Colpitt Oscillator - need help

So I am designing a Colpitt's Oscillator and cannot seem to get the frequency up to anywhere near 100 MHz. I was hoping someone would be able to give me some insight/advice.

@Zarbanzo, you expect 100MHz so your simspeed must be around 5ns/s now its 80us/s which is good for 1/80us = 12.5kHz. Anyway your filter configuration is 14nH 2nF/2 which results into 42MHz resonance. Get 100nH and 25.3pF × 2 = ~50pF check this http://everycircuit.com/circuit/4748435168428032
