I am trying to sell my 2001 royal star tour deluxe.My first bike was a 2 stroke 1972 r5c.My first love of motorcycles happened when i rode a new 1972 yanaha 650 with electric start.There is a guy here in town that has an 850 triple I would really like to buy if my other bike sells.I am for some reason addicted to yamahas, and especially multicylinder ones.Is the 850 problematic?Is it near impossible to find parts for them?How much should they cost?Thanks for information.
