This is the first DT I restored. My son been using it until the other day when he said it started making a noise and died. Now won`t start..checked to find there is no spark after trying 2 different plugs. Have not stripped yet but what can I expect to find?..woodruff key sheared..coil suspect...

You have the bike in front of you -  we have keyboards - go discover!

Happened to me this year, on an LC350,  the rotor came loose, ,[ rumble ] ..  luckily the key was whole.

Rex " I see you do the stator/ soarse coil ,ignition set-up for the DT250/400 , I will be online for one in the new year ,

Blackhat I need that rev counter on that LC...was just outbid in the last minute on ebay for one.

You tried getting a DT rotor off, they don't do loose.

Check the wiring, the cdi/mag source coil wiring runs past the exhaust at the back of the tank, exhaust side and can catch if its moved and earth out the coil wiring on the pipe.

I found this out AFTER pushing it home..
