I bought a 13 tooth sprocket this summer. I took off all the stuff to get the old one off. Went to put the new one on. Would fit around my swingarm. then we checked to see if it was the wrong on. NOPE.. So i was wondering if i could just take off my swingarm(PAIN IN THE ***, FROM WHAT I HAVE HEARD) or just grind a bit off from the sprocket to make it fit? Whatever happenes just say something that might work.
