i have a set front street bars and with the acme springer they are bolted to, they are not tall enough for the grips to not hit the tank with the forks turned lock to lock. so i have some options, 1 make a new set now that i have a tig or make these taller. Here's how I'm thinking of making them taller. take a 1/2 inch bolt that is 2 inches long and cut the head off. thread it into the existing bars then make up a spacer out of the same size bar stock and weld a 1/2 inch bung into each end. this will allow me to thread one end snug up to the existing bars and butt weld it. then the other end with 1/2 inch bungs to mount to the top clamp.
