    It idles fine, but won't take gas.

    So much for the running 5 minutes later. It won't get gas when I choke it or throttle it but it idles fine

    Sounds a bit like water in the float bowl. Drain the carb.

3 things,

carb check
float bowl check
and clutch check.

these, if not set right will give out what you are experiencing.

you may refer to the manual on the default / recommended settings depending on the type of gas you are using.

regards, safe trails.

Okay so I have a 2003 Yamaha TTR-125 dirtbike, it is NOT electric start, it is kick-start. All of the plastics were replaced so I do not have the original stickers on it with the model, therefore I forgot...

There is a frame number stamped on the frame neck. If you call a dealer they can look up the year and model using an ID microfiche. Next to the stamped frame number there should be a riveted plate with the VIN number on it . If this plate is still on your frame it also has the model number and the model year of the motorcycle clearly printed on it. All Yamaha dealers have the ability to ID your machine using the Vehicle Identification Number.

Take to long to start.. takes almost ten minutes of kick starting... electric starter wont turn over to start bike yamaha ttr 125

The TTR-125 Carburetor's Run Lean by design. Mine had the same issues till I found a post on on Carb and air box Mod. This is a good starting point on gets; 110 and 112.5 main and 17.5 pilot. But you must check spark plug coloring to make sure the jetting is correct. Check spark plug after the bike has been ridden for a wile. I also took out the stock baffle and replaced it with exhaust tip and now it fires up after a few kicks and worms up in a few minutes.
