[QUOTE="ossagp, post: 199739, member: 1650"] Standard things. Exhaust smoke. Hard starting. Are the valves close to being in spec? The main bearing on the left side of the engine is easy to check. Remove the cover and lean over the seat and pull up and gown on the flywheel rotor. If you feel any movement at all, The bearing is bad and most likely the rod bearing is too. So it's split the cases time. Honestly I wouldn't buy anything that is nearly 17 years old without budgeting for top end Bottom end and some transmission parts and oil pump. [/QUOTE]
