When I bought my 1996 Buell Motorcycle......I also sprung for the FACTORY service manual. Even back then, it was almost $200. A LOT of money in 96! But it tells you about EVERY nut and bolt, torque spec......fluids and gasket sealing. ANYTHING you may need to know.
Yes expensive.......but if you do a lot of work on the same thing......it is PRICELESS!!
