Help Please!!! TRX300 no Spark

Hi, I went to start my 1993 TRX300 2WD today and it won't - no spark.
It has been going well since I purchased it about two years ago. I fitted a new battery and starter solenoid a few weeks ago and it started then no problem (old battery was a bit sad)
There is no power to the coil, I bridged the kill switch and still no spark....
What I don't understand is that it went fine when i last ran it.

Any ideas?

Could it be the CDI? Can they crap out just sitting?

Your help would be appreciated

Thanks,
Brendon
