Whats the best way to clean out a 2 stroke pipe?

My bikes always run rich up to now and the muffler was very clogged. What the best way to clean out the Pro Circuit header pipe.

And while were at it what the best way to clean up the outside of it?

gas torch and burn it out, but you want to do it outside, it produces a shit load of smoke

How hot do I need to go? Red hot?

I have a torch.

now turns out my last hit into a tree has bent it a little so need to fix that up as well. I got a spare stock pipe with the bike so that going on now while I fix the pro circuit up.

does not need to be red hot, you burn it out from the inside,

its the only way i have seen it done,

Have tried lots of methods, burning, caustic soda, but in the end it's quicker and a lot more successful to just cut the thing in half clean it and weld it back together .

If you have access to an oxygen tank, you can use this method.
I've seen it done with oxy-acetylene.
Start the torch and get a blue flame, start heating up the engine end exhaust flange until the inside carbon starts burning, then turn of the acetylene and leave just the oxygen running. The oxygen allows the carbon inside the pipe to continue burning by itself, if its working as it should, you should see a red ring around the outside of the pipe where the carbon is burning. The ring will work its way down the pipe and eventually burn off all the crap inside the pipe.

And that gets the carbon out?

Seems vinegar is popular.

The neighbour from 3 houses down came to check if the garage was on fire when we did this, the neighbour from one house down wasn't very happy about the washing they had out on the line

LOL, Yeah did this heaps in the 70's when I had strokers.. makes a hell of a mess...smoke for miles :violin: Used to take mine out in the country somewhere so it didn't piss the neighbours off too much or attract the attention of the local firey's. Can't do it with chromed road-bike exhausts though...roots the chrome :eek5:

:blink: Just found people that recommend using carrots with condoms on as plugs when you clean the pipe. just be careful how you dispose of said carrot. :shit:

I threw my old IT175 pipe on the 44 g drum bonfire to burn mine out. Very bad idea, there was 4 stroke oil in it as some idiot thought that would work on a 2 stroke. The huge plume of oil cloud could be seen for miles in the middle of summer when there was a fire ban in our rural area..........

LOL!

:lol: Gettin mine done soon, then sandblasted, then painted. Apparently said pipe cleaner has a very big gas bottle attached to a nozzle the size of a wok burner. Should really try & be there for the de-carboning of my spannie. He goes by the moniker of "Jet engine Geoff".

I like to light up a nice braai, and then chuck the whole exhaust on there to cook nicely for a couple of hours.

Enough room on your braai to get your Boer sausage on too?

I should follow your example & chuck it on the barbie:Punk:

Yep most effective and effortless way. Do it at night or somewhere semi-rural so as not to freak out the neighbours. Can take anywhere up to 30 mins depending on how much there is.
