I have a 2001 yz426f that I think it needs a new CDI ignition box. My friend has the same bike except for his is a 2000. Will his CDI box work on mine? I know they have separate part numbers but I have heard they are compatible. Please help. Thank you.

i can give you a little help, the rectifier is part of the charging system. it converts110volt from your alt. to 12 volts. it sounds like you have covered all the ign. possibiltys look for something simple ,like bad connections broken wires ect.

follow the plug wire back to the coil and see if there are any breaks, if not might switch coil with the other one and see if the other plug now misfires, if so replace the coil, most cdi problems are not intermittent, typically they either work, or they dont.

you run the positive lead from the cdi to the positive lead on the coil.... then somewhere between the negative lead on the coil and the frame/engine ground you splice in the kill switch.........what that does is breaks the ground when you push the kill switch which then kills the spark to the motor
