Ok calling all GSXR oil cooled gurus. I have a two part question. The picture of my 1100 motor below has a damaged threaded bolt hole. Question # 1 is anyone have ideas on hot to repair this. This of course is for the bolt on Sprocket cover. Question # 2 can any one tell me what size chain goes wit this sprocket. I can't find any markings on it. I know pretty lame ?'s, but I like to get expert opinions.
