there right bast*rds some times it seems that the most simple thing cause them to not start bit like my daughter , sounds to me that you need some one who knows what there doing ,needs to have a look at your bike like if it bump starts ,,not in your flat ,, its got to be the starting electrics so battery starter switch wiring to starter or even the starter I had a right problem with mine put a new loom on in the end , then it started only to play up turned out to be a duff plug altho it was new, now its not charging if I can be any help with some electric al wiring parts let me know
