have you checked the valve gap if the valves are open this will cause low compresion if not there may be a crack in the head or cylinder but not to clever with bikes sorry

Drain the tank and switch to a 32 /1 mix. I take it you have disconnected the oil feed to the carb from the 2 stroke tank, if not then your mix contains too much oil. Only switch to 32 / 1 if the oil tank has been disconnected. I hope this helps.

Check the air adjustment lever. When u start the engine set the air adjustment lever high. When your engine get warm turn the air adjustment lever low. Please try it.

2 stroke engine oil for the engine goes in the oil tank under the seat.
motorcycle gear box oil goes in the gearbox, car oil may cause the clutch to slip.

Yamaha DT 125 X... | Answered on Apr 11, 2011


I would say the ignition switch wiring is incorrect. The first possition should feed horn, brake light and ignition and position two will run the lights. So find the wire that feeds the horn and brakes then remove it from position two and connect it to position one leaving the lights on position two.
Hope that helps..

cover up the drilled holes this can cause problems, why was a new carb fitted? did the shop have it running?
not likely rings .
check carb for flooding and correct jet sizes.
check safety kill\start\run switch for shorts.

Yamaha DT 125 X... | Answered on Feb 25, 2011


It sounds like it has seized up. Hopefully just the piston rings but you will have to take the engine apart to check.
Good luck.
