Welcome to the forum eglintonw,
What other changes have you made to your bike besides the pod filter ?

 

[eglintonw]

K&N Pod Filter, dual straight pipes, K&N crank case air filter

It was a while ago, but I'm fairly sure I went up 2 sizes. The tell tale sign is 3rd or 4th gear wide open throttle to high rpm. If it stalls mid range go up a jet.

What size would you recommend? What is the standard size?

Standard is #122. And I can't exactly remember which size I ended up with but it was a couple of sizes. Every bike is different so buy a few and experiment

You might consider adding some type of baffle to your exh. to give just a little back-pressure for low-midrange running,it'll help w/ tuning also.
