Inner Primary Warped?
I was wondering if anyone has heard of this? My 2007 RK had a small leak. The dealership replaced the inner and out primary and returned the bike to me. I discovered that the problem was still happening and the leak was with the jackshaft seal. The dealership fixed that problem and the leak was down to a drop. I brought it to the dealer and now they are saying that the heat warped the inner primary which was chrome plated. They are claiming that chrome plating causes things to warp "after a while." The part is about 5-6 years old. Has anyone heard of this before?

In a word...... NO
If it cracked or something like that who knows but warped? maybe they dropped it and damaged the sealing surface..... Who knows..... Find a more reputable dealer

Got a chrome one on my 04. Been on there since 06, off and on half a dozen times due to various issues as I have 170k on the clock.
No leaks, never had a problem. sounds like BS to me

I would be blaming a crappy gasket, torque specs, etc before chrome plating.

you can check for a warped case by laying on a sheet of plate glass ( Like the coffee table)...poke at the edges with a feeler gauge.
an improperly torqued case can warp- as can a crap casting- case warping is rare for the twin cam era Harleys. aftermarket who knows- that's a crap shoot.
the twin cam gasket which superceded the old paper gasket does not seal as well on questionable ( or evo) cases
the old evo paper style gasket is for sale across the street at the indy shop, go get one.
that'll seal the edges

And the Saga continues
OK.. so the word the word this morning was that they put different colored fluids in and the leak is from the inner primary. It only leaks when its hot. Which further makes no sense. If the part is warped why would it hold fluid when it is cold. I may be missing something. They are going to take it all a part again and try to redo all the seals. We have used this dealer for years and years. Thanks for all the information I will be passing it along before I buy a new inner primary.
