Hey all; Story short I need to replace or rebuild my motor. My bike mechanic mate says the left cylinder rod is dead (bearings?). He said it would be cheaper to replace the motor then to pull apart the existing one and repair etc because the damage inside is unknown. I was advised that a wreckers in melbourne somewhere (forgot the location they told me) swap dead engines for working ones. My question is; what stays on the motor when you swap it?? Carby's? coolant lines (rigid or hose)? sensors / wires? starter motor? sprocket? I also found a motor on a classifieds site, that said the motor was fine with a blown gearbox. Is it worth getting such a motor and replacing the gear internals or too much time and effort? Any advice would be great, thanks in advance.
