Hi I have a TTR 125 jetted to 17.5 pilot and 110 main and is still hard to start. (I know the main has nothing to do with starting but I threw it in there anyway). Today I wore a fully charged battery all the way down but still no cigar. It may crank up for 2 or 3 seconds the die. My fuel screw is set to 2 turns out. It takes me 20 minutes to get the thing running. I have cleaned it at least 10 times. Once cranked and "warmed up" it runs fine. I live in NC. All help is appreciated.

If you have a 17.5 2 turns out I would suspect it is flooding the motor.
Is the plug wet after trying to start it for a few minutes?

Top secret starting technique-
Pull out choke, crank for 5 seconds, turn off, and walk away. Fuel is starting to be pulled up the choke supply tube.
Try again in 5 minutes, and it may fire right up. Leave the choke in the pulled up position the entire time that you are letting it sit. It seems to use vacuum from the initial start to get fuel flowing.
If it won't start, and it is above 45 degrees or so, it still has a plugged passage somewhere.
