I just got an email back from PiaggioUSA about getting a replacement copy of the owners manual for my LT150.
they sent me a link to a pdf for a Liberty 125, which is much nicer than using the ET4 manual I found online.http://pubblicazioni.piaggio.com/cda/fi ... 197533.pdf
I thought I'd share it here since I've seen some other posts about getting an LT150 manual.
Also, if you chop off the end of that link you can find a directory of all the manuals for piaggio scooters. http://pubblicazioni.piaggio.com/cda/files/pdflight/
It's organized using some numeric catalog system that I cant' make any sense of, but it looks like it's something worth knowing about.
