I got a Husaberg 470. Its a great bike defenantly a recomendation for someone wanting to get a new bike. I needed to take the valve cover off and two allen head screws are stripped. How can I take these screws out. I know that drilling it and using a eay out will work but I kinda want to use the screws again because the bike abeing a husaberg, parts are kinda hard to find. Any help?
