HELP PLEASE i need to find spare parts hongdou/chituma ctm 125?

can anyone please please help me ive just bought a chituma 125 on a 2005 plate (i know there is mixed opinions about chinese bikes but its just a way to see if i like motorbikes) i really need to find spare parts for it, ive tried chinese parts online but the only response i got from them was "This is not a make and model that we are familiar with" despite there website saying they do stock chituma parts....i have heard that some other manufacturer parts will be ok but im not sure if this is true or which are ok....i am sorry if this is a bit long winded, but surely someone out there can point me in the right direction? many thanks in advance
