Thanks for the pictures & story, was just hoping to see some more 'new & big jobs' posts here. Excellent.
About reposting pics, thanks for taking the time to upload to the forum, many times things have got lost here because of changes done to external hosting, and pictures in posts here ending up with some 'photobucket not found' placeholder instead of the interesting & important pictures.
That regulator will need some special attention :O) The aircleaner box is a sparse item afaik, looks in good condition, next the hunt for the rubber connector! All in all seems like many good parts there.
