i left my sppedfight 2 for about 3 weeks and battery went flat i charged it and after useing it for acouple of days it went flat again so i have changed and cleaned battery terminal replaced battery and replaced reculator and still goes flat after a couple of days only when you use the bike dont go flat if you do use it
My bike does the same i got a brand new battery charged it fully and after a day its deal well I'm guessing it is as the light flicker and they are dim and the rear light flickers so guessing it's dead. Is it the generator ? If so where do you find this

to check that you need the bike running and check the current in ac that the generator is creating with a multimeter and there also should be continuity between the charging wire from the generator i think they are either 2 yellow or 2 white on that machine.

my bike as a after market cdi non immobaliser battery only goes flat when engines running doesnt go flat when left standing

If not battery you have a drain on it. I would suspect your cdi/ immobaliser as these run when bike is off and will kill your battery. Before getting a new one get it checked out cause they are not cheap.

If you battery is more than a few years old it is more than likely the battery thats at fault. I would get a new one.
Good news it is being charged when you run bike. Shop around though battery prices can vary a lot. Check the back of motorcycle news.
