Double check for air leaks at the header and muff joints.
wave a lit candle around to detect a leak.

shift popping usually caused by air leaks.
but if you have a really open exhaust, might not be cureable

how bad is it? a pop or a KERPOW?

What were you getting in terms of performance before you swapped out the exhaust? If you killed off your performance there would be no need to ditch the stock pipe...other than dropping 20 lbs and making it look better... Wink

Dropping 20 lbs of ugly is the best reason...
My ex, once suggested I cut my head off for the same reason... -Serow... Huh

Serow- your head can not possibly weigh 20 lb. Wink

Sorry, I could never resist a straight line.

And they only happen when I shift (up or down). It is not an open muffler the Dyna muffler still has the inside intact. I've already checked for leaks on the header and at the joint, there are none. The funny thing is that it does not pop when the choke is out (???)

These bikes backfire...i have a pretty open pipe and you might be able to adjust it slightly by turning the airmix screw 1/8 to 1/4 turn either way...I usually adjust mine depending on the weather but have played with it less and less as I get better at feathering the throttle so it doesn't pop...
There are times when I force it to backfire just for fun...cuz...it's fun... Grin

The white spacer controls the midrange. If it runs smooth under light load in any gear, don't mess w/ the white spacer. If it runs rough, and smoother w/ the choke on 1 click, then a thinner spacer will fix it.

A thinner white spacer WILL NOT stop backfire
stock bikes should have run fairly well before any mods. If it didn't, the problem should be found before any mods are made.

Just my 2 sense worth

Thanks Routy,

The bike was running fine before just a little slow in building up speed. Now, after the mods, its faster and goes even further (MPH) than with the stock settings.
I guess I have to keep on playing with the pilot screw to get that "desired" setting and hopefully the pops will get reduced (it is not a backfire)

Your riding style can be adjusted to minimize the pops. Roll off the throttle slowly when shifting, and make the shift quickly and get into the next gear and back on the throttle without being lazy about it. You don't have to act like you are drag racing - just don't doddle with the clutch in and the throttle fully closed and allow the engine to go back down to idle speed. Same when you are just riding around - don't close the throttle in a hurry if you don't need to - just roll it off slowly and only close it enough to match the new speed.....don't close the throttle more than necessary and then crack it open again. After you experiment with it a bit.....you will learn what does and doesn't work.

I finally got the bike running great (an occasionally pop here and there).
Yes, it is popping but I can live with it, I think I have to play with the pilot screw just like Lancer suggested in his posting related to tuning the carb.
I did replace the white spacer with the three (3) washers and the popping that occurred every time I shifted disappeared. I left the Main at 150 and the Pilot at 52.5 (stock) also got a K&N filter (6595) to replace the stock filter (in the air box). The bike is running great, has lots of power, lots of response, and very, very smooth.
Since the only mod left for me to do was to replace the white spacer I choose to do it from the top without removing the carb (just for the heck of it). Personally, I prefer to take the carb but since I am still learning about the bike I thought I will give it a try. The only thing I would recommend (optional) is to replace the screws on top of the carb that hold the cover for the slide and its components. I got some hex steel screws and that work perfect (next time I need to take them out). See picture below.
So I’m up and running, I am a happy camper, or should I say “a Happy Biker” Cool

Thanks for all your help and suggestions; they “all” are welcome.
Stay safe,
Qwapy

Qwapy,
Glad you have it sorted out. I too ended up keeping the 52.5 pilot. went to a 150 main and 3 washers. I also have the Dyna and K&N drop in. It is cool here but have had it out twice with great throttle response and it is a pleasure to ride a motorcycle that sounds like a motorcycle.

I had Michelin Commander II tires installed Saturday and I was able to get a set of 11.5" Progressive shocks and fork brace by Super Brace on it yesterday. Hope to see a 45 degree day here soon (no Florida na-na-nas please) to see what she feels like on the road.

Nice going and good hunting
