I don't know for sure, I do all my work myself. I REFUSE to let a shop touch my bike or cars. Depending on where you go, jets are usually $5-$9 each, and they are super easy to change out. And honestly, it is something you should learn to do on your own if you own a carburated motorcycle. Correct carb tuning is essential for the proper running of your bike and also to prevent catastrophic engine damage. If I'm not mistaken, fuel conditions tend to go lean as you open up the engine and allow it to breath better. What you will want to do is pull out your current main jet from the bottom of the carb, usually you can do this without removing the carb. Just make sure you have a cup to catch the fuel that will drain out. Once you have that jet removed and can see what size it is (it will be stamped on the side of the jet somewhere) take into the parts store and buy 1-3 jets in the next larger sizes, usually you will only need to increase it 1 or 2 sizes. After that, go out and do some plug chops and see where you're at. Just for reference, it only takes me 2 minutes to change out the main jet on my Amal carb.
