SERIOUS PROBLEM!
Sounds dangerous mikey, I think youre on the right lines about the wheel bearings, you need to put the bike up on a bottle crate or something, remove the wheel and examine the bearings. you should not feel this looseness as you twist the bars. Also look out for loose fork yoke bolts and worn swing arm bushes, last but not least check for rear wheel alignment, the usual way is to use a long straight edge from the back wheel along the bike to the front wheel, there should be an equal gap at the front of the front tyre and at the back of the front tyre

DT125MX MOTOR OIL
Its a two stroke engine and so it needs two kind of oil. The first is two stroke oil, this is put in the plastic tank on the side of the bike and is pumped directly to a spigot on the side of the carburettor (you may see this pipe coming from the front right of the engine into carb). There is a red coloured oil level warning lamp for this, it should be on permanent in neutral (this is a lamp test facility) and if its on when in gear the level is low and should be topped up immediately. Note if this tank is empty you will have to bleed the pump when you top it up. Because of this set up the is no requirement to pre mix oil/petrol, BUT if you dont know the history of this bike you need to verify that the oil pump is still fitted and functioning (its under a cover at front of engine), and that the cable from the throttle is still functioning on the pulley of this pump. The cable and pulley allow the pump stroke to increase as the throttle is opened wider and vise versa. The other oil is the gearbox oil, you will see a drain plug under the engine. the filling point and dip stick is behind the kick start lever. Use SAE 10W/30 motor oil in here. when settin level from dip stick, hold bike vertical and dont screw dipstick in when dipping. The air filter is an oiled foam type, you do not have to discard it if it looks ok, just wash it in a little petrol (work safely) squeeze out excess petrol but dont wring and leave it to dry, then applly a little two stroke oil and work it in thoroughly, it must be damp but not dripping. Have fun!...Great bikes these

Oops - air filter screws.
With a name like yours, you should find it easy

Chain Pain
No problem Reborne, hope its what you want, trouble with imports is they can be difficult to source parts for, as youre no doubt finding out. Suggest you ring them before ordering to give exact details of your bile., or numbers of teeth on sprockets for example. Also is the original chain endless (ie no split link), would this be a problem to you or do you know someone who could fit a new one?

Chain Pain
Bad news Reborne, thats what it means, new chain and sprocket set required Its the only remedy for a worn out set, cant just replace the chain either because a new chain on worn sprockets will also wear out quickly Anyone know a good supplier for these?? Wemoto? M&P? MPS? Busters?

DT 125 stalling
Maybe spark plug gap slightty too much, is there a choke button mounted on carb, does it work ok when you use that? Having said that, you can usually push those back in fairly quickly so might be pilot jet blocked. How did you get it going BTW?

DT 125 stalling
There must also be a wire that goes to a switch that makes when put in gear, maybe this is it
-
DT 125 stalling
theres only two wires isnt there?, shorting them should do the trick, cant answer specific questions as dont have that bike or a manual. but symptoms are classic side stand switch problems
-
DT 125 stalling
Yes this is likely to be the problem, you need to locate the wires that plugged in to the side stand switch and make up another wire to short them together, or if its a proper bodge job and the ends have been cut strip off some insulation twist the wires together and put them into a terminal block.
