transmissions, Harley primary oil in the primary and regular, Harley non synthetic, oil in the motor. I’ve never had any transmission, primary issues, or motor issues. On any of my bikes. Evo’s Twin cams, or Milwaukee 8 bikes. Your opinion, would be greatly appreciated. You are after all, the Harley guru!

Thank you Doc. 😁

Great video....your thoughts on regular vehicle oil 20w50 for engine and primary?

did my first oil change all 3 holes and was surprised. found engine oil and tran oil drain bolts were loose. I actually did not need a wrench. removed the bolts and saw they put Teflon tape on it, I tell you that tape was the only thing holding the bolts in, I had 6300 miles on it from the oil change. always had my bike serviced at Harley-Davidson, this was the first time doing it myself. glad I did it myself....Happy riding.

Great information and tips

Nice job Doc!

Thanks Doc.

Great video as usual. Thank you for sharing your talent with us.

Brilliant I wouldn't never figured this out?????????????

Hello doc harley...best oil for my 2010 harley fatboy...have watched so many of your videos.very impressed and explained so well.regards jimmy.

Great video, I myself just treated myself to my first HD for my 27th birthday!!!

I like the arrangement on my 1988 Evo FLHTC better. The oil tank drain is up high above the right rear floorboard and the oil filter is under the transmission. No mess on the front of the engine.

As always a really great video from Doc. Love all the tips. I was told to get the orange tool by a friend at the parts counter. I use it every time and it works great. Some folks might get lucky by cutting up a soda bottle. I did that at first but it still managed to leak. One thing you didn't mention, which surprised me, you didn't praise the better lubricating properties of synthetic oil. It is soooo much better. It can tolerate a lot more heat, which is a big issue with air cooled engines if you get stuck in heavy traffic. My glide now has 88,000 miles on the factory engine and it idles as quiet as a friends bike with only 15,000. I started using synthetic at the first oil change. I change oil at 5,000 faithfully. A friend changes his at 10,000 but changes the filter every 5,000. He has almost 90,000 on his engine so it must be working. The brake cleaner is good tip. I have been reluctant to use it for fear of damaging paint. I had been using Simple Green in a spray bottle. It does a great job of removing dirt and oil residue. I lay the garden hose out in the sun to get the water hot. When it's ready, I spray the bike with the simple green, wait about five months then blast it with the hot water. Any oil I slobbered on the bike comes right off. So do bugs and most grime. Then I rinse it down with distilled water from my pump up sprayer and it will be clean with no water spots.

I just shared your channel on my Facebook page for all my Harley friends to check out. This channel is too good not to have over 100,000 subscribers.

Thanks from Ukraine (Kharkiv).)

Use K&N filter with nut on end -easier to remove than oil filter wrench. I use paper plates under the filter when removing to catch oil.

Thanks for the info. That green plastic looks like a Sam splint.

Great video A++++

Thanks from the UK

For the oil filter, I use a 2 liter soda bottle cut in half. I also use a long 1/4” drill to drill through the filter, that way most of the oil will drain out before removing it. Thanks for the video.

Wow look at that bike!

Great video!

How about a vid showing you purge all the systems on a stock softail?

Another excellent video

I made a piece for the oil filter out of corragated plastic and it works perfect.

Thanks from Northern Alberta.

Sharpie makes permanent markers in silver and gold. Perfect for writing the mileage on the black oil filter.

Love your videos!

TIP: Place carboard under filter (foil lined works great) then take an old Phillips screw driver and hammer to punch a hole in the bottom face then top face of filter and let the filter drain itself empty of oil then remove. Way less mess.

I’m going to do my first service on my FXLRS and was given Harley Davidson heavy synthetic gear oil for the transmission and primary. I’ve always used the regular Harley primary and transmission fluid. What do you think of the synthetic gear oil for the M8?

