idle adjustment or carburetor?

I've been trying to Google my problem for about a week now... I need some help!

I have a Kawasaki 2010 250r, I purchased it brand new in March of 2010, I take it to get serviced regularly and I have never wrecked it to cause any frame damage, only cosmetic scratches on both sides.

In December of 2011 I let it sit for about a month and half, I had to get a major tune up for it and but ever since then every morning when I go to start bike, I have to not only open the choke completely on my bike to get it started but also adjust my idle really high.

Is this normal? How can I tell if I have a problem with my idle adjustment or carburetor? Is it something else?
If anyone has any suggestions or ideas I would really appreciate the help.

crappy gas + sitting idle = dirty carbs
Seafoam may may help, could be as bad as a carb rebuild. Keep us posted on how the seafoam works. There are a couple of other tricks to try.

If the carbs are anything like the older model carbs, there is an adjustment needle for the idle mixture that is capped off from the factory. A little tuning of that needle did the trick for my old 250. My symptoms were inconsistent idle (hot or cold). After minor tuning the choke was unnecessary and had a much better/smoother idle.

What's your idle set at? I find that the 250s like the idle to be sitting at 1500 rpm. Set your idle when your bike is fully warmed up and the choke off. Make sure your vacuum hoses aren't dry rotted. That can cause idling issues.

How many miles are on the bike? If you're over 7500 miles, than your bike is due for a valve adjustment. You'll find that the exhaust valves go on the tight side and out of spec and can give you problems with hard starts.

So how long have you ridden the bike since dec 2011? Has it always been giving you issues since then still? If you don't ride it much, than I'd say that carbs are dirty still. Run some seafoam and see if that changes like suggested.

So much awesome...

Wow! You guys are awesome! Honestly I wasn't expecting so many replies/suggestions.

Where to start? ...

The bike has 19,200 miles on it. I have no idea what I am looking at each time I decide to open it up to look inside, that's why I take it to get the oil changed at Motorcycles Unlimited because I know they check stuff that's important like damage to cables, parts, etc. if there is any damage.

I was told once that I had a lot of debris in the gas tank. I always fuel up with supreme and I always pump gas at places like Shell or Exxon vs rinky corner gas stations because I would assume that Shell and Exxon keep thier gas cleaner? Anyway I don't think the gas is the reason my tank had debirs. The reason for the debris might be that there is a hole in my undertail from the rear tire hitting the undertail plastic. Reason for the hole in the undertail: When I purchased it in 2010 I had it lowered 2 inches, because I'm only 5' tall, before I ever drove it off the lot. I didn't have them adjust the suspension because I ride solo and didn't think it would matter. Well, my friend decided he was gonna give his girlfriend a ride on my lowered bike and their weight made a hole :/

Just from reading your replies my first instinct is to try the Sea Foam, although, I have no idea what that is or how it works so I'll have to Google that.

The bike is basically my main source of reliable transportation so I would have to say that since the major tune up in December 2011 I've been riding it err day. Haha. Rain or shine, Ride or Die. Right? Hahah.

Diana,
You can pick up Seafoam at Walmart. The instructions are on the can for mixing it.
The debris that was in your tank is not from the hole in your fender but from some bad fuel you had picked up.
If you get a chance, swing by and I'll check the idle for you.
