Both of those things will improve power, but if you dont re-jet after adding them youll lose power..

If you ride with no muffler near houses you might lose a riding area also..

The jets are in the carb...pilot and main... you need larger ones to keep up with the increased flow of air.

The carb needs to be taken apart to change the jets... Most Chinese carbs use Keihin jets.

Jets are about $6-7 a piece. Not exactly sure about jet sizes but think my PZ30 had a 109 main and a 41 pilot...Im using a 130 main and a 43 pilot now...Thats good for sea level to about 3500 ft...
