Loosen the bracket and any other mount bolts including head pipes if necessary. Get everything as loose as possible, then use a punch smaller than the bolt to pull them together and align bolt holes. Start all bolts before tightening. Make sure to draw all down evenly, turn or two then on to next back and forth. When done make sure to use glass cleaner or some other cleaner to get all oil and finger prints off the pipes, mufflers and heat shields before starting or you may end up with permanent discoloration. Re check all bolts after riding a time or two. Good Luck!!
