well here it goes i have a 1991 kx 250 which had no spark when i received the bike, so i went and replace the cdi,coil and stator nothing else to replace. I made sure the timing is correct and im still not getting any spark after installing all parts, also i measured the resistance across the stator and that is within in range, but when i measured the ranges on the cdi this did not match, the cdi came of a working bike some im not sure what exactly is going on. also the kill switch was disconneted. Is there anyone else out there who can tell me when can cause this problem i am at my wits end and im not an expert on this just a hobbiest. PLEASE HELP NEED HELP SOS.
