I have a TM 125 and the radiator water leaks into the motor oil what do i need to fix this

That is a classic symptom of a leaky head gasket. You will need to change this asap to prevent further damage to your engine. You would be as well do ing a piston and base gasket change while your at it. And remember to get a new set of cylinder head bolts, for when you put it all back together again.

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.

I have a 1999 tm 125 and the clutch needs bleeding and wondered how to do it.

Best bet is to get hold of a medical syringe, sounds strange, but bear with me on this. Crack open the banjo bolt on the engine casing and let the fluid run out. Re tighten the banjo bolt. Disconnect the pipe from the lever end, this pipe should now be empty. Now this is where your syringe comes in. Fill syringe with fluid, and squirt it into the pipe, may take a couple of fills. When it is full, re connect it to the master cylinder (lever end) you'll prob have to take the lever off the bars. DO NOT PULL THE LEVER IN !!!! Open master cylinder, fill with fluid, close and try. You may need to do a little bleed again though. If so, fill syringe with fluid, attach a piece of regular petrol line to the end, connect this to bleed nipple on slave cylinder, and crack open (engine end). Open master cylinder cover (on bars), pull lever while injecting fluid. You should see the air bubbles in the master cylinder coming out. Once clear, lock off bleed nipple THEN release lever, close Master cylinder, job done. Sounds worse than it is, and after you have done it a couple of times, its really easy.

Right i own an 03 tm 125 and i took it out got to the track and it wernt starting at all. then bought a new spark plug , it stilll wernt kicking. so i bumped it and it onlky jus started, then rode off...

Sounds like you had the engine flooded or the spark plug was fouled. When you changed the spark plug, you apparently forgot to tighten it properly. You may have damaged the threads in the head. I doubt you blew up the engine but you need to have the treads in the head repaired if they are damaged. Any good machine shop can install an insert into the head to repair it.

How do i adjust the hydrolic clutch on a 2003 tm 125

Normally there is no adjustment of a hydraulic clutch. The slave cylinder is driven the same distance each time the master cylinder is actuated by the clutch lever. Unless you have low fluid, I expect your clutch is slipping due to wear or weak springs or possibly due to additives that should not be used with a wet-plate clutch running in engine oil. Check your owners manual for oil recommendations to make sure you have suitable oil for your bike.

MY TM 125


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.
