changing all 3 oil holes every 3k is a good thing
 

I change all 3 every 3k miles. I dont think its over kill. Its not about the oil break down and synthetics and all that but its more about getting all the contaminates out asap. Metal chips. fibers and so on. In a race bike the oils are changed out after every moto, run or race. i figure it costs 400 bucks for a dealer to do it and i do it myself for about 65 bucks so why not. Maybe its just me but after a 3 holes are changed she just seems to run better. Im not rich but im not lookin to save money on maintenance either. i save by doin my own routine maintenance. anybody else do this.

I agree completely.

I have always done it that way.

Yep
 

I change every fall which is about 3000 miles. The old oil looks dirty enough to me to say I'm glad I did that.

I follow the service manual recommendations. Oil &. Clutch adjustment every 5K, primary every 10K, Trans every. 20K. Fork oil & fuel filter every 50K.

I do the same with my 4 wheel vehicles, anything more they mfg recommended service intervals is overkill.

I have 54,000 miles on the bike, and it still runs great.

change them every week would be better. (every day would be over kill).

Change oil & filter every 2500. Other fluids and stuff is done by service manual.

In hot weather engine oil in a Harley boils. If you don't believe me pull your dip stick on a really hot day. I change my engine oil every 1500-2000 and I run royal purple synthetic oil. to me its cheap insurance.

I change engine oil and filter every 5k trans and primary every other oil change or every 10

Forks every 3rd change or every 15
Seems to make sense to me

I do oil and filter every time

Oil and filter and trans and primary

Oil and filter and forks

Only at 30 60 and 90 do all three come up together. Also I know the time I do engine oil and filter only the next time will be a larger service so gives me time to buy supplies

So makes sense to me

Way overkill. Your bike, your time, your money, but there's no reason in the world to change more often than what the manual recommends.

I'd be changing oil every 3 weeks or so during the summer if I went with that schedule.

I don't believe you. I've got UOAs that definitively prove you wrong. But I bet the Royal Purple company appreciates what you're doing.

I do all three holes every 2,500 miles with Syn3.... no issues 43k on this bike and 86k plus on past 05 Deuce. Leaving to go from NC to CA in a few days 8k in 23 to 25 days probably will not change any fluids????? hope all is OK. I am betting all will be fine.

20k in a transmission is way way to long. i dont care if its a sealed unit. Gears grind and mesh and wear. I dont care what the manual says and 10k on a clutch pack is ridiculous. Clutch plates wear big time and contaminants are washed into the oil.

5K changes all 3 on my 'King.
Mobil 1 20w50 V-Twin Syn all the way, K/N 171-C.
To each their own.

I totally agree with you. I may be a newer member on here and i get a lot of smack on here from people because of that I think, but I'm a wrench head and a plant mechanic by trade for a world renowned company. I know what I'm talking about. Oil breaks down big time in heat and I think some people forget Harleys are air cooled.

Spot on...

And yet the notoriously cheap Mothership offers a 2-year, unlimited-mileage warranty using those service intervals with non-synthetic fluids.

Though truth be told, I can't sleep if I don't change the primary fluid every 5k and the transmission every 10k. I should probably send the next batch out for testing to ease my mind, 'cause that proved beyond a shadow of a doubt that the oil is fine for 5k.

No matter what you think, someone here will disagree with it....I ignore them.

Because really....Who cares? It's just idiots on the internet!

And it's not even Winter... ;)

Also how you ride makes a difference. Of course all highway miles are easier on the oil. I do a mix of bar hoping and the longer loaded down rides. I ride hard and I spend time maintaining my machines even harder.

hahahahaha...crissake how funny, yet true! These are only opinions...I retain those I think useful and discard the rest...I never take offense.

Some change oil every 1000-3000 miles, some change every 5000-10000 miles. If you got 20000 miles on you bike and over 4 oil changes, you wasting money. The injected engines are better precised designed and can tolerate more heat and abuse. If you're getting a lot of metal and shaving when you change oil, changing oil will not stop the wear. You got an ongoing problem......

Redefining physics are we? Harley spec'ed oil has a boiling point of somewhere around 176C at sea level. If you are running that hot, you got other issues and changing the oil every 3k is not going to help at all.

Me? I try not to pretend I am smarter then the engineers designing the motors and change my own oil at their recommended levels. In the same regard if a doctor told me to take a pill three times a day, I do not take it 5 times a day thinking I am smarter. :)

Lot of hotel rooms can be had by doing such as well.

I've been know to service all 3 holes on occasion. :icon_goofygrin:

Good one.


Every 5k for all three here. Might as well do trans and primary if I'm getting dirty anyway, plus its easier to keep track that way and they are the cheap "holes".

I change my engine oil every 5,000 miles. I change the transmission and primary every other oil change. I have 63,000 miles with no problems.

Good gawd, here we go again. :icon_fryingpan:

I do the same.

.........

My last oil change at 4k my trans oil looked the same as when i poured it in 4000 miles ago... Will do it every other oil change from now on..

You mean the oil is supposed to be changed??!:icon_moped::confused:

I am fond of servicing three holes devices as well. Two hole devices are never allowed over here.

I changed to sync so that I did not have to change for 5 years or 50,000 miles which ever came first. after reading this?

I change all 3 at around 3500 to 4000. worked for me and the previous bike I owned. I'll do the same with this one too...........

I change more often if I feel bike has been run hard. Examples long run in mountains, 2 million bikers to DC, Rolling Thunder etc. When I run bike really hot or hard on trans I just plan on changing when I get home. But it may just be for my peace of mind.

I'd bet money that what you're talking about is the bubbles that show on the dip stick. They are not from the oil being boiled, it's simply air in the oil. The oil foams a bit in the bike and that's what you're seeing on the dipstick.

On another note he is an interesting read about an oil test. I'm in way saying this applies to Harleys, but nonetheless it's interesting.

You would think Harley may have learned a thing or two over the hundred+ years they've been building motorcycles, regarding oil breakdown. Their recommended fluid changes are likely spot on.

What they don't tell you is that since 2003 you should change all the bearings throughout the bike every 10k-20k miles. You know...we went cheap on cranks and bearings so now those are regular maintenance items.

Boiling oil? LMAO.

Heck no. Comparing a high strung racing 4 stroke dirt bike with a unitized engine/gearbox and a Harley is apples and oranges. A stock Harley clutch will go 100k miles with a sane owner. That's with normal recommended fluid changes at 10k. As for the transmission I've never had found any chips during oil changes only slight paste on the plug. Normal. As for the engine, any quality non-synthetic will go 5k under normal conditions. The synthetics more than that. If you're concerned about keeping the oil super clean change the filter at 3k and the oil/filter at 5k. It'll be overkill but cheaper than dumping $40 worth of good oil every 3k miles.

I don't think it is overkill at all as long as you only ride 1500 miles per year, every two years sounds about right.

Are you joking?

Still trying to get the dipstick into that third hole, but resistance happens, any advice?
