I have a KTM rc390 ..been riding 900 kms after my last service..I changed my head gasket too...what could be the problem??
 
There are several posts about this, you may want to search if you haven't already.
Anyway:
The oil pressure sensor seems to be kind of sensitive, make sure:
You check the oil level using the instructions in the manual, and make sure it's fully up to temp.
Make sure you have the correct weight oil, and I'd use motorex, I know it shouldn't make a difference, so just a suggestion.
Make sure you use an OEM filter.

Some people have also experienced issues with the water pump seals leaking.
You should be able to check this by draining and examining the coolant.
In cases with the bad water pump seals oil has gotten in the coolant instead of the other way round.

And of course since you changed the head gasket, make sure there's no coolant in the oil.

There may be other items I've forgotten.
