02 ec 250 starting problem

[ks9mm]

So things are much better now. Still not one kick bike, but not 20 kicks either. With proper tdc positioning, it will start first or second kick now, when hot.

I cleaned out all electrical contacts, put new plug in and cleaned out carb. Pilot jet and main we're both not looking good.

We also repositioned kicker bit higher.

I really hope that's the extent of the problem.


Thanks a lot for the tips!!!

Happy days. My bike wont start on the first or second kick it back fires first about third kick then starts on the button
But the ring were fooked lol

Bike can backfire on second-third kick sometimes, but fire right up with a TDC positioning.

What's the reason for backfire?

I don't know about that in a 2stroke mate never looked in to it as it has never bothered me

Make sure carb clamp is good and tight on the reed side. You could be sucking air.

im sure it is. maybe to tight

Update.

Replaced and cleaned entire pipe. Replaced airfilter. New plug with correct gap.
Had first real ride today. 30+ miles only one issue.

Will start separate thread on it.
