Ryan,

You can either;  1) add more turns to the primary,  2) add more 
capacitance, or 3) shorten the secondary.  Having said that, I would
not shorten the secondary, because tall secondaries usually give
better performance in general (although there are many factors).
Another reason not to shorten the secondary is that you may have
to shorten it too much to make it tune properly.

Cheers,
