Hi all, I have a 1984 Honda CB125RS (single cylinder) and I can't get a spark.
The bike was starting and idling perfectly before this issue, then when I went to kick start her, nothing, not a spark.
I've since replaced with a new coil, stator, spark plug and ignition but nothing.
I assume i'm supposed to have 12v coming from the stator wire going to the points and coil? I'm not getting that. I'm at a loss of where the problem can be, any ideas?
The battery has 12v. When I turn the ignition on, the neutral light lights up and the indicators and horn work.
Thanks for any help guys and gals. Cheers, Michael.

Re: No spark!
Is the woodruf key on the crankshaft in good condition ,if it is poor it can throw the timing out.

Hi, I'll have a check but surely that wouldn't affect the stator not having 12v? Which means the points are getting 12v when needed.

Re: No spark!
The ignition current comes from the generator directly on theses bikes if i remember correctly not from the battery.Like the early points setup on a C50/C70 CG125 flat battery no problem starting.
I would change the points and condenser as the next step,i think this was last version before the 125s went over to CDI.
