Do i need bigger main jets?

... , pod filters aren't great with CV carbs , not sure why I've never had any luck . I think the air rushing past is too turbulent to maintain steady jetting , an airbox is more stable at delivering air at a constant rate

It is possible for pods to work with CV-type carbs, it just takes a little more work. The rest of your statement is spot-on.

The BS-series (CV-type) carbs have vent ports around the inlet of the carbs. Some pods can block those ports, which wreaks havoc with jetting. Some pods might leave a little bit of room, but that can induce turbulence, with equally disastrous results. The intake boots in a stock airbox actually act like velocity stacks, which clean up the airflow. Their inlets just happen to be surrounded by a plenum which is fed by a common air filter.

...Usually make one change at a time so you can track results better.

I?ve never tried using those cheap pods, so I can?t speak from experience, but they seem to be universally despised. You should probably avoid messing with them.
Stock exhaust?

I installed APEs (which I had to cover about 90% - no exaggeration - to get it rideable). I then rode it to my tuner who ordered a Dynojet Stage 3 kit which he used to jet it on his Dynojet Dynamometer. He said the Stage 3 kit was the proper way to do it and the dynamometer made it quicker and easier.

Of course your pods and exhaust are still unknown to us.
