I own a '04 Yamaha TT-R 125LE. I bought it brand new from a dealer brand new last year around Christmas time. (Never sold at one their other stores that is shutting down) anyway, when the engine is at normal operating temp. it idles really slow and crappy and then it dies. How do I adjust the idle speed or what is wrong? I am wondering if adjusting the idle speed doesn't work if the bike is vaporizing the gas to fast or if it's flooding itself? I took a closer look at the carb today and when the bike is just idling or sitting (not running) and the gas is is turned to "on" the gas just pours out of the overflow tube on the carb bowl. What's wrong?

--Overflow - clean the carb. There's probably a little spec of dirt in the float needle and not turning off the fuel to the float bowl.
---The idel screw is on the left side of the carb (the screw has a coiled spring on it). Turn it clockwise to increase the idle. Adjust the idel when the engine is warmed up.

OK...you should have a 'choke' on the bike, if you don't know what that is then go to a dealer and ask or go online and find a picture, with the choke you should, as for the leak of the gas turning the idle speed should keep it from doing that, having it idle faster will make it eat more gas which stops the leaking so ether way your gonna lose that gas. let it idle for about 3-5 minutes and it will ride great.

if the carb has a bowl and float, the float could be sticking. if it's a CV carb check the diaphragm.
another idea - perhaps there is rust in the tank. if the bike has been sitting around for three years the tank may need rinsing out (with petrol), old petrol can get a bit jellified

The needle valve on your float is not closing the flow of gas at the proper level. It could have dirt on it or the needle or it's seat is damaged. Clean the carb and change the needle valve and seat.
Make sure you adjust the float after changing the needle valve, follow the instructions in your manual to do this properly, It's that hard to do yourself.
