Maintenance & Technical > KX250 / KX125
01 Kx 250 need help no spark
NLburden:
Also changed out the igniter ( black box connector under the seat ) with a spare one however no spark either
Foxx4Beaver:
how about the regulator behind the forks on the frame neck...have you swapped that yet?
or have you tried swapping the coil too?
another thing, that's rare, but not uncommon...is the magneto goes bad....you can try swapping that too if you have access to a spare.

While to Red 7-15 Ohms
Yellow/While to Yellow 1-5 Ohms
It would also do you good to buy a Clymer or similar service manual.
Do not buy a owners manual..

Just did this with my multimeter again with both stators on the bench. Using the connector end only I checked both red- white and then yellow - white/yellow.
One Stator #1 ( old stator ) Results:
White to Red 11.2 Ohms ( and yes continuity of course )
Yellow white to yellow 0. No continuity. Wouldn't beep. I messed around with it to ensure i had the meter fully inserted.
Stator #2 ( was brand new with a few hours of use before bike died )
White to red 0 .. no continuity.
Yellow / white to yellow 0... no continuity.
I think we have our culprit. What would cause a brand new stator to have this happen with only a few hours of riding since a brand new engine build.. Bike still is not running just wanted to post this online to see what your opinions are before i go and buy another part to throw at the bike haha

no brand new part is guaranteed not to fail in a short period of time....especially electrical/ignition parts...that's why you don't get a warranty on them.
you may very well have just gotten a "lemon".

So i Retested just then to make sure I did it right. Realized I did it partially right haha. It says to test Yellow/white to yellow.. I was checking yellow/white to white.
Old Stator ( #1 )
Pins Yellow/white to white = 2.3 Ohms
Pins White to Red = 11.2 ohms
Checked for shorts as well, no shorts. Appears to be working.
New stator ( Stator # 2 )
Pins yellow/white to white = 2.3 ohms
Pins white to red = no connection / no continuity.
I had a friend over to the house yesterday and we tried cranking the bike with the old and the new stator. Even with the old stator installed ( which i've just learned tested out fine ) still didn't produce a spark. I will try what you mentioned earlier and try swapping the ignition coil again
