wats up guys?? ive been having some problems with my blaster over the last few weeks. today my friend and i were riding it pretty hard and then i just stalled it.. i kicked it for about 10 times to find out the gas was gone..... got some more gas and it took me like 30 kicks to get it started...... it sounds like the top end is loose and it has a whistling sound to it too.... what do you think it is?? any help would be greatly appreciated!!
