Bolt Corrosion
Hi All, I have an issue with a bike I recently purchased. It is a FXSTB.
Most if not all of the bolts on the motor have a white type of corrosion thing going on. They look calcified if you know what I mean. The guy said it was never in the rain but maybe it was left over from washing? Does Harley or Aftermarket make a corrosion resistant bolt kit? I have seen the caps you can get for the bolts to dress it up but I am thinking that will just mask an actual issue and I would rather just put better corrosion resistant bolts in. Can I just pull these bolts, run them under a buffing wheel and reinstall? What could be causing the corrosion if indeed it was not in the rain?

Same story here - just purchased 2007 Fatboy with 3600 miles on it. The nice 56 yr old swears it has been always kept in the garage and never driven near the ocean. Nearly every zinc bolt and some of the chrome bolts are corroded or rusted. They must have really cut down on the quality of the fasteners. Cheers, Kevin.

Will start looking myself - first stop:

Not very descriptive - have to look at bike to see which bolts these are; get the feeling this will be a long process - that's OK, it's almost Winter here in S.FL. My theory is everybody stays indoors for 3 months; the difference is we get to use the pool Cheers, Kevin.

It has nothing to do with moisture. It's a form of galvanic corrosion caused by the fact that your entire bike is a conductor to get all your electrical connections back to ground. Find the ground strap on your motor and you'll see that it's all part of the electrical circuit. The corrosion is due to the voltage that has been passing through the metals for a period of time. Some metals are more prone to corrosion than others, while others are totally immune to it.

Ahh - lightbulb - duh - feeling stupid now :-). Lived on a sailboat for 13 years, but never put 2 & 2 together to realize it as also galvanic corrosion between dissimilar metals on the bike. Kind of makes me wonder why they dont put a sacrificial zinc on the bike. I love learning new stuff after a a great morning breakfast ride - sweet :-)
