Im currently working on a 85 Gs, 250k Miles and still going strong, Ive replaced the Carburator with a Mikuni Side Draft Carb along with a new Intake Designed for the carb, I have Cleaned the hell out of the insides and Painted the Dash Black, Its in the shop right now having some body work done and a Black Paint Job, After this engine dies im planning on putting in a Turbo Rotary...Just not sure which one yet.
