Re: 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.

Needle is out. I have 1 notch only on needle. Is it necessary to have the extra washer ?

I put the washer under the cerclip and above plastic washer/spacer thing. I dont think its a big deal not to use another washer, it dont look like its gonna go anywhere.

I cant see how this itty bitty movement of the washer would make such a big difference, its so small, the washer is about a half of 1/8 in depth so to speak. We shall see.

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

Depends on you bike mine is almost straight piped. See the difference from the outer diameter the aluminum washers were to big. The nylon ones worked perfect. The stock needle only has one e- clip setting you would have to buy a carb jetting kit to have a variable needle. The washers help offset the needle for alot less money. And the size of the size of the washer does make a difference as that is what controls the amount of fuel released to the cylinders at mid throttle. The slightest variation can be the difference in 1 drop or 6 at any given moment. Changing the fuel to air ratio dramatically.
