Loads of fun... The center stand is a pain if it is too long. It forces you to lift the bike and as you know there is nowhere to lift from. I measured the tire height off the ground, and cut off 1/4" less than that number from the legs. This lets the bike mostly roll up onto the stand with much less effort. If you decide later to get a bigger tire the stands are cheap, and easily replaced.
I love Vivo, and his advice is always more sensible than mine but DON'T wait for the light. If the float/wiring/bulb go out then so does the engine. Then you will be pissed off that the bike didn't tell you when to add oil. Depending on how you ride the bikes Avg. about 2 oz. of oil to a gallon. You can do the math there. I always use Premium fuel. No exception. Same for 2stroke oil. Synthetic blends are great, and Full Synth. is awesome. Stay away from chainsaw, and weed wacker oils. They are junk, and will foul out your engine in short order. The only oil it gets is mixed in the fuel. You need good oil.
Aftermarket parts abound for the 2t Kymcos. You can spend 3-400.00 and have a mildly tuned bike that does 50-55mph for years. The best place to start is with an exhaust/carb jets. Then you can move up w/ a variator, and a clutch. They even have rear gear sets for these so 60mph is reachable w/ the stock cylinder bore.
Spend some quality time on the forum,(tell the Mrs. you're doing it for her) and read some of the MOD threads or most any of the 50cc threads. You'll find we are mostly a bunch of Jacka_ _es with too much time, and lots of money to waste but everything you could ever do to a 50cc has been done here. (No-one has done a turbo yet... hint
) but it's all here.
Post up before you buy something. We have also weeded thru the crap parts houses, and can save you alot of time, and $$$.
