KT 250 ignition cdi was easy to find and I was able to use a MX/DT pickup and rotor on the motor ( that bit was a bit hard to find) if you have a electo sparky or tech friend the hookup is not too hard, I can give you a drawing if you end up with these parts
It is on a YZC 250 motor , gives it good low end response and gets the timing out before pinging in mid range
