I began riding the bike with the muffler on but after about 5 miles during the break in it wobbled and fell off. I have since had trouble keeping it attached and when it is attached I have found that the speed is increadibly slow (5-10)mph like it is being severely restricted. I have been riding without the muffler now for about 10-20 mi and have read about the possible damage. Is there any way I can rig my muffler up to give it power? Now I sound like a harley coming down the street!
