no spark on 50 sx junior

[2001CR 250]

I have a 2001 KTM 50 and it stalled at the track today and won't restart I checked the plug and no spark I took the coil of and found a little corrosion on the pick ups so I cleaned them up and still no spark I'm thinking the coil is faulty and suggestion my sons first race is tommorow:

I'd bet it's the coil or maybe the pickup. Same thing happened to my sons Jr. about 3 miles from the truck :(

Coil

The top engine mount probably broke and you lost enough ground to short your coil. It appears to have happened to a lot of KTM 50s.

Yup,
I had to find another ground and replace the coil after a year or so.
