Welcome, we now have another Idaho rider!
No inherit weaknesses in the TW. Simply address good maintenance as you have mentioned and don't forget to fill up with gas.
As a preventative measure I would remove and ensure cleanliness of gas tank and carburetor and install a small inline right angle fuel filter when re-assembling. Clogged fuel passages seem to be the major source of trail side stoppages as opposed to broken chains or engine components.
The kick starter is a nice back-up to cover most electrical maladies like leaving the key on, or having a weak 1992 battery.
A better than stock front tire can help prevent crashes 100 miles from home too.
