+1 on not using Canyon Dancers on the cast aluminum bars of the FJR, (they can break), and on removing the windscreen for trailering. You'll
probably be ok if you leave the windscreen on, but why risk it when it's so easy to remove. And not tarp-ing the bike directly.
FWIW, OR doesn't use salt, though the de-icer can cause some corrosion if not rinsed off, over time. BTDT on the exhaust cans of the '04 FJR. It takes a while though. I noticed it when I gave the bike it's annual wash in June...
@Hello Kitty - Girl, why am I not surprised that you choose to purchase the tape measure with the longest "stand out" in production? It's not so bad now, but when you were single and you carried that big ass tape measure on your hip in the bars, it would just make men walk away from you honey.
And the drunks would insist you start measuring like you would on a cat's tail...
Do consider renting an enclosed trailer, BUT do not tell them you are putting a motorcycle in it when you rent it. They will insist that's not ok. And it will be a pain in the butt from there on out and cost more money than you want to spend.
An enterprising fellow could build a wood frame around the bike, and tarp that tightly, so the tarp was not against the bike. Just depends on how much trailer you have and how much energy you have.
Generally, I'm with Iggy. I've ridden in way too much rain to ever worry about what a little water would do to the bike. But if you stress about it, there are options.
I used to say there were no stupid questions, but there are...
However, for every question someone asks, there
are about a dozen others that were thinking of asking it. So all questions do benefit in some way.
