If this is already up here I apologize but I have never posted anything up here before. I have a 240 swingarm kit and my bike is stretched 10 inches. I am running the 1/4 inch offset sprocket but my chain is rubbing against the frame and the tire I have a 530 chain and I am running a vortex rear sprocket have anyone ever dealt with this problem before any suggestions on a fix. I would speak to the people that made my arm but he is completly clueless on how to resolve and its been a nightmare since he sent the arm out to me any advice would be appreciated my bike is a 2004 Hayabusa.
