First Mechanical Problem . . . Solved
I had my first mechanical issue with my '14 Adventure (not counting harmonic crash bar vibration, which I mitigated per advice from this forum - thanks!).
I had a sudden severe vibration from the top case (Suzuki branded Trax, purchased with bike). Upon inspection, nut to front left bolt securing metal adapter plate to factory rack decided to make a break for freedom. Solution: stop at Home Depot, procure flange nut, secure same.
Not so easy. It's impossible to place the nut under the hole with your fingers --not enough room. Revised solution: secure nut to flat side of pocket knife blade with a piece of chewing gum, slide into place under hole and thread bolt. It's possible to hold or jam the nut sufficiently with the toolkit wrench to tighten the bolt.
Just in case it happens to you!