Doc, …… i have question: Years ago I had a Sportster (1994) and there used to be an aftermarket round oil cooler that after you removed the oil filter you could screw on the finned oil cooler on and then the new oil filter behind it. It also gave your Sportster slightly more oil capacity along with extra cooling during very hot climates. During the winter time there was a leather sleeve that slid over the cooler to block the now much colder air flow on the fins but still allowed for a tad larger oil capacity w/o having to remove the cooler. I wanna say HD used to sell this product but have not seen one in 26 years. Any ideas on who made these animals and where/how I can get one now for my bike ?

Here's a cool trick for checking the crankcase breathers while doing an oil change - leave the oil filler cap on when you first pull the drain plug. The oil should drain quite slowly. Now remove the oil filler cap; the oil should drain a lot faster. If it does you know your breathers are working as they should.

Thx Doc

Take it to the shop, write the check!

I use an old skillet to catch the oil works pretty well. I have to laugh at myself when he talked about getting the bike hot before changing the oil, let's just say I didn't let my bike get hot enough, I change the oil and one day while riding the back pressure in the crank case popped my dipstick out of the tank I had oil all over the side of my bike. At least now I have the proper amount of oil and it's not over filled, so yeah if the oil isn't hot enough not all of the oil drains out.

Have a 2020 XL1200NS, bought new last summer. I'd like to change all the fluids this spring as all of the fluids are 2 years old. Going syn3 for the engine. What do you recommend for the transmission/ primary? I want to run the best, regardless of cost. Considering syn3, formula plus and the screamin eagle synthetic gear oil.

Cat litter tray makes a good oil catch container.

Nice video doc! I'm getting ready to change my oil for the first time. *Here's a topic for a new video: SPARK PLUG WIRES!* I've read so many conflicting things about spark plug wires. I think some manuals say to replace them every three years, some people say to never replace them and they never wear out. Some say to replace the bad ol stock wires with some better ones as soon as you buy the bike. Some say to test them with an ohm meter, some say to put your tongue on the wire while its running, if you get shocked then you need to replace them LOL. I just ordered some Accel 8 mm plug wires, it says they deliver five times more energy than stock. Some wires claim a significant increase in horsepower. Some are thicker wires, does it matter if you go above 8 mm? I think the thick ones look funny LOL. I just replaced my starter, battery and spark plugs, my bike starts better than almost any Dyna I've seen. Going to do the wires because my bike is 14 years old and I'm pretty sure those wires are stock. It would be nice to hear your input on spark plug wires in a video!

on a trike, there is no Jeffy so I guess it's safe to change all fluids while 3 wheels are making contact and level on the floor. thank you for all you do love your channel. any tips for m8. fluid change ?

Never knew i needed something to catch the oil, always thought that was for the ground to do.

So Doc have you ever had a idle air controller go bad? I have been having a problem with the 2018 Road Glide idle, am talking bike in a couple of day and my mechanic says that they've not seen this problem.

The bigger problem is Teflon tape on the end of the plug is cutoff and is now in the engine oil system. It can plug small holes and can keep seals from working. If you use Teflon tape, use only two raps and leave the first two threads exposed.

Great tips , thanks for sharing the knowledge. The service manual doesnt talk about a full purge oil change ,what are your toughts on it,.

Hey doc thanks for your vids mate Good to see some real good advice I've been using hylomar blue the last 20 years If I'm in doubt about thread seal tape I use this If you haven't tried it certainly recommend it Be safe mate these days are strange And good to see something normal like you

And if you fill to the full mark you will get more oil blow by in your air filter/throttle body. Unless you have a external breather.

That magnet!

Love the videos. I just bought a 95 wide glide s&s motor...would like to know how to tell if it's a s&s evo

Hi Doc, my question is: On a 2015 HD Dyna street bob 103TC can I use 3 different brands of oil for (motor, tranny and primary)? Or should I stick with same brand for (motor and tranny for ex. Amsoil) and a separate for the primary for ex. red line)? Thank you very much

Doc,. Dork medical problems, I had to trade in my Ultra Classic for a Tri-glide ultra. I know the motors are the same to wrench on. Would discuss about the back end of theTri-glides..
