Default FOAK: Exhaust question

Dear FOAK,

You have very kindly helped me out before and I'd quite like to pester
you again:

I was just checking the oil and the book said to run the bike for 3-5
minutes, so I did, and i put my hand underneath the bike by the rear
wheel to have prod of something and felt moving air on my hand.

So I had closer look, and it seems there is a small hole where the end
bit of the exhaust (the fat bit) joins the thin bit and gas is coming
out. I looked in the book and there is nothing about it in there, so
should it be there or not?

The hole seems to be smooth and so I think it should be there, but as
I'm very new to this sort of thing, I'm not totally sure.

Here are a couple of photos I took, if it helps

http://www.holway.org/dave/Bike/imgdir2.php

(the pictures are about 700kb in total)

It's an XR125L (2003 model) and has 4100 miles on the clock from new,
and only been serviced by the dealer, but I did put some oil in a while
back.

Thanks in advance,

Dave.

Is there any soot round the hole?

IANAE, but I thought an exhaust was only meant to have holes at each
end.

Looks very rusty for a year old bike

The hole is to let condensation drain out of the can. There's probably
another one in the lowest part of the pipe.

Nope. Steel ones would rust through in no time without a drain hole.

As regards the rust, it's stored outside and I don't have a cover and
ridden all year round, TBH, cleaning the underneath has only just
occured to me. I'll invest in a cover.

Thank you for the information as regards the hole, though.

Looks like a condensation drain.

You know, IANAE, but I reckon it might just be a hole to let out the
condensation, like.

Well you live and learn. I remember one of my old bikes suddenly blew a
big hole at the bottom of the pipe. That wasn't stainless steel.

Daubing old engine oil or the like on with a paintbrush might help. Or not,
but it's the sort of thing I do.
