I did it! I cut my muffler off and added a new one.

Needle shim is easy i did it with the carb on the bike. Just remove throttle cables loosen the clamps and turn the top to the right side of the bike. Remove the 4 screws with a ph2 screw driver and carefully remove the top lid the spring is right behind it. Then gently remove the needle jets slide diaphragm. Hold the hard plastic bottom of the slide diaphragm and use a set of needle nose pliers to cautiously remove the white jet retainer in the throat of the jet diaphragm... another spring.... pull the spring and jet out. Lay the needle jet on a table so that the open side to the e-clip is facing the table place your finger on the back of the e-clip to keep it from flying and press the needle jet down to remove the e-clip from the jet. Next slide the thick washer from the bottom side of the needle jet to above the e-clip location. Then re install the e- clip. I used nylon washers as well on the top of that washer. I used 1 m5 nylon washer. And re assemble the carb.
