no muffler, how to cope?? (for now)

[bronevaya]

so I dont have a muffler (despite my bike coming with two)

I ordered one from a member on here, but its apparently lost in transit and now I have the post office looking for it :(


when I ride it now I get a lot of pops and bangs like its running lean. I have the carb screw backed out a bit (not too much though) and I have a flexible pipe running from the mid pip to the back.

is there anyway to make it run decent for now?

midrange I have a lot of stuttering like it wants to die.
