Thanks mate, and no I haven't tried this, guess I took the blokes word that it hadn't been registered, I'll try that tomorrow.
As for good luck with the rebuild, I think I need it, didn't think it would be so hard to get parts, but I guess that's the challenge.
If you have any decent pictures of a 1983 IT please let me know where I can see them, the frame and engine number start with 5Y0, which is why I think it's an '83 model.
Cheers
