If you have a 250 cdi, or a picture of one, they might, or might not, be similar. There's a pic here:

And if you didn't pick up on it, Jack sells brand new ones specifically for the 450.

Keepin' all the left over parts. Gonna use 'em to build another bike!

So does and they sell them cheaper and shipping is less. But my question was not where to buy a new one, simply would like to know if there are any differences between the 2. Since 450s are hard to come by maybe someone knows someone they can borrow a 250 cdi from to verify there 450 cdi is bad. But it seems you only want to stir the pot with me for some reason.

Never tried but....looking at the wiring diagrams I have...
ignition-power-coil in, kill-when-grounded by run/stop or key-off, pickup-coil-in, permanant-ground, one-out-to-both-sparkplug-coils, seem to correspond in the wiring diagram (can't guarantee what the pin-outs are)

Gen2 has a nanny wire that gets connected to ground by either the kickstand-up switch or the Trans-in-N switch, you could connect that to permamant ground since the Gen1 harness doesn't have that.

I can't say that the internal specs such as spark-advance or ignition-power-coil power demand are identical, but both being similar class honda engines and other's have had success with hot-wiring a Gen2 250 CDI on a Gen1 250 harness, so if you are willing to spend the money to try one out....good luck

the pin-out appears the same on 450 as 2nd gen 250 comparing both wiring diagrams
only 5 pins are connected on 450 as it doesn't have stand safety interlock
