Book Excerpt: 1959-1979 Vintage Japanese Street Bikes Repair Manual CHAPTER 1 | INTRODUCTION AND TROUBLESHOOTING

FLAT SPOT If the engine seems to die momentarily when the throttle is opened and then recovers, check for a dirty main jet in the carburetor, water in the fuel or an excessively lean mixture. LACK OF POWER Poor condition of rings, pistons or cylinders will cause lack of power and speed. Check that valves are correctly adjusted. Ignition timing should be checked along with the automatic spark advance. OVERHEATING If the engine seems to run too hot all of the time, be sure you are not idling it for long periods. Air cooled engines are not designed to operate at a standstill for any length of time. Heavy stop and go traffic is hard on a motorcycle engine. Spark plugs of the wrong heat range can burn pistons. An excessively lean gas mixture may cause overheating. Check ignition timing. Don't ride in too high a gear Broken or worn rings and valves may permit compression gases to leak past them, heating heads and cylinders excessively. Check oil level and use the proper grade lubricants. BACKFIRING Check that the timing is not advanced too far. Check the automatic advance mechanism for broken or sticking parts. Check fuel for contamination. ENGINE NOISES Experience is needed to diagnose accurately in this area. Noises are hard to differentiate and harder yet to describe. Deep knocking noises usually mean main bearing failure. A slapping noise generally comes from loose pistons. A light knocking noise during acceleration may be a bad connecting rod bearing. Pinging, which sounds like marbles being shaken in a tin can, is caused by ignition advanced too far or gasoline with too low an octane rating. Pinging should be corrected immediately or damage to pistons will result. Compression leaks at the head-cylinder joint will sound like a rapid on and off squeal. PISTON SEIZURE Piston seizure is caused by incorrect piston clearances when fitted, fitting rings with improper end gap, too thin an oil being used, incorrect spark plug heat range or incorrect ignition timing. Overheating from any cause may result in seizure.
