I love the muffler and head pipe. I called pro circuit and they said "we recommend jetting up one size with the addition of the head pipe and muffler, but it won't hurt anything if you dont." When I tried to remove the 4 little screws on the bowl of the carb I started to strip them out. Someone suggested using an impact screwdriver so I bought one, but havent tried it yet. Any other suggestions for removing the screws without destroying them???
