Hi Boys and Girls !!
I have restored a XL500s, see it here. http://www.bluemountain-guitars.de/xl500s.htm
Anybody needing me to source parts, send a Private message or email.
I live in Germany where there is a large group who lovingly rebuild these bikes, so parts (Some new, some Used) are available, even that hard-to-find 23" front tire.
It's a great Bike and a piece of Enduro history. There is also a way to practically eliminate the usual tappet cover oil leak too.
Nice to see so many entheusiasts out there!
