One is a 78 and the other is a 81.
I bought 4 XL250's that should have been junked from a guy in Utah. I
made 2 good bikes from the 4. It was really a tough job because the
bikes had been ridden out in the salt flats around Salt Lake City and
they were really rusted up. Anyway after a lot of time and effort I got
them back to good running condition. The 81 I painted like original but
the 78 I painted like a 72 model paint scheme. I sold them both a couple
months ago and the guys I sold them to love them. I have some extra
parts for the XL's if you know any one who needs some. I have a complete
rolling chases, seat and tank that need a lot of help, etc...
One of my current projects is
helping a friend of my sons fix up a 72 XL250. It is a lot easier
project then the ones I had.
