hi all, got my side stand switch fixed and took her out for a spin and had yet another problem. When im riding it and take off it kinda sputters unless i crack it all the way open and then it runs out great. It seems that the problem is is just like at half throttle taking off,it just sputters. A ny suggestins? The bike had sat for about six months before i got it. also it is a gsf600s
