04 cr125 no spark?

usually this would be a CDI problem right...should i buy a cdi box off ebay for 70 and try that or could it be something else?

also what year cdi boxes are compatible? i assume an 03 would plug right in?

Have you checked all the wires? Did you disconnect your kill switch and check for spark. You could have a grounded out wire somewhere. I would make sure you check everything before you start buying things that you might not have to get.

true well the guy i am getting the bike from says it runs but it doesnt fire right i think.

It could be the coil, cdi, or magneto.
