swarf in exhast - tale of woe

[fish]

Hi,

A sad tale of a broken exhaust heat guard screw, so drill out and re tap --
then tap breaks off in thread - ooo drat I said.

The only way I got it out was to break it up bit by bit.
In the end it got pushed right through into down pipe.

I now have a number of bit of broken metal in my exhaust. They must be somewhere around the junction at the bottom now.

My first thought is what the heck that will be ok, there is no way that can be a problem, but it's starting to bug me now.

I'm getting the view that a Transalp is a serious high maintenance bike.
What with the corrosion, the ease at which threads strip. cables which snap plus my gift at turning a problem into a crisis, it's in the workshop a lot.

I really dont want to take the exhaust off, do I?
