I'm guessing that since it's a REALLY small engine with no battery, that it's a 6v...
I looked, but haven't found anything on line about it.

He has not had the chance to look at it yet. I'll give him a few more day's.
I was told about NCY¤d¸*³¡«~¾÷¨®¹s¥ó»s³y§åµo
I took a quick look but have not had the time to really see what they have.

Update...I wired up the new XR50 CDI & coil with the new wiring harness to my engine... NOTHING, NO SPARK!!!

I'm sure that the new CDI uses a separate magnetic trigger to fire it, & a stator to power it up.
Our current mag-coils do both off of one wire!
I found a small mag-trigger & stator for a XR50 on Ebay, but it's still too big to fit in the side of our engines... (modify?)

I'll keep looking!

Heres a pic of the XR50 part that I found on ebay... The back plate is 4.5 inches across.
I was thinking that maybe the back plate could be cut down to fit in our engines?

I really think this part will work if I can make it fit into the engine and get the timing set...

Any thoughts??

If you could get it to fit, and use the XRCDI, we are going to 12 volt right? Everybody I have talked to say's the XR is 12 volt.

Got my mag back.......John (MSD dealer) said nothing can be done to improve it. He used smaller wire on the coil winding and bigger wire. He said the smaller wire does improve the juice a very small amount. But not enough to improve performance.

If it will fit VB, yeah, all we have to do is figure the timing. If we can get it to fire on every stroke, and not every other stroke, we should be okay.

I think the way they work is... that they DO fire on every stroke, just every other spark is a dead spark on the exaust stroke!

Your right, I dont know what I was thinking. I'm going to Phoenix Wed. for work. They have a huge motorcycle junk yard, I'm going to go dig around and see what I can find. Hopefully I can find a XR50, it would be alot easier to see what you are working with. I also hope to find some 50cc scooters and see if anything will work.

By the way, I just used the mag my friend looked at. It dont work now.... I dont know what he did and dont see why there is no juice. Maybe changing the coil winding is not a good ideal

I might have to go to these guy's

I think the set up I found on ebay is a better bet... The original equipment on a xr50 is a stator & a big "bell" magnet, that I'm pretty sure wouldn't fit in the engine...
The ebay one is much smaller, & the back plate can be cut. (I hope)
I'm thinking about just buying it and praying I can make it all work.

Anybody doing your timing will need a degree wheel.

I found this place that gives you five diferent sizes of wheels. Just download, print, and cut. Saves 20 buck's. I made mine out of sheetmetal.
