First, most of those small bikes do not have a fuel filter. Refilling from odds and ends gas cans often means sediment and crap in the gas. Consider a fuel filter.
Tires: Try to figure lout what you want to do with that bike. Dirt tires do okay on pavement, but pavement tires do NOT do okay on dirt Various 50/50 tires or something similar may be in order.
Storage: Saddle bags or panniers are great. A must have in my book. Panniers are better. Do not buy side opening cases since everything falls out. Buy top opening. You may want to look around. Hard cases easily run $800++, with many options starting at $1000. Some creativity, two 20mm ammo cans and some paint could get you a long way. Remember, its still a 230..... It's not going to do well with 200 lbs of rider and gear, and a 100 lb of luggage.
My bike has a top case, but its not a motorcycle specific case. Previous owner mounted a Lowe pelican-type case and it works great. Consider somesort of small loop or other attachment points so you can bunge a large but light item to the top (think sleeping bag or similar).
Lights: I don't know what the alternator on that will generate. I suspect its not much. Plugging in lots of lights will likely tax your electric system. Look at a pair or high end LED aux lamps. I bought Denali's, and these are 10W if I remember. I set them up on the forks, and they are wired to my high/low beam. t low they push 40%, and when I turn the highs on, the denali's go to 100%. I love them. Krista's are great too. These are all not cheap ($300+) but are worth every penny. They serve as daytime "please see me" conspicuity lights and as auxiliary lights that widen and fill in the night time headlight pattern. Really helpful.
