I have owned one for 3 years and sadly I was rearended and lost it,well when I bought it it came with 2 manuals and a publication and in this book that some one put together about this bike I found everything I needed to know. This bike was the 1982 bike of the year, it out performed every one in its class and it was the first bike to have an onboard computer system (your system check) this bike was equiped with anti dive sespention, and would run a 3/4 mile in 11.4 sec the only thing I would call a problem with this bike is it has a tendancy to woble at high speeds( like most older bikes). If you are interested in the book or any repair manuals or just have a ? email me at wontforgethisone@aol.com oh by the way if you have one keep it will be worth alot some day, this bike was a milestone ,have fun and safe riddin
