That's nonsense.

Regarding your problem...it sounds like a vacuum leak. Maybe you don't have the CV diaphram seated properly. There's a detent and it only goes in one way. You can use heavy grease to hold it in place while reinstalling the top. Are the vacuum hoses installed correctly ? Is the carb in the rubber intake hose well and tight ?

And finally, did you disturb the float ?

Yes, freer flowing mufflers should get a rejet. That consists of a larger main jet, 1/2 white spacer, and 2 to 2 1/2 turns out on the slow mixture screw (the one behind the plug).

why is that nonsense? it ran good with the full spacer in why the he11 would rejet if u dont need too, i put my 145 main back in with a baffle less muffler and it runs better than the 160 main, i can hit 100mph easy now.

i just hate for u to do all that work and then it doesnt run then u dont know wtf is wrong!

make sure there is no debris holding open the float valve needle,that would flood the engine.

after it dies do u have to crank the engine for a while before it starts?

A white spacer reduced by 1/2 will work perfectly well with the Harley muffler he has. f204, check some diagrams of the carb (on this site IIRC) and make sure you have everything put back together properly. Something is amiss. Make sure the vacuum line from the petc0ck to carb isn't pinched.

So torque, you have staight through exhaust with the stock main jet and you think your bike is jetted properly ? Do a full throttle kill, then read your plug. Running that lean is destructive.
