Lighting coil
Rick:
Yup, the manufacturing error resulted in a lighting coil that was so thick that the flywheel could not be reinstalled. I'm still waiting on an answer from Electrex on when the correct part will be manufactured.
On the extra cash for the 200 Watt unit, don't want to approach this Mrs. with that option yet, as I still have not solved the lighting problem on my son's KX125. Don't want to buy a coil at $189 for a bike I will sell at the end of 2004, so he will probably just be running a rechargable battery on the 125. I'm only looking to help get back to the van if we stay out too late, so the light only needs to work for an hour or so, which is why the rechargable battery might work out just fine. I plan to only run one of the 35 watt bulbs on his system, so should not draw much juice. Now all I need is a suitable sealed battery.
With this post, I was hoping to find someone with a used lighting coil laying around. It appears that my only hope is Manny.

Moose and Steahly sell lighting coils for the 500,not sure if there made by Electrex or not.Did you also try Baja Designs?As far as the 125, Steahly has a lighting kit that runs off the coil to run the power jet carb,not real bright but itll get you home.Or get a battery and charger from Wal-Mart that powers the kids rideable plastic toys,12 or 6volt, and rig one up.

Mikesmith,
Thanks for the update. Unfortunately, all of the KX500 coils are made by Electrex, so they are all bad. You are 100% on the money on the battery, but that is the last resort. However, once I get the lighting coil worked out, I might add a small rechargable battery to provide better lighting at idle.
Also, on the 125, since a power jet carb was not used on the 2002 KX125, the kit that runs off the power jet carb for the KX250 will not work. I tested the CDI on the KX125 last week, and found DC voltage, but only 5 volts. Unfortunatly, I don't believe DC voltage can not be stepped up with a transformer like AC voltage can, so out of luck on using the stock ingition system.
My current thought is to just wind my own lighting coil. I have an old KX500 stator coil and have removed the wire. Tonight, I will rewind the coil with 14 guage solid copper wire, all in the same direction. This should give me DC voltage, but not sure if I will have enough voltage or wattage. As long as the voltage is great than 12 volts, the regulator will control the additional volts, so I just need to get to 12 volts or above. I will probably have to rewind the coil plate a couple of times to get the correct wire length/gauge, and might have to use a diode if I can't get DC voltage.
On the 125, the stator has lots of extra lugs, so once I figure out the wire length and gauge for the 500 I can then just insulate a couple of lugs on the 125 stator and wrap on the wire (again making sure I wrap all the same direction). I'll let everyone know how this experiment turns out, and will keep good notes on wire length and gauge in case someone wants to duplicate the process. If there are any electornics folks out there than can provide some guidance, it would be great. I'm just an old gear head that knows a little about a lot of different things, so not affraid to experiment.
This is the kind of stuff I love.

Although I have a lighting coil on my bike (Electrex) I don't have a spare untill I get a newer flywheel and E-line accessories fancy expensive jobbie :(
Untill I get that sorted I still need mine despite the fact that it could'nt power a glow worms arse :roll:
Sorry

As far as I can remember from doing Magnetic particle weld inspection years ago the main thing to get right is the number of turns of wire.
I seem to remember seeing a website with info on winding your own bike coils a while ago so I will see if I can ratch it out and post it on here for you
