Peugeot 103 u3 exhaust pipe clean up.

My exhaust looks like this:

The inside looks like this:

I'd like the exhaust to NOT be covered in leaky shit so I figured I would throw it in the Weber and repaint it.

Inside looks good right? And when it came off the engine there was no gasket, should there be a crush washer?

Bike was riding fine before so I figured I'd break it.

I'm cleaning the carb also so hopefully that fixes what ever was leaking on pipe.

I started by blasting this thing with oven cleaner.

Tomorrow I'm gonna hose it off and paint it with the oven black.

I might sand it?

Since the inside is fine

Re: Peugeot 103 u3 exhaust pipe clean up.

Why not clean the inside , too ?

That way you start out like brand new . ;)

And , yes , sand as much of the rust off as possible .

Before I sand....

Glad I blasted the inside. So much carbon came out

Re: Peugeot 103 u3 exhaust pipe clean up.

Indeed on the right track- oven cleaner inside and out - give the outside a goodly scrub with a wire brush and a couple of squirts of your fave high temperature paint

Re: Peugeot 103 u3 exhaust pipe clean up.

Got job for sure. A clean inside is way more important that a clean outside. I love using grill paint on exhaust pipes it hold up real well.

Re: Peugeot 103 u3 exhaust pipe clean up.

Did I over do it?

Also discovered a crack at the top of the pipe.... is it trashed?

The crack goes half way around

Looks good , but for the crack .

I'd weld it ( inside ) and run it .

I'd also run a support off the bolt that holds the rear cap on , if there isn't one there already .

What you mean?

There is a bracket that braces it, where would a support off the end attach? Got a pic?

If that bracket affords enough support , run it .

Drill-stop the ends of the crack and weld it from the inside and you will be golden.

Man I wish I could do this myself.

Someday

Re: Peugeot 103 u3 exhaust pipe clean up.

Get yourself a cheaper wire welder and practice - before you know it you will be better at welding and have to use a grinder less.

I have 20+ years of soldering experience so I bet welding is like that, bit on crack. And I might burn the house down

Cracked fixed!

I highly recommend A-1 welding in north hollywood.... he did this for 25 bucks.

Now....

Got the VHT 1200

Do I spray every inch of the pipe? The thread and nut ? Cap and bolts?

Sweet. Ceramic header paint holds up great.

I always fuck up spraying shit.
