Sorry about the delay, I just plain forgot!
Here is the pipe that I mentioned, only I'm not sure what it was removed from. It was sold to me as a XR100 pipe but it isn't for an XR100, the seller said "Well it's off a Honda 100!" so I assume it was a XL100.I thought you may be able to identify it, but if it isn't correct I'll just hang it back up until I can identify it I suppose.
Tony.
