SOURCE: oil out of tail pipe

Hi,
This is not uncommon.
Things to check first would be your fuel mixture. You might be running a bit rich. You should be using a mix of 3.5 percent synthetic oil.
Being a 2 stroke, the tail pipe cartridge needs replacing from time to time, as it does collect oil with time. If the bike is a bit noisey change the packing.
Always remember that there is oil in fuel used on 2 strokes.
Lastly check the type of oil you are using. Mineral oil does tend to be a bit messy as the mixture requires around 5 percent oil.
Most off road stores now keep good LOW SMOKE oils such as Motrex.
Stick to good synthetic oils !
Cheers
Jon

SOURCE: hi i have h plate dtr 125,engine oil is gray cld

the problem arises in this situation because the water system is mixing with the oil system? if i am right in thinking that this is an liquid cooled version with the infamous powervalve system then you might find it usuially has something to do with that. if you keep running th engine then you will find out that it will do lots of damage to your piston which relies on oil to move and cool.

SOURCE: got water and steam coming out of over flow pipe

Clean out your cooling system, flush it and make sure the radiator is not clogged. You could be overheating due to a clogged up radiator. If you put your hand on the radiator, it should be the same temperature all around. If clogged up it will be colder in the middle and very hot where the water comes in from the engine. CAUTION not to burn yourself, use of IR thermometer recommended.
If that's not it, then check your head gaskets.

2001 yz `125 bogs on hard throttle and blows a lot of smoke


Hi, Anonymous and the usual suspects are:
1. Oil tank/pan overfilled.
2. Restricted oil return line to oil tank/pan.
3. Restricted breather operation.
4. Restricted oil filter.
5. Piston rings badly worn or broken.
6. Valve guides worn and or seals worn, crushed, missing, or have come of guide and are literally pumping oil through the valve guide.
7. O-ring damaged or missing from oil pump at crankcase junction (also results in poor engine performance). For more information about your issue and valuable "FREE" downloads that you will need please click on the links below. Good luck and have a nice day.

OIL leaking from my breather hose on top of the crankcase on my ttr 125


Hi, Anonymous oil level readings are taken when the engine has reached normal operating temperature and the usual suspects are:
1. Overfilled oil tank dipstick reading should at or below full.
2. If the sight glass is full you are running to much oil.
3. Excessive blowby caused by worn out piston rings.
4. Piston rings never properly seated.
5. Faulty breather valve or system.
6. Pinched or clogged breather line/hose.
7. Clogged or failed oil filter.
8. Contaminated oil dirt-rust-water etc.
9. Excessive oil foaming.
10. Wrong oil type not designed for your bike.

Oil coming out of air filter


It is quite normal to have a small amount of oil in the airbox, however exsess oil in the airbox will find its way into the engine and burn hence smoke, remove the engine breather pipe from the engine to airbox and clean then replace, exsess crankcase pressure is caused by pressure leaking past the piston or rings, during detanation, dismantling of the top end of the engine is required for inspection, poss new piston and rebore.

Engine oil just disapears but no external leakage


DT yamaha,s are a 2 stroke, the oil is pumped into the engine and burnt with the fuel, at aproximately 30-1 ie: every 30 litres of fuel will burn 1 litre of oil, this is how the engine gets its lubrication , without it the engine will be destroyed, they also have gearbox oil which only lubes the gears and clutch

Oil checking


Here is the manual which may be of help. Not certain if you have a small window low down in the engine that shows oil level or the oil filler has a dipstick...but the manual will have oil amounts which you can measure and refill the crankcase with after you drain the old oil.
rate me please if this is useful or helps your problem.... thank you.
