Exhaust DIY Exhaust Pipe

they arent THAT loud with out the exhaust. i can still hear the cicadas over the roar...i can still hear bats squeaking but, despite a youth spent playing and listening to metal music :) yes, i do have tinnitus, i need a fan to be on when im sleeping...


i found a welder on the side of the road yesterday :) works, too!


all i can think of, if you dont have access to much but big washers and a drill... make a stack of washers, spaced out along some fairly long studs... and then try and find a steel aerosol can and mount that over the top of everything... at least it would be some type of baffle, but then again...they arent THAT loud without the muffler! not compared to say, a lil kx80... which is still louder WITH a muffler...


but, to keep everyone in your street happy...buy a muffler.


if you know a plumber with a sutable tap, you could try threading the port, aka briggs and stratton style, and simply screw steel plumbing pipe on? some of thes ethings have round ports... theyre even quieter with no muffler if you can get all that goop BEHIND you ;)

Or he could put the threaded tube on the briggs sausage/pancake style muffler into the hole of that big washer, then flare the end of the tube with a ball peen hammer so it doesn't come out.

And about that free welder, I might be moving to austrailia now!:giggle:
Or maybe it was a microwave and you took out the transformer lol

Btw I love the sig, basically sums up everything that I was taught in health class lol

lol, thats a good idea if it will clear the frame!

its only a stick welder, but seeing as my wizz bang TIG/stick has blown up...very handy :)


the sig....it had a lot more in it, and after falling over laughing i had to do a lot of editing to get within the character limit! theres 12 points in total ;)

I understand why you did it. It's just more satisfying to fix it with something you have laying around than installing a new part. My wife will never understand that satisfaction.

True that, I always end up having more fun on a bike I made out of old junk than one I invested a lot of time/money into. Cuz your expectations are lower, and it's no biggie if something breaks.

If it's something that won't damage the rest of the engine if it fails (ie. Exhaust), and you don't mind tinkering, why not jerry-rig it?
 
I always find myself up fixing up old motors and cassette players and other things that I find at the dump. Lots of brand new lawnmowers that were thrown out because they wouldn't start, when in the end it was just flooded. If I had the space I would fix them up and sell them. Most of the stuff there still works perfectly. I'm pretty cheap:giggle:

bins at hardware stores are pretty good too :) it really is amazing how many people cant tell the difference between PREMIX and straight oil... the customer AND the guy behind the counter that considers a fuel tank full of oil as a genuine warranty return... tip...not many places go to the effort of sending all these returns back to the supplier!


(get friendly with someone that works there and get notified when ever things do come in ;) first in best dressed i say)


was fixing a lil concrete vibrator for someone earlier... fell on its side. oil out the breather, straight into carb. simple fix. drain the oil out of the bowl. then wash all the oil out of the (paper) air filter... $50 for half hour doing doodly squat :giggle: thankfully, cus working on ANYTHING to do with concrete...is the pits :(
 
Far too much has been posted to reply line by line... As far as being loud without the muffler.. Yes, it's loud, but not so much when you are riding it. I thought it had a good sound to it, actually, but was told by a friend that he could hear me coming up the road more than a minute away. With the fact that I sometimes have to leave the house at 5am to get to work, it would definitely be better to have an exhaust. I haven't seen the stock mufflers for as little as $15.. more like double that. I was hoping not to pay that much for another stock anything when an upgrade is so little more. Never the less, I can afford nothing at the moment. I took me more than 6 months to find a job (never taken that long), and it's a crappy minimum wage part time cashier position for Dollar General. The place I live costs $500 a month and I make less than $650 a month, so no electric, etc... Working for change, but having to make do with what I have until I can make that change happen.

As far as the copper, I had no idea if it would work, but I would rather try something than just sit back and whine about what's wrong, and if it had have worked, I would have been super happy. It didn't, so I move on. I may get another pipe whenever I can afford one, or I did notice that O'Rielly's has flexible exhaust tubing for pretty cheap, so am considering that. Alternatively, I've seen exhaust made from electrical conduit and have some of proper diameter. It isn't exactly easy to bend, but I might be able to get something done out of it. Still, I have to figure out how I'll attach a flange to that for attaching it to the motor.
 
you need a mate that will do a favour ;) you might just get lucky if you go hassle a few workshops...any mechanic should have a welder lying around...they might even want an assistant, etc etc etc... hey, one guy round here doesnt mind me using his surface grinder or bridgeport mill...as long as its quiet at the time. he refuses to take money!


THERE IS NO HARM IN TRYING :)

if buying a welder isnt an option...try looking up the "microwave welder". can get away with a pencil lead as an electrode, etc...

even big car batteries work if you try.


times are tough in the US,im told. sorry bout that :( maybe if they had kept the CEO wages in check, and kept all them factories they used to make things in... strange how one guy cant pay a power bill, yet someone else can just go buy a lambo....and pay with CASH.... and who does more work? the poor one :( rich a-hole can pay a law firm to tweak his tax return so he pays as little as possible... the law firm makes more from him than what he pays in tax! thats just wrong!

isnt detroit considered broke? half the streetlights arent turned on, the other half need new bulbs, etc? yet some of the cars that once came from there sell for what some of those guys earn in five years! at least!


what happened to cincinnati machines?

technically, i havent worked in 6 months... heh heh heh. still havent resorted to handouts at the dole office but! mow a few lawns...rebuild the odd engine. maybe i should start advertising?
 
There are a lot of factors at play when it comes to the current economy. I'll try to keep politics out of the engine pages, lol. But, yeah. I've looked into the microwave method and had two microwaves I had collected with intent to make a welder. I was waiting until I got electricity to rip them apart, but recently sold one of them for some quick cash. Eventually, I may try that. Right now, I'm looking for some car batteries. I've seen where you can restore old batteries using an alum/water mixture, so I really want to try that out. If I can get a couple of batteries, I can charge them with my little generator (two stroke 1200w beast) and give it a try. You mentioned using pencil lead. Would that be a replacement for the "rods"? Does it give a decent weld? I've never heard of this.

carbon arc welding. becomes a bit more like TIG, where you need the filler rod. the carbon itself tends to produce the shielding gas.

probably better to just use standard electrodes, really ;) good old 6013, 2mm if you can find them that thin anymore!

and be careful with microwave trannies! they spit out unregulated 1000v + normally you rewind the secondary with heavy guage wire, and a lot less turns!


using a car battery (or 3, really, need at least 30 volts...) you run the current through one side of a transformer, use it as a big inductor. keeps the arc smooth.
