Bad ignition

I have problem with ignition coil. To ignition coil imputs double (-) .. is it correct? By scheme is one cable (-) correct, but second?

I am really confused of that because in plug cabels would have been (+) I think..

thank you for every tip..

Yep two cables and 1 coil. Its a wasted spark as it fires both plugs at the same time.

yes.. two cables.. it fits:

but where is 1 coil? .. maybe photo will be better because it must something miss on my kr1s

(like in oilpump case

)

The coil is under the reticifier at the front under the tank. The two wires connect to it on the LHS.

What is LHS?

is this correct? (Cables, (+) (-) ) etc..

could be problem in CDI unit? ..

left hand side(lhs) ...................n thats your coil......wires in from loom on the right of the picture and the leads to the spark plugs on the left....you can put either lead to the spark plugs.......

ok.. but I cant understand this:

plug takes (-) from ground (frame) and where it takes (+) if there is only (-) cables connected into coil??

plug needs both - (+) and (-), yes?

( I am so sorry - I am not dumb .. I only didnt understand correctly

)

Yes you are correct the coil fires both plugs at the same time twice every revolution so one of the sparks is wasted as that piston is at the bottom. thats why it only needs the one coil and only two wires.

ok..

today I look into CDI and find this..

how to recognize if cdi is ok or not?

today I tryed to look for resistance of ignition coil and nubers fits with manual.. so it looks that coil is ok? I think..

Have you checked the stator? They are a common part that fails.

no.. could you tell me where is it and how to make inspection? I didnt found it in manual

thanks alot

the stator is located behind the rotor (flywheel) which in turn lives in front of the final drive sprocket (front sprocket). the flywheel will be under a round plastic cover (black). hope this helps, the stator are prone to failiure as elf has pointed out, if so a zeeltronic unit would be a good idea as there based toward your country i think? very good value aswell as been highly adjustable with diffrent maps etc. go to a breakers for a coil if you find it is faulty as any wasted spark coil should workn just check there the same in all the important values(if they vary from bike to bike?)

I made inspection of stator and I found this:

some wires looks like cut but I dont know where it should be conected.. can you help me? foto of good stator would be best

thanks a lot

the wire between the coil windings are normal, they do look as tho they go nowhere at a glance hence why they look as though they've been cut but they all look like that. i would check the wire from the stator up to the connector block for breakages or check the windings very carefully and if neccesery you can have them rewound. i suggest borrowing another stator known to work and see how the bikes ignition system behaves now.

yes, check the wires going to the connectors.

last time mine was apart I noticed that they had rubbed against the flywheel, looks like yours may have done the same. there is a clip to keep them in place but it seems they can still move around a bit.
