Not unless you have the time and a little bit of experience and the proper tools, there are some things like valve adjustments, that you might want to get a little help from someone who has done it before. Oil changes are fairly easy. There are dozens of DIY videos on Ninja 250 oil and filter changes.
As far as the smoothness of the bike goes it could be a combination of things. (old fuel, dirty air filter, dirty carbs, improper idle speed, operator inexperience)
If you only plan to ride the bike once a month or so, just make sure you keep the bike in good running condition so when you are ready to ride there won't be any problems. Following some Winter Storage Tips
