Looking to make this a solid race bike. It runs good and doesn't seem to be as worn out as it looks, which is a plus. I know zero about these bikes, trying to get as much info as possible, mainly on suspension mods and setup. Need a shop manual. Right off the bat, I see the torque link, rear brake adjuster look wrong. The link is home made and the adjuster rod seems too short. Also, the chain guide is missing some pieces, anyone know of an aftermarket replacement or a new model that fits? Silencer options? Would like something serviceable.
