Baffle Mod

[Bikeguy Joe]

I started out with the Livefast 55cc econokit muffler with a tack-y welded baffle made of very very thin galvanized sheet. (photo 1)

I deleted the stock baffle and replaced it with a "Chore Boy" type steel mesh scouring pad, inserted into the muffler can length-wise. (photo 2) One will do, I got a pack of three for 1.68.

I used the old cordless and a 10mm socket to run the threaded rod down through the "packing" (photo 3) and then loctited the whole works together.

The only down side to this experiment is that I won't be running the engine for at least a few days.

May experiment later with larger outlet area and more packing(s).

Choreboy, not just for cleaning crack pipes anymore! Oh yea they make good pot scrubbers too! Keep us posted I have the epa muffler and it's really restrictive! I've been thinkin' similar!

I figured if they stuff it in crack pipes and light the crack with those little propane torches, it would surely stand up to some two stroke smoke!

I know 000 steel wool burns like the dickens, and fibreglass insulation fills up with oil way too fast.

Anyone with a running bike can try it...it takes 5 minutes to do.

I won't have this one up and running for a few more days.

Seems like that one's easier to work with than the longer skinnier ones. I don't think I can get the baffle out of mine.

i tried something like this with a can a packed it with steel wool and some baffles, then stuck it over the end of the stock pipe with the engine running and it didn't make it any quieter. just now i took the guts out of the stock pipe and rode it and it works much better (as everyone has said) but for me it made it stop four cycling and the rpms when higher

Steel wool will burn.

Yes, this type of pipe is easy to work with, which is good, I have four of them.

I plan on setting up the carb to run properly with the packing the way it is as a baseline. I am working on some other stuff...uh, I can't tell you or you know what will happen.

What, we'll pester you for not getting it finished? Or we'll tell you to not do it because you'll blow your motor up?
