I was wondering if anyone could help me with my problem. I have resently purchased a GT2A frame and a 48cc 2 stroke. The rear of the frame has the 135mm opening. I have put a 26inch standard 2 inch wide rim on the back. I had it set in the correct position to be in the middle of the frame. My problem is that the rear drive sprocket and the drive sproket do not match up which in turn is not allowing the tensioner to work on the frame. Is there a spacer for the drive sprocket that i can use to alighn it properly. I am at my wits end. I have had nothing but issues since i bought the frame. Please someone give me a hand i would give mad respect if you could guys thanks
