My dtr 125 2stroke will spark but only on the 1st few kicks then it will not spark the naxt few it will fire but not start thanks
You need a new cdi or a proven cdi off a donor bike , had this problem myself.
Sounds like you are flooding the engine with gas. Put in a new spark plug then twist the throttle one time to prime the cylinder. Now get your hands off the throttle and give it a few kicks. Each time you twist the throttle the power valve gives a shot of gas. Too much can flood the engine quickly.
