Homemade muffler

[SpyGuy]

is that an altoids tin for your intake manifold? LMAO

Air cleaner, actually ....when you open the box, there's a couple of layers of screen door material, wrapped in about seven or eight layers of pantyhose. The bottom of the can is drilled for ventilation, plus a larger hole to fit over the mouth of the carb.

This is actually an older picture of the bike. Since then, I've been doing some welding, and fabbed up a new chain guard, upper engine mount, and front fender. If you're interested, I'll post up a current shot showing all the fun little things I've done to it.

Ventilate it with a .22LR, shoot through the bottom and it started the hole too.

hah

Post a new pic. I like all the DIY parts.

Okay, you asked for it. Here's a collage of the various things I've done to The Rat:

My friends always get a huge kick out of seeing this bike whenever we go out for practice. Considering that this was originally an $80.00 CraigsList special and had been VERY badly abused by the previous owner, it was an interesting rebuild.

ya, you did a good job. I got my muffler welded up yesterday(ill post a pic later). The tank turned out to be 1/32" on the top, so i ended up making a huge glob of weld to fill the holes i burned in it. The muffler works great though, and looks and sounds awesome.

i pull both the schrader valves out and dunk it in a bath of water. It takes a special long nose tool though so i supose you could just hold them in but it would take much longer to fill. When bubles stop coming out its full

schrader valve removal tool? seems to work the best for me

yea all the ones i have are short so i made one from a basketball air pump needle lol

 

[devino246]

Im making a new pipe for the muffler. Right now its just taped together and I'll weld it later. Any problems you could see?

 

[SpyGuy]

. o O (I think the blue tape will burn off once you fire up the engine .... )

Maybe put a small elbow bend on the tip to point the exhaust straight back? Other than that, looks good.

 

[devino246]

The blue tape is there to hold it for mock-up. My muffler is gonnna clamp on the end, but adding a removable bend on the end would be good for use as a straight pipe.
