I'm still on the original primary gasket on my 2002 and it's been on and off too many times to count. I believe the shop guy claims he changes them out every 5k but I don't believe they really do. Heck, with a newer bike, unless it's making a racket from the comp or the chain, there's no reason to go in there every 5k.
To answer your question, no, I have never heard of a dealer changing that gasket every 5K. If I took my bike in for the different 5K services and they charged me for replacing the primary cover gasket, I would be pissed.

I told him I never heard of that gasket being changed. He told me the original was all paper and the upgraded was a MLS. Thats what I bought.
I'm looking forward to checking the Chain tensioner for piece of mind since momma wants to do (me on) a road trip.......

Hmm, the OEM part number is 34901-07, so unless he's selling you an aftermarket gasket, that OEM gasket hasn't changed. I call bulls*t on your parts guy.
BS - I have several TC's that have went 30 to 40 thousand miles without ever needing a primary gasket even when I installed SE clutch springs and reused the original.
I have never replaced any o ring derby cover gasket ever. Don't have any with the paper one. It has been a long time since H-D used the paper derby gasket. More than 12 years.
Traildog should you decide to pull the outer primary cover I'll give you a tip I use. I have several old long primary bolts with the heads cut off and the ends cleaned up (not the part that threads in). I screw them in by hand on the inner primary in a couple different places before I re-install the gasket. I hang the gasket on the locating dowels and the headless bolts. It makes putting the outer cover on easier without having the gasket fall out of place. Once I get a couple of the regular primary bolts in, I remove the longer ones by hand and replace them with the rest of the bolts. I torque everything down in sequence and am good to go.

My RK drops one and only one drop of oil over night. I mentioned it when I stopped to get new O rings for my 10K service and the parts guy says their shop changes the outer primary gasket every 5K.
Anyone else ever heard of this? I was planning on changing the gasket anyway but I've never heard of every 5K.
I USED TO change the primary gasket whenever I changed the primary oil, which by the way is supposed to be every 10,000 miles not 5,000 as stated in your owners manual. But like all fluids I change sooner, just because I enjoy too.
I only change the gasket after every two to three changes once I read others do it that way. I found out they are correct, no need to change the gasket every time.
I am surprised you have oil leak. I never, ever, ever even have a drop of oil leak onto my garage floor. If its coming from your primary cover then maybe whoever is changing the primary oil is not properly securing the cover on. The bolts should be properly torqued and secured in the manner outlined in the manual, there is a reason for this, its so you dont warp the derby cover to where it doesnt sit perfectly flat which would then allow a small amount of oil to leak.
