If it died over a bump, the problem is almost certainly electrical. Check that all the fuses are firmly in place in the fusebox (while you're in there, clean off any corrosion you notice). Have a careful look at the cable that grounds the battery to the frame-- take the bolt off, clean off corrosion (steel wool or fine sandpaper). Try shorting out the contacts from the ignition lock -- maybe one of those wries snapped or came adrift. If it starts or the lights come on, there's your problem. Does this model have a killswitch that could have been bunmped to the "off" position?

1982 Yamaha XT 550 no spark??

Hi, Anonymous and the usual suspects are:
1. Fouled spark plugs.
2. Severely discharged or a damaged battery, should have 12.5 volts or better and be able to pass a load test if necessary.
3. 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.
4. Loose connection at ignition coil or plug between ignition sensor and CDI box.
5. Spark plug cables in bad condition, shorting / leaking, spark plug cable connections loose, check for spark leakage in the dark.
6. Faulty ignition coil, pick up coil, trigger coil or CDI box testing needs to be checked with an ohmmeter at 70 degrees Fahrenheit
7. Faulty safety switches clutch, kickstand, neutral, off/on etc.
8. Faulty ignition switch.

1984 Yamaha XJ 650 wont stay running

hi,this might help,the carbs off the 550 will have smaller idle (pilot) jets,this will not allow enough fuel through at idle,the main jets sound like they are reasonably close,i would pull apart the ones off the 650 and check the jet sizes and then compare them with the ones off the 550,you will probably find that the ones out of the 550 are way to small,change the jets over(if they are compatible..should be)and your problem will most likely go away...hope this helps...cheers

Yamaha xt 125r wont start up

hello, check and see if plug is firing a blue color, if not you may need a stator-pickup coil, i have a 2000 warrior, it is firing, orange and white color, stator neede to be replaced, pickup coil was going out, also check ign coil, these have a problem with getting weak after a while. most likely it is your stator pickup coil, no blue fire from plug, no running the motor. my stator pickup coil was going out. no blue fire from plug, i was told by a yamaha mechanic, no blue fire from plug it will not run, has to be blue, not orange or white looking fire.make sure carb is clean and all jets inside are clean, and air passage ways

Yamaha xt 125 battery problem

RC = ReCharge, either the battery is bad, or drain, but both can be caused by a continuous short circuit on the bike's coil and the body / battery.
