Kawasaki kmx 125 electronic problem

[HardDriver]

Hi to all again. Long time no post it here, but I came with problem. My bike broke up.

Everything happen than I was driving back home and my bike suddenly stopped (engine turned off). I tried to make it run again, but in kickstart or if I pushed in gear nothing happen. But I must say that if I tried to start with kickstart without gas and choke my bike for 3 seconds was running low rpm (1000 I think). ALSO, there is compression, kickstart move not easily, and also we tried to put finger on hole where spark plug sits , we can't hold finger.

I tried to clean carburettor, change new spark plug iridium, put it in cylinder some gasoline (no results). But bike have spark, blue I think, i put it spark near cylinder and few times tried to start engine, there was.

After some calls to dudes who repair motorcycles said that a lot of procents that cdi is broke up. This week I found information that I think almost the same problem happen like me to another guy who have kmx 125. He said that was something wrong with generator windings.

And also, kawasaki kmx 125 original cdi was LIMITER or not? Also how much I need to change piston and rings (in kilometers). And why we need to change piston, if I change only rings than compression will be again good, yes? So whats happen to piston? And about cylinder, after piston and rings rebuild don't need to do some kinda methods to prepare him or I don't know how to say in english .


I really counting on you guys. Need your wisdom what to do .



With best regards,
HardDriver.

" there is compression, kickstart move not easily, and also we tried to put finger on hole where spark plug sits Very Happy, we can't hold finger."

Right, you have some compression

"But bike have spark, blue I think, "

and a spark too by the sound of it

"After some calls to dudes who repair motorcycles said that a lot of procents that cdi is broke up"

If the CDI has failed, its unlikely you'd get any spark

"This week I found information that I think almost the same problem happen like me to another guy who have kmx 125. He said that was something wrong with generator windings"

Again, if the source coils or pulser failed it's unlikely you'd get a spark.

Put the plug back in and try to start with choke
If it doesn't start, remove the plug and see if it's dry or wet

Generally speaking:
If it's dry you have a fuel problem
If it's wet you have an ignition problem

But what about that part then I put gasoline in cylinder a little bit, then I put again spark plug and tryed to start (couldn't start).

[WD Forte]

Ahh
Just realised a KMX125 is a stinky stroke

Stinky - yes. But from 125 I personally choose 2 stroke because they are a lot faster.

[WD Forte]

Kick the bike over a few times with the plug out to clear the cylinder
then
clean the plug and try to start it normally
then
inspect the plug

I will try that, but I still don't get it why bike won't start when I drop some gasoline in cylinder? Whats wrong there?

[HardDriver]

Any ideas?

THANK YOU GUYS for your comments. Found that problem was an crankshaft gland (from magnet side). Because bike is starting but if I little bit throttle it's starting to choke.

I'm just wanting to know how much need to turn out the mixture bolt after full screw in?

Also. What should I know (specific) about engine unravelling?

Thanks.

Then crankshaft collar?

[dangerousdave]

[HardDriver]

Okey. I don't know how to say in english these things, but I will try my best. So, those rubber which crankshaft have, if one of them is failed then motorcycle rpm will be high or it will burn oil or like me. I can't throttle my bike, because of that rubber (it's in theory what happened to engine). If that rubber fail, it sucks air from magnet side.

So I think I explained. But please tell me answers to my previous questions.

[Monkeywrenche...]

Crank seal?

[HardDriver]

Yeah. That one.
