I just traded a 2003 Ultra Classic for a 2011 CVO Ultra Classic Electra Glide with 4k miles. Going to change all fluids soon. I did not get a owner's manual with purchase of the bike. I ordered one online and have received it yesterday. My service manual is on the way. I do my own fluid changes. The 2003 Ultra all fluids were changed every 5k miles. In the 2011 owner's manual states oil changed every 5k, primary chain every 10k, and transmission fluid every 20k. I use Lucas syn. 20-50w for oil and primary, and redline for the transmission. I was shocked at the difference in fluid change intervals. Do most owner's do the 5k oil, 10k primary, 20k transmission fluid changes? Thank you for input.

I have followed that schedule as you stated. Never ever had any problems with primary or tranny.  Plenty of problems with the 110 motor but not related to oil change intervals as far as I can tell. Many lifter and cam bearing failures even to those who follow a shorter change interval.

Hi maugusta1, I think a number of members would tell you that as long as they're changing fluids that they change all of them. That's what my dealer does when I bring the bike in for service and what I do when I perform the service..

I moved your thread because it's more of a technical question than an introduction. Please feel free to start another introductory thread and tell us about yourself.

Welcome to the forum maugusta1,  There's been a lot of guys on here with oil questions including myself.
Each have their own preference and suggestions along with what oil each individual uses and oil change schedules.
If you have a read upon some of the postings you'll get a good idea on which maintenance is good for you.
For myself I use a Motule 4T 7100 20W50  100% synthetic for all 3 holes, but i change the motor at 10k the primary at 5k and the transmission I will be changing over to a transmission gear lube that will be on a 25k schedule.
The reason the primary gets it at 5k is do to the clutch powder contamination to the oil.
What ever way you go at the end of the day you can't go wrong with 5k changes.

My personal recommendation, for those who just wish to have a basic schedule versus doing oil analysis to determine when the fluids actually NEED to be changed, is to stick with the 5000 mile interval for both the engine and primary.  The trans can go 20k easily, since it isn't exposed to the kinds of contamination found in engine oil.  How often did you change the rear axle or manual transmission oil in the last car or truck you owned with those features?  The reason I say 5k versus 10k for the primary has to do with the large amount of metal and clutch particles found in late model primaries.  When you do your first primary oil change you will see what I'm talking about.

All holes at 5k and like Jerry said the tranny can go a lot more than that, but for changing one quart I'm not getting out the jack again.

Used to do 5k on engine, 10k on primary, and 10k on tranny.  After observing what Jerry refers to here, switched to 5k on the primary.  Primary change is the dirtiest fluid usually, even at 5k.

Thank you  GENTLEMEN   for the input.  I did not understand how Harley all of a sudden increased their fluid change intervals. I felt 10k for primary and 20k for transmission was a large increase from the what I felt was a normal 5k total fluid changes. I respect everyone's choice with what fluids they use. It shows to me that everyone agrees to regular fluid changes no matter the name or brand of the product of their choice. Found the CVO forum after my purchase of the bike and love reading all the posts. Everyone keep up the good work.............Ride On

I agree.  I've always done the primary along with the engine oil.  did the clutch adjustment first, then warmed the bike up and did the fluid changes.  always felt like a new bike when done.  course with the hydraulic clutch, the clutch adjustment portion is moot now, but still follow the same schedule.
