Whether you'll need to rejet, is a matter of what other mods you have, and your location...
Temps, humidity, and elevation...

If that is your only mod,... the worst that will happen is your pipe may blue a little...
If yer' worried about that,.. try popping in #150 main jet.. that alone will get you close...
If you are higher 3k elevation... you probably don't need to do anything...

This is all assuming that your muffler is stock baffled and not drilled out...

I live near sea level. I put on the dyna with no carb mods and noticed an immediate degradation in mid-range performance and MPGs. Loud back fire when decelerating on the freeway.

I'm jetted up one stage now (147.5 main) with the white spacer at 1/2 thickness, performance and MPGs have noticeably improved. I still have soft backfire when changing gears.

One mistake that I made was not double checking my jet sizes before I ordered jets, now I need to re-order the #55 pilot.

I would suggest budgeting time to pull the carb, replace the "phillips" screws on the top and bottom of the carb, and do the spacer mod right away (prolly less than $5). Note the size of your stock pilot and main, and order 2-3 stages up for the main and 1 stage up for the pilot, as well as a replacement bowl gasket.

The closer I get to having this machine dialed in, the more I feel like I own the machine. But then I've only had the thing for 8 years. Grin

If you can see from one end to the other....with nothing blocking your view...then the center plug has been drilled or punched out....or it is not a real DYNA muffler.

The DYNA muffler allows the exhaust to flow into the pipe at the front of the muffler, and then in the middle of the length is a plug that forces the exhaust to exit through a bunch of holes in the pipe. The exhaust flows through these holes and enters the outer chamber where the sound bounces around.....then the exhaust flows through a series of holes on the backside of that plug and into the center pipe....then the exhaust flows out the back.

If the center plug is gone, you can get a freeze plug at the auto stores and drive it into the center of the muffler.....I believe is is a 1-1/4" freeze plug that fits properly. Drive it in from the inlet side - just in case there is a burr or something left over from the original plug....that will help hold the new one in place.

A real Dyna can be gotten for about 30.00 or less. Sometimes and education costs money. I have a PhD in "Stupid" that's cost me a few grand over the years.

One trick I learned recently one newb to another. I'm pretty confident I have mixtures dialed in as much as Im comfortable playing with pilot screws etc. bike didnt backfire while riding but did at shutdown like yours. Solution from an old hat..is a way my dad used to shut down his bikes in the 70s. Pull choke out. Bike shuts down, no backfire.

My PhD in stupid other stuff, not so much but now that the ex is paid off I can afford some of the tuition now.
