I was riding my rm 125 for the first time this year and it started fine i rode for about 20 minutes and i pulled over and it died. i started it up again and rode for another 10 minutes and pulled over and it died againtried to start it and all it wants to when i kick it over is backfire.

obviously theres way to much oil in the mix. Speak to your local bike shop and ask them on the best mix for the bike

SOURCE: engine back fire

Hi ...... If problem continues try switching petrol off at the tap overnight or when you stop the bike. Sounds like petrol is leaking pass the petrol tap and sitting in the bores and exhausts, soon as you start it up it's igniting in the pipes. Remove the plugs and the colour will indicate how the jetting is set up.

• If a hole in the piston then install new piston and rings. Next, clean the carbon off the head and install a new head gasket.
• If cylinder wall is scared the piston has seized up. Pull the cylinder off and take it to the dealer. Have them bore the cylinder and return it along with a new oversize piston and rings.
• While at the parts counter, get a new stock spark plug and a supply of Yamalube Two Stroke Motor Oil. You need to add 4 ounces per gallon when filling up. This will be a 32/1 gas to oil ratio. NEVER ride the bike without at least the needed 32/1 mix.

Sounds like a charging issue. First check all wires and make sure they are clean and making good contact, then check for proper voltage at the battery. I ride a harly so I don't know the exact voltage to look for but it most likly is around 13V at the battery if it isn't you need to look at your voltage regulator and stator.
