Meddling with carburettor

Last few days of mine were lost into digging information about Fuel Injection and Carburettor and thankfully with help of some of my friends and netsphere I was able to get a good dose of knowledge.
P200 being a carburetted one I concentrated on carb mostly.As you might be knowing, carb plays a vital role in welfare of your bike's health.A detuned carb can greatly reduce the performance and efficiency.While a neatly adjusted carb can do wonders.
The fact also helps that carbs are much easy to tune/alter than FI.It doesn't need all that electronic gadgetry which FI needs. Once you get to know the basic hardware of carb its easy to do a makeshift operation on it in case anything goes wrong.
In my case the fuel efficiency had gone awry and engine was jerky in 1st and 2nd gear.When I enquired with some, it turned out that carb was set for too rich mixture(which meant it was forcing more than necessary fuel into engine).
Locating the volume control screw is easy.In fact its the only screw on LHS of carb other than the one for setting idle.Besides its bronze color so no mistaking!









As from the pic, I don't need to say the obvious, But will say it nevertheless!
Turning right the carb will channel less fuel and more air making it lean while turning it left will channel more fuel and less air(as in my case).
So adjust it accordingly.
However don't go overboard on either side. Maintaining it on a perfect position is best and will give you right amount of performance coupled with efficiency.
(Remember one thing turning it completely towards right or left doesn't mean peak efficiency or performance respectively) For engine's health you must maintain the balance.
There is one cliche though. Before you embark onto this learn to read your spark-plugs.Don't panic!!Its easy and a must know for enthusiast biker.
Remove both the sparks and check their electrodes for color.
If its more on the brownish side your bike is running on leaner mix if its way too much black your bike is running on rich mix. So ideally it should be dark-brown(almost black but not black!).
When you adjust the volume control ride the bike for a few kilometres and then check for color of the spark plugs tune it accordingly until your bike is running on balanced mix.
One more precaution to take- Don't turn the volume control like you do with normal screws.Do it slowly and only by half or a quarter turn at a time.Its much sensitive.
