Some kind of insert in exhaust bolt hole???

[RJ138]

My GS450 was missing an exhaust bolt when I picked up. I have been working on getting the bike running and when I went to put in a replacement bolt it won't go it. I examined it a little further and there is an insert or something in the bolt hole. The insert does not have any threads so I don't really know why it is in there. The picture should give you a good idea what I am trying to explain.



I was thinking about tapping it, but maybe someone has an idea what that insert is for. Any help or info on what I need to do to get this exhaust bolted back up would be very much appreciated. Help me get this bike back on the road!

Thanks,
Ryan

Maybe the PO put it in the hole with the intention of tapping it then forgot to do it. You could try to tap it or just put a helicoil or threadsert (preferred) in there.

Since it's already drilled I just tap it.

Looks like someone drilled the screw but didn't finish the job.

The insert looks like it is smaller than the stock M8 size, more like an M6. I just sized up the tap to the new hole. I guess I will tap it to the M6 or the largest that will work.

I have never seen one of these before. Thanks everyone!

Yeah I agree....looks suspiciously like a drilled out bolt.
