Get it clean
There’s nothing like a tank/bodywork-off spring clean to restore your bike's karma. Use a good bike cleaner spray, work it in with a paint brush for stubborn muck and hose (or better still) jet wash it off for a nice, cack-free bike.
Only when a bike is clean can you spot errant or loose fasteners, dodgy wiring or parts that foul one another.
If you’ve gone far enough to take all the bodywork off, this might be a good time to do your own basic servicing but before you do get the bike as dry as possible first. An air line and air gun is the best way to do this but failing that, a small, absorbent dog will do.
