Is it normal for a 2012 FLHX (SG) to have rusted derby cover bolts and holes? All work on this bike has been done on by HD.

What would cause this. The bolts are also rusted.

 

Where’s the bolts?

 

That is typical of not using anti seeze or locktite on those bolts. Most use a tiny bit of antiseeze, as locktite isn't really needed in that location. But locktite will prevent the galvanic corosion from disimilar metals like that just as well as anti seeze.

 

WD40 on a q tip...….

 

So you did a poll? How do you come up with the equation about most people use anti seize?
I would guess most people just reinstall, but that's purely a guess.

 

No sir I did not, but I did pay attention to what I read here on the forum, as well as to all the bikes that i have worked on. And in my estimation based off of real life experience and what I have seen in answers on here, more folks use antiseeze, than those that do not.

 

replace with stainless steel.

 

And if you do use stainless fasteners, be sure to use some type of lubricant on the threads.

 

Yes definately lubricate it then, as this will cause galvanic corrision even faster in the area if not protected.

 

The issue with stainless steel is not corrosion, it is galling.
