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.
