Hello Folks,

I have an interesting question to pose here.

I have heard of several folks having primary, stator and trans issues and I am wondering if it has to do more with service intervals than with the actual components themselves.

I am initiating a poll to see how many people change all 3 holes at the same time on a regular basis vs following the moco's intervals for all 3 holes separately and if those service intervals have any affect on the components.

Definitely not scientific by any means just wondering out loud.

I can honestly say that my motor, trans and primary issues have been literally nonexistent, I do change all 3 holes each and every time I do a service.

Chime in, discuss, the beauty is there are no right or wrong answers, just a place to learn as usual.

What is your oil change frequency? 3000mi, 4000mi, 5000mi?

I always go by the MoCo Book - They built it so I'll follow their recommends

On the newer scooter, it's more or less by the book. Some times it might get done a little early, and some times a little late.

Trans and primary on the 10's

Oil at less than 5000. Usually less as the winter oil never gets close to 5000 and most summers its more than 5 and less than 10k miles.

Mobile1 or Pure oil in the motor, Shockproof in the trans, and Formula+ in the primary.

Oil at 5000 ,trans and primary at 10000 heavy shockproof in trans ,cvo oil in primary,and engine but will go with Redline in all 3holes next change

I change all 3 @ 5k. I have gone a bit over on 2 occasions. The trip to SVIV and SWVII put me over 5k.

Oil every 5k
Trans and primary every 10k

While under warranty I try to use HD Syn3... but sometimes I'm to lazy to do my service and I take to my local small shop.

Also, even though it's expensive I try to have the dealer service it once a year doing a full check on her. Usually try to average 3 services a year minimum.

Although it's good practice to check your fluid often, if my trans or primary is not clear at all, it gets changed.

Our 03' FLTRI anni is within a wk of her 14th'
Adds down to 7,500 mi/yr
Change oil/filter @3-4k primary most every x (friction material)
Trans maybe 5x, only when tinched slightly
If I let the oil go >4k seems it down a 1/2 qt
No issues before or after tensioners @ 85k

All three holes every 5000 miles including the oil filter so far (knock on wood) 57000 miles no issues

I follow the interval up here in Canadian, first was at 1000km (done by selling dealer) or so, next at 8000, 16000, and the last one at 24000 km but all three holes each time. I have also been known to drain all the oil and put fresh in when putting the bike into storage for the winter, I will do this if I am more than half way to the next change when I put the bike up. Also will make sure the gas tank is full, add seafoam or other gas preservative and resist the urge to "hear" her over the winter.

I also like to always make it a hot change, have all the fluids warmed up really well when draining them and I like to leave them to drip for a while before replacing the plugs, new o-rings on each plug each service as well.

My motto is that service parts such as o-rings and oil are cheap, regular, preventative mtce to preserve. Currently using Redline products for all 3 holes and an additional 3 ounces of "Powerup" lubricant in the motor oil.
