I just put on a Jardine. I used a sleeve left over from a JC Whitney slip on I tried first. You need a sleve because the Jardine fits too loosely over the stock exhaust. This sounds like the graphite ring you bought. I used a stainless steel clamp to secure the muffler to the exhaust pipe. I did not use any sealant and I don't think it's leaking. You do NOT have to change the main jet. I drilled out the brass plug covering the pilot jet screw on the upper right side of the carb and turned it out about 3 turns from the factory setting. This makes the motor idle faster. Then, you will reduce the idle speed by adjusting the idle screw on the left side near the choke. Finally, I removed the seat and tank to get into the carb by removing 4 screws on top of the carb housing. Take the top off, then pull off the rubber diaphram attached to the slide tube. Inside you will see the top of the needle held in place by a plate attached with 2 small screws. Romove the screws to get at the needle. You will now see the infamous WHITE SPACER. It looks like the kind of cheap beads 9 year olds make bracelets with. Take it off the needle and reassemble the whole thing in reverse order. Basically what you've done is enriched the fuel to air mix in the low end of the power band. Your bike will now pull even stronger in the first 3 gears and backfiring will be GONE.
Read as many of the posts on this as you can find. There are much better explanations than what I gave. I used a tight fitting phillips bit in a wratchet and the screws came loose with moderate downward pressure. Others have had much more difficulty with this step. I am pretty much a novice. The entire job took about 3 hours because I quadruple checked everything, cleaned areas I don't otherwise ever see and took the opportunity to try and understand as much about everything as I could. The job can be done in much less time. By the way, I liked the JC Whitney pipe also. It is sytled just like the Jardine, only a bit smaller. It is somewhat louder and to my ear, deeper sounding. I'm actually still undecided which to use permanently. If you are buying new, the JC Whitney is about 1/3 the cost. Both run great and sound great on the Savage. Happy wrenching!
