Where did my chain adjuster/swingarm cap go?
If you don’t thoroughly counter-tighten the nuts on the swingarm caps, they can work themselves off, and you will lose the cap. If the axle is tight, this is not an immediate problem, and can be temporarily fixed with fender washers. To avoid this problem, repace both nuts with a single M8 nylon insert locknut. Note that these are generally 13mm hex, which is not included in the stock tool kit; you’ll have to pack something.
