Hey Wiley,
Congrats on getting it running!!
The pickup coil and generator coils from the 99-01 CR125s work great with the 00 and 01 CDI, but they have to be mounted on a CR250 stator plate . The 125 flywheels have a different keyway placement.
I would try to stay with the 00 and 01 CR250 flywheel. I know that the 98 flywheel will not fire with the 00 and 01.
By any chance did you try to mount the pickup coil in the original position on the balancer cover? ;0) lol

I have ran a 98 flywheel on a 00-01 stator/cdi

Hey There rsss396.
I tried it and had no luck. ;O(
maybe I have a bad 98 wheel? just tossed it in the pile and moved on to the 00 and 01. It is getting harder to get the 00 or 01 wheel. it would be nice to have other
options. I would like to try others, but don't want to buy a bunch of stuff I cant use.

Ok, I will tell you all what the problem was. Pickups are directional. Whoever was monkeying around with the pickup to begin with, soldered it backwards. As soon as I talked to Ricky Stator he told me to just flip the wires, and low and be hold it worked. What is even more funny now is the wires off the pickup have no color coordination to them at all. It actually looks like the wires are crossed. Wherever that pickup came from the direction is reversed from a standard 01 cr. So now I have a complete 2001 cr ignition on the bike and an extra 2000 cdi, flywheel and the stock Honda stator coil itself. Slowride250r, it's funny that you mention the 125 coils and pickups cause I was gonna try that next if flipping the pickup wires didn't work. So now I learned that the Honda wiring schematic is wrong, a reversed pickup will cause the motor to fire 180 off, the green/white wire from the pickup goes back to ground, just because someone took the time to make the harness look like it just came out of the factory doesn't mean they knew what they were doing, and I hate when people on ebay try to sell you something they know doesn't work.

Goodnight to all,
Mike

CDI's fire on the negative voltage signal coming from the pickup coil, when the flywheels timing tab first passes the pickup coil it creates a positive voltage signal then at the the trailing edge of the tab it creates a negative voltage signal that triggers the CDI.

I did not think that the CDI would fire without seeing the positive signal first but in your case it must be. You would not be 180 degrees off on timing but you would be advance the amount of degrees equal to the length of the timing tab.

I will have to see who in our group has a 98-99 flywheel that we tested but we ran it on my bench tester and everything seemed normal.

rsss
That would be great!!!
I would like to have other options. I feel that the 99 wheel may work, but haven't tried one yet. 98 was an odd year. Honda changed the ignitions on both the 125 and 250,but only used it for one year. they did the same in 99, but the 99 worked better and had good timing curves. the 99 - 00 used all of the same components with the difference being the CDI.
I have simply changed the pickup and generator coil from a 99 CR125 stator over to a 98 CR250 stator plate and wired the plug to match the 00-01 CDI. It leaves you with an extra plug housing to set on the shelf

), but works like a charm!!! I raced that one on my bike all last season and had nothing but success.
I look forward to hearing the results of your testing.
Thanks
Robert
