Probably a clogged carburetor. Take out the air filter and Squirt some carb cleaner or contact cleaner down the intake. Try to start it. If it starts, then dies quickly then you have a fuel delivery problem(dirty card, clogged petcock)

Hi, Anonymous and the usual suspects are:
1. Fouled spark plugs.
2. Severely discharged or a damaged battery, should have 12.5 volts or better and be able to pass a load test if necessary.
3. Check battery terminals for damage or corrosion, check the battery cables at "BOTH" ends for loose, corroded, or broken connectors, "INSIDE" and outside the cable harness, perform connector wiggle test and check cables with an ohmmeter if necessary.
4. Loose connection at ignition coil or plug between ignition sensor and CDI box.
5. Spark plug cables in bad condition, shorting / leaking, spark plug cable connections loose, check for spark leakage in the dark.
6. Faulty ignition coil, pick up coil, trigger coil or CDI box testing needs to be checked with an ohmmeter at 70 degrees Fahrenheit
7. Faulty safety switches clutch, kickstand, neutral, off/on etc.
8. Faulty ignition switch.

Yam ybr125 wont idle off choke,also cannot find idle control scre


you may need to replace your spark plugs

as the idle should remain constant as long as the tune of the bike is good IE oil changes done regularly / plugs cleaned and or gapped , air filter cleaned or replaced all of these can affect your bike.

hope this helps
