Hi ave got a ktm 125sx 02 its just had a bottom and top end rebuild bike starts and runs great but there is still a rattle from the engine could anybody help thanks
Lots of engines make characteristic noises and air-cooled 2-strokes have lots of characteristic noises even when new and even when there is nothing wrong.
If you have just spent a parcel of money on it your first port of call should be to the person or dealer who carried out the work. Having a top and bottom overhaul means a world of different things to different people. If you don't know what has been done and what needed to be done you will be somewhat in the dark and at a disadvantage with perhaps unrealistic expectations.
Perhaps the engine hasn't had as much of an overhaul as you thought. A full bottom end overhaul is a good deal of cash and lots of work that would make it as good as a new engine again. Maybe the dealer decided for reasons of economy to refit some of the old parts instead of replacing everything. I suggest you read your invoice and then go and ask some leading questions.
