Question about 1991 Yamaha TZR 250 R

1 Answer

My yamaha tzr125r will only run while the start button held in

I have a tzr125r (4hw) same runnning gear as the tzr250r it just has one cylinder instead of two, all the same running gear etc

my yamaha tzr125r will only run while the start button is held on, once i release it dies, got a feeling its just one wire, but im lost, the starter has power, believe thats all it needs, coil has 2 wires onto it, again believe thats all it needs, but i have 1 random wire im unsure of, coming from the wiring loom itself, i assume its to be arthed but its not doing me any favours earthed or disconnected.

Yamaha Tzr 250 3ma problem - will not run on righthand cyclinder. It appears to run at tickover engine speed, but fails to run at higher engine speeds.


Hi, Barry check your coolant level and power valve linkage, your instrument gauges and lights can alert you to most electrical and engine issues they can not warn you about failed engine gaskets or seals so your engine has to resort to old fashion alert methods of colored "SMOKE SIGNALS" here is a breakdown of their meaning:
1. WHITE SMOKE on start-up can is usually caused by a blown head gasket allowing coolant to enter the combustion chamber and may start dripping out of the exhaust pipes or mufflers.
2. BLUE SMOKE on start-up is usually caused by failed valve seals. Smoke that is constant while riding is usually caused by valve to guide and piston ring clearances that have exceeded service wear limits.
3. BLACK SMOKE on start-up is usually caused by too much fuel in the combustion chamber this can be due to air/fuel mixture adjustment too rich, accelerator pump improperly adjusted, faulty choke/enrichner or not in the off position, faulty carburetor float needle and seat, pilot jet too large, fuel injectors leaking, smoke while riding is usually caused by the main jet being too large.
It should be noted that aggressive or abnormal throttle operation will cause these conditions to manifest themselves exponentially.

Hi, Michael and the usual suspects are:
1. Faulty wiring to any safety switch.
2. Safety switches loose at the mounting point.
3. Faulty kickstand safety switch.
4. Failed kickstand safety switch circuit diode.
5. Stretched side stand spring.
6. Side stand not coming up far enough to disengage switch.
7. Faulty clutch lever safety switch.
8. Faulty neutral safety switch.
9. Clutch not properly adjusted.
10. Clutch plates sticking, forward lurch
