Dtr125

[jamie1992]

Hi all I have a dtr 125 I am baffled as to what is wrong I have been over 99% of the bike when the key is off I'm getting a spark when the key is turned on the power valve boots up but I lose my spark how could I possibly have a spark with the ignition unplugged I have also noticed that when I disconnect the battery I can get a spark with the key on or off but obviously this means the cdi is getting no power and the power valve will not operate and also the bike wouldn't cut out with the key being turned off any help is very much appreciated thanks in advance
