I just wanted to address a few issues regarding chrome bolts.
The situation that brought this on was caused by a thread hole that had a build up of factory thread lock. I have seen it myself when I did my first install of the 09 Touring. I didn’t chase the thread but did feel the extra resistance, especially towards the end because of the excess thread lock accumulating on the bolt.
You can take any bolt and thread it into a tight hole, but if you are threading it quickly and have a significant amount of resistance that bolt will snap. Combining the heat (caused by friction) and enough torque this will happen, we have all done it. It didn’t mean that something was wrong with the bolt, it meant that it was installed incorrectly.
As for my fasteners. I use chrome plated grade 8 bolts because they provide the best protection from corrosion and they’re aesthetically pleasing (grade 9 is not recommended).
I have done environment testing on Chrome, CAD, Black Zinc and the Socket Cap standard finish (Black Oxide). I found (and it is well known) that the least amount of corrosion protection is with Black Oxide (black bolts).
Even the threaded area is subject to corrosion on black oxide bolts. This is why they are not used on the BLACKED OUT bikes that come from the factory. They use Black Zinc and this is why when a customer of mine says they need black hardware I send black zinc and not off the shelf grade 8. I even black zinc my lock washers.
I would recommend to anyone who is working on their own motorcycle to:
- Take the time to clean each bolt before installing and use a 243 blue loctite when applicable (242 is not oil resistant).
- NEVER force a bolt when threading. If you have to force a bolt then take the time to figure out what’s wrong.
- Never use Stainless to Stainless, Aluminum to Aluminum or Chrome to Chrome without using an Anti-seize first and also know that Loctite actually does have anti-seize properties.
I do have pictures of what a black oxide bolt looks like when mounted on the underside of a bike and when left out with full exposure. For the mounted bolt, with no water exposure there are some signs of corrosion after about 10 months. The one that was left outside (full exposure) with the morning dew and afternoon sun showed corrosion after just a few weeks. I’m not saying that using a black oxide bolt is the worse thing you can do but I am saying that there is a reason for what we do and that reason is to provide the very best product and value that we can offer.
FYI, out of the over 3000 kits that we have sold we have never had a bolt break while in use. You are talking about 4 grade 8 bolts holding the weight of one person. We did have one bend in a collision though.
You guys might also be interest to know that upon request we do offer CAD PLATED or BLACK ZINC PLATED bolts at no extra charge. Just include this in your notes when ordering.
Here is an interesting Tech Tip on motorcycle fasteners… http://www.raskcycle.com/techtip/webdoc14.html
As for CASS - we have had several email conversations regarding this (at every step). He is being taken care of, mostly because this guy really had a bad day over this. As for details, I think that is something that he should share.
Thanks for listening guys,
