If you are going to fiddle with jetting, you may REALLY want to set up a record keeping sheet so you know where you have been already and don't try the same thing two or three times. It is easy to forget what you did and actually, what jets you have in right now. If they are a good set, fitting your conditions, you are more likely to remember, but will have the occasional "I forget" moment. If you put it on paper, how it worked, impressions of performance, rough weather(rain/dry, cold/hot depending) for a given jet, it will give you some information as to which 'way to go' on the next go round.

My first bike was an SG250 last year, the best advice I can give you is leave it alone! Leave it as stock and ride it and enjoy it. To much fiddling with it and you will inevitably break something trust me.

In theory, the K&N and the pod are less restrictive to airflow. That is good and it is bad. Good for more power, more fuel usage per mile, but bad in that they reduce restriction by being less effective filters. They will pass more particulates. The problem of over or under-oiling the media is also very common. Too much and you restrict airflow, too little and you let too much dirt into the engine. Question becomes is it worth the aggravation and possible damage from dirt particles? Your choice.
The increase in airflow may require a larger jet. It depends on your location and altitude you ride at. You may want to do your thing with the filter of choice, and install a new spark plug at the same time. Ride for a bit, doing normal things, and then pull the plug and examine it for color and deposits. A lean engine will generally leave the plug very clean. A normal will leave slight deposits, likely tan in color. An over rich engine will leave black sooty deposits. tom
