Had a lot of problems getting this heap to run, well that is now ok, except that instead of not wanting to go, it now doesn't want to stop! It was all ok when it was in bits, I've replaced the usual coil, genny, pulse pickup in fact anything to do with the ignition. So now it's running again (my daughters chuffed) so I put it back together, gave it a wipe down and started it up. Lovely stuff, it's running fine. Switched it off with the kill switch (as I have been doing for the last 2 days) and nothing happened. Tried the ignition switch, still nothing happened. Anyone any idea what might be the issue? As I've said it's had a heap of new stuff and it's working well, I even changed the cdi box but it still don't want to stop. Help appreciated.
Thanks for your reply, I had the kill switch apart and all seems ok. I'll have a look at the ignition switch in the morning. I've been thinking to convert it to DC ignition which I think will be more controllable.
Could be the "kill" from the CDI come loose? I'm pretty sure it grounds out the CDI to kill it, if that kill ground is loose, it won't shut off
I don't think that is the problem because it wont start with the kill switch switched off, so I'm guessing it must be doing what it should. I get what you're saying regarding a break in the line to the kill switch and will certainly check it out. Thank you for your reply George
Hmmm... Check the ignition switch is plugged in. Also worth spraying some wd40 or whatever in both ign switch and kill switch
Thanks, I'll do that. I've got some Duck Oil (I prefer it to WD40 cos it never dries out) I'll give it a good dosing. Got to be something weird that it don't want to stop.
Well, we're up and running so back to normal again... After the fun and games I decided that if I didn't sort it today, I've got a gallon of petrol and a match Got me tester out and started checking for continuity. Couldn't find any open circuits, so I went round again but this time I decided to unplug the cdi end and the kill switch plug end and check them unplugged. I found the B+W kill wire from the cdi box was open circuit, further inspection I found the wire had a kink in it, opened it up and found a parted wire, with black ends, I cut it back to nice clean wire and soldered it together and sealed it with a shrink tube. All done, plugged it all back in and hey presto, works like a dream. The reason I didn't find the break first time round was because when I was testing I had to hold the tester probes on the cdi cable with one hand and reach to the handle bars to check the kill switch end with the other, I reckon I closed the break so it looked ok. It showed up when it was dangling free. I can save the petrol for the tank now Thank you to everyone who gave their help, it was very much appreciated. George
Good question, I can only surmise that being very close to the plastic bodywork it maybe got trapped at a 90 degree angle and with vibrations (as per normal with small high revving engines) had eventually broken the wire, the black colour says it was open to the elements, so it had happened over an extended time period. Something to be aware of when checking your own circuits in future. Cheers George
