2003 Yamaha Roadstar Owners Manual
Hi, David before testing any electrical component in the Starting Circuit it is 'IMPERATIVE' that you have a fully charged battery of 12.5 volts or more and be able to pass a proper 'LOAD' test if necessary, you may have a preliminary reading of 12.5 volts or more but little or zero amperage, the battery is faulty and must be replaced. AGM type batteries fall into this scenario more so than lead-acid batteries. Ignition Switch not in the 'ON' position. Engine Run Switch in the 'OFF' position. Engine Run Switch is 'FAULTY' or corroded.
Check the battery terminals for damage or corrosion check the battery cables at 'BOTH' ends for loose, corroded, or broken connectors, 'INSIDE' and outside the cable harness, perform connector wiggle test and check cables with an ohmmeter. Bank angle sensor needs a reset or is faulty.
FOB battery low or dead. Faulty ignition switch. Faulty starter button. Faulty kickstand, clutch, neutral safety switch. Security alarm needs a reset. Starter relay, solenoid, starter motor or circuit wiring faulty.
Starter armature or field coils have failed. Main fuse or circuit breaker may be blown or faulty.
Faulty ignition relay. The electric starter is working but starter clutch has failed. Check for engine trouble codes.

Severely discharged or a damaged battery, should have 12.5 volts or better and be able to pass a 'LOAD' test 'WARNING' you can have 12.5 volts or better but little or zero amps and the battery must be replaced. Check battery terminals for damage or corrosion, check the battery cables at 'BOTH' ends for loose, corroded, or broken connectors, 'INSIDE' and outside the cable harness, perform connector wiggle test and check cables with an ohmmeter if necessary. Faulty main circuit breaker and or connections. Faulty ignition coil and or connections. Faulty spark plug, oil or gas fouled, wrong heat range or service type, wrong gap, loose in the cylinder head, broken electrode or insulator. Faulty spark plug cables, leaking or broken, internal damage check for spark leakage in the dark.
Faulty ignition module, switch, CKP, MAP, CMP, sensor and or any connector in the ignition circuit could have corroded, loose, or broken pins/sockets 8.

There is a tool pouch under the seat.In it there is a tool for removing the spark plugs. I would recommend that you at least remove the gas tank.It'll make it a little easier to remove and replace the plugs. But, before you remove the plugs.Take an air compressor with a blow gun and blow out the spark plug ports, so no dirt or debris gets into the cylinder.
Remove one spark plug wire at a time.Blow the port out.Then remove the plug.Check it and if it's good, re-check the gap and reinstall the plug.Put the wire back on and move to the next plug. Repeat the above. Make sure you don't cross-thread the plugs when you reinstall them.Make sure the wires are firmly on the plugs.And make sure you put the right wire on the right plug, which shouldn't be a problem if you only remove one at a time. And also make sure when you reinstall the gas tank that the fuel lines are firmly seated. Removing and replacing your spark plugs is fairly easy.
Answered on Aug 29, 2014. Backfiring and cutting out liike this is probably a symptom of one or both of the following: too rich a fuel mixture, or too weak a spark. Take your spark plugs and see if they tips look tan or black. If black, your fuel mixture needs to be leaned out. Another possible cause is a dirty and or clooged air filter, which can reduce the air flow into the engine. Take it out, bang the dust and debris out.
If it looks really dirty, replace it - they're cheap. If your spark is too weak, you may also notice a loss of power, especially at higher revs. If none of these seem to be the culprit, have your ignition timing checked. Answered on Apr 20, 2014.

All bike are to be checked in the upright position! Then find out how much the bike takes from your manual if you dont have a manual.do the following.when you just change oil and not filter you will be adding less oil,'almost' all bikes take @ 3 quarts oil minimum, so what i do to be safe!! Is always after draining is put in two quarts no problem, but with the third bottle i only pour in half. Drop oil cap back on and start the bike and let it run for a minute, the turn it back off, then check oil level, if it doesn't register anything on the stick or sight glass then your o.k. To add the rest. Now take a reading, and only fill to almost full, i always under fill my bikes, because over filling will cause damage to internal bearing by the air bubbles from the splashing of the crank in the oil pan.
Same as cars. If you found this helpful can i get a rating? Thanks Answered on Aug 19, 2010.
