You don't need vforce reeds that bike has ridiculous speed and torque for 125 you'll probably beat him without first gear. haha

09 TM EN 300,after the bike is warm and ridden for around an hour or so,it splutters and misses under quarter throttle intermittantly..Clean carby jetted well..Electrical issue im thinking?Anyone...


Check the gap on the points and check to see if they're pitted or burnt. You might just need to clean them with some emery cloth or something similar. If they're pitted or burnt, they need to be replaced

I have a TM 250 around 2000 model. i swapped it for my gas gas txt 280 with someone local. he had bike running fine then water got into stator and so messed up and burnt out stator. he cut wires off...


Hi, Cal_h and the usual suspects are:
1. Fouled spark plugs.
2. Discharged battery, needs to be 12.5 volts or better and be able to pass a "LOAD" test, your battery may show 12.5 volts but has little or zero amps and must be replaced.
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 module.
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 or CDI or electronic control module.
7. Faulty CKP, CMP, or BAS sensor.
8. Faulty ignition switch.
9. Tilt sensor needs a reset.
10. Security alarm failing to disarm needs reset

What gearbox oil is recommended for my 2000 TM racing mx 125


I would only use ATF Type F (Automatic Transmission Fluid) in the TM gearbox mate. Alot of folk use light gear oil, but in my experience, it just isnt up to standard whilst ragging the nuts off the engine. All our race bikes (including our TM) use ATF, and we have had no problems.

Cheers,

Hi im looking for clutch plates and basket that will suit a 02 tm 125 mx and want to know how much this will cost.


Clutch plates vary in price, but if i remember correctly, the TM uses the same as the KX and CR models. Last set i bought cost us 30 pounds. Baskets again vary, best to do a web search but your looking in the region of 100 - 200 pounds for a good one.

I have no spark..thinking coil? also does anyone know what the compression should be on a tm 300 two stroke engine? I am getting 90lbs reading. thanks


Make sure you do the compression with the throttle wide open. (And a clean air filter) You need at least 100 psi to run good. (Kick it untill the gauge needle stops climbing)

MY TM 125


Hi,

The TM 125 uses 550 ml of gear oil. There is level inspection screw situated behind the rear brake lever. Access is a little tricky, but not too tough.
For racing motocross I recomend ATF, but must be changed after each race day.
For enduro, outriding or Sunday riders, BelRay -Trans Oil 80 W is best. You should change oil roughly every 500 km to prolong gearbox life.

Regards

Jon
