Remouken Posted August 8, 2015 Share Posted August 8, 2015 hi guys recently brought Yamaha mt 03 2 months ago, going sweet until I change the engine oil and oil filter, I follow YouTube vids right and I over filled it, then immediately drained some back out, was good til I checked next day was below so topped it up and was spot on, then the engine was cutting out occasionally when I give it a little bit of Rev only in neutral and first, then the engine management light kept coming on and going off, it got worse gradually after 2 weeks after changed oil, i thought might be carb dirty, so put some red ex carb adhesive cleaner in, during my ride today I had to stop because engine management light was on too frequent so I checked the engine oil and I could see it at the brim, no way I over filled it that much, so my guess is maybe the engine oil resivaour pump maybe? I'm not that experienced with motorbikes yet, what's your opinion peeps? Thanks. Link to comment Share on other sites More sharing options...
slice Posted August 9, 2015 Share Posted August 9, 2015 (edited) As far as I know the oil CAN'T go up and down like that, Is it possible to check the oil flow through the engine? it does sound like you have a blockage in one of your oil ways, try an engine flush oil (motorcycle) treatment, will mean you have to dump your present oil once you have done it but might save you from a blown engine, that's the best I can figure from the info you have supplied but are you SURE that it has the right amount of oil in it, if it was me I would drain out the present oil and refill it to be absolutely sure I had the right amount in it before I did anything, try putting just 1/2 litre in at a time, fill it slowly and allow the oil time to settle each time before pouring more in, use a measuring jug to be sure each time and use the info in your manual as a guide. PS is it on the side stand or main stand when you fill it? Edited August 9, 2015 by slice 2 Link to comment Share on other sites More sharing options...
Tommy xs Posted August 9, 2015 Share Posted August 9, 2015 Oil may drop after you first fill but after you topped it up to the correct level it shouldn't go up futher have you dropped any of the oil a second time if so did if look normal in consistency, it could be contaminated with petrol! Also .are you sure yor bike has carbs? 1 Link to comment Share on other sites More sharing options...
Remouken Posted August 9, 2015 Author Share Posted August 9, 2015 Thanks slice and Tommy xs, I will flush the engine and change oil maybe to Less dense oil, I don't know if I can check the oil flow :s, the bike was sat on by a friend and held up right, and idk Tommy it did look like more watery but could be because I was on long ish ride could petrol get in there? And I guess it has carbs I don't know much lol. Thanks tho Link to comment Share on other sites More sharing options...
Moderator Cynic Posted August 9, 2015 Moderator Share Posted August 9, 2015 Have you not got a manual.The XTZ tenere that shares the engine uses a semi dry sump with 2 drains. If you only drained the engine, then dumped 3 or 4 litres in there it will end up way overfull.My TDR has multiple drains for the gearbox, the second of which you would likely never notice without reading the manual first. 2 Link to comment Share on other sites More sharing options...

Remouken Posted August 14, 2015 Author Share Posted August 14, 2015 Yeah cynic I got a manual I checked it and yes I did drain out of both drain holes, haven't been able to get to my bike yet, (work) :/. I'm just going to buy some different oil, and flush out the existing oil, see if that un clogs anything, and of course I did drewpy, I found this; Is the engine a dry sump unit - i.e. the oil goes into a tank rather than the engine itself?If so - the missing oil may well be in the engine sump. There could be two reasons for it being in the sump. The first is that the check valve that stops the oil flowing back into the sump isn't working, allowing the oil to drain into it when the engine's not running.The second is that the scavenge pump (that pumps the oil back to the tank) isn't working. In this latter case it would also starve the engine of oil, leading to a damaged crank....maybe the check valve could be jammed shut, stopping any flow to the engine.

slice Posted August 14, 2015 Share Posted August 14, 2015 So basically your fucked if it's open and fucked if it's closed Yes? Sounds like a strip down and check the valve for problems. Link to comment Share on other sites More sharing options...
