Trying to install Kewlmetal risers. Got to get bars off first. Need instructions...I thought the obvious was to take my wrench to the nuts under the triple tree and they turn but don't seem to be coming off.
I don't know if this will help, but I just put risers on my retro and had a similer problem. I removed the bracket holding the bars. Then placed a towel around the riser. I put a pair of vise grips on the riser covered by the towel and spun it off from the top. Good Luck!
