You running a carb? If so, which one, and does it have a filter right up by the carb intake? Also, what kind of battery & did it leak any/all of the electrolytes from the cells? Also, check all of the ground wires & any connectors along the lines leading out from the battery & the brain box. Check all your plug wires & coil & distributer. A tough weekend on your 17 year old rig can cause all manner of failures that are completely unrelated to a specific incident. Oh, as an afterthought, check your rotor cap for cracks, that is famous for going out on the old 258s.
