What jets do you have in there right now and what's your intake situation?

Welcome to the site.
If you have the stock airbox you should be able to keep the stock jetting.
Putting your location and year/model of your bike in your signature is always a good idea.

Don't know as I'm not good with tech stuff was wanting to know which ones to get for a mechanic to do

Impossible to say what to buy without knowing what you already have or how it's running. You don't need a jet kit for that exhaust... but if it also has pods, it may have a jet kit in it already. ... or go back to stock everything.
That said, I can't help but to think you might just let the mechanic tell you what to buy if you can't identify an air filter.

First off, if you plan on owning a 37 year old bike you might want to get better at working on it. These ole gals usually need a lot of attention at first. Years of maintenance that has been neglected. If you choose to live in the dark and not work on your own bike then I would suggest that you find a better mechanic that knows how to work on these. Any quality mechanic who's schooled in the older bikes should be able to figure out what's needed quite easily. Trying to get an internet forum to figure out what jetting you need without a lot of detailed information on what and how the bike is running is fruitless.
