My rm 250 wont spark. When i bought it it had the cdi and coil so i bought a stator and flywheel from a breakers after i fitted the stator and flywheel i tried it there was power comin from the stator but when i tried to see if there was a spark there was nothing so the wire that goes from the cdi to the coil i tried to see if there was power comin from that as i have been told thats what moves the spark from the cdi to the coil (tell me if this is correct) but there was no power. So i bought a cdi from the same guy who sold me the stator and flywheel which came from a runnin bike and tried for spark.... nohing AGAIN so i checked the wire from cdi to coil and no power again and i really doubt both cdi's were fucked so is there something i could be forgettinng or missing out . PLEASE HELP ME
