1984 dr250 no spark issues

Recommended Posts

My 1984 dr250s had a very weak spark swapped out with a different coil and still weak spark and took like 40 kicks to start cold but once warm started 1st kick, now it has cut out and has no spark.

Ive fitted a new spark plug. Tested the trigger coil cold at 65ohms and hot at 93ohms 

Can any universal coil be made to fit like a 12v one?

And ideas what it might be? 

Can i test the ignitor box? If so what tests?

Hi,

 

The CDI (ignitor) on the '80's DR250S is a pile of cr@p and is well known to break down. I can supply you with a scan of the multimeter tests from the OEM service manual if you still need them. I use an aftermarket CDI on my '82 DR250S which works ok.
